Mapping campaigns

• UN Mappers have opened new humanitarian mapping projects for UN peacekeeping missions:
  • Democratic Republic of Congo
  • Abyei

  The topographic data will support MONUSCO and UNISFA missions to secure peace in the area.

• The first UK Quarterly Project of 2021 is Green Spaces – parks, allotments, playgrounds and commons.
• Pascal Neis pointed out on Twitter that ‘unmapped places‘ is now available worldwide. This was prompted by a tweet by Said Turksever, who has made the Turkish ‘unmapped places’ available for mapping in a MapRoulette task.

Mapping

• OpenInfraMap added a statistics section, showing data about the power network by country. For OSM contributors, this is especially useful to identify mis-tagged power plants.
• The tagging proposal on electricity=*, and the subtags, failed the third vote, with 8 nays on 16 votes cast.
• The proposed tag healthcare=vaccination_centre, for tagging a facility where people are vaccinated, was approved by 20 votes in favour and none against with one abstention.
• Robhubi showed > how a complex multi-function building can be better represented though extending existing building polygons with a greater range of Simple 3D building objects and tags.

Community

• Joy Christine Nduta Kimani, a YouthMapper and a Geomatic engineering student at Jomo Kenyatta University of Agriculture and Technology (JKUAT), shared her experience participating in the URISA Student and Young Professional Digital Competition.
• Yves explained how OpenSnowMap is financed and made a plea for small donations to support the site.
• OpenStreetMap India announced a new Telegram channel for contributors in Rajasthan.
• A newly registered account, which seems to come from China, complained that OpenStreetMap does not follow China’s ‘One China’ policy and ‘correctly’ label Arunachal Pradesh and Taiwan as Chinese territories. The diary post attracted the attention of a member of the Data Working Group, and mappers from China and Taiwan. Previously we reported that Mapbox CN supplies a government-certified map version for China, which does not follow the on-the-ground principle of OpenStreetMap data.

OpenStreetMap Foundation

• Christine Karch is looking for volunteers, with various qualifications, to support the organising team for the SotM, the annual international OpenStreetMap conference.
• Chair of OSMF Allan Mustard announced that the 2021 survey of users and contributors, which we mentioned last week, is now available. The survey will remain open for responses until Sunday 14 February. The announcement raised concerns about whether the survey complies with the GDPR, but Allan Mustard considered them as trolling.
• Christoph Hormann has published > a preview of his traditional report as the FOSSGIS representative on the OSMF Advisory Board at the FOSSGIS General Meeting scheduled for March.

Local chapter news

• The nomination period for the OpenStreetMap US Board Elections will close on Sunday 24 January.

Humanitarian OSM

• In outlining the role of the new open mapping hub for Asia supported by HOT, Rebecca Firth introduces a new term hOSM, meaning humanitarian OpenStreetMap in contradistinction to HOT (Humanitarian OpenStreetMap Team), referring to the US incorporated not-for profit. This difficulty of distinguishing between a broader community of OSM participants with humanitarian interests and the specific activities of HOT has a long history. Just one example is this mailing list exchange back in 2014.
• The HOT upcoming community webinar on Friday 29 January will feature three COVID-19 Rapid Response micrograntees; iLab Liberia, OSM Senegal, and Public Lab Mongolia; and HOT’s COVID-19 activation team. You can read about the micrograntees here and here.
• Kontur has added new layers to their emergency mapping dashboard, Disaster Ninja, to show the most densely populated areas within a priority area for mapping (‘alert polygon’). The Urban Core layer highlights the most densely populated regions inside the hazard area, whilst the Settled Periphery layer complements it, showing the dispersed part of the population in the area.

Maps

• [1] With little fanfare, CyclOSM, a beautiful and practical bicycle-oriented map, was added to the default layers on openstreetmap.org.
• Fun with the map data of Wales: A tutorial with overpass queries and OpenStreetmap can be found here.

Software

• gb consite GmbH has developed a tool with the option of displaying the radius of movement around a clicked map point or a municipality (according to OSM admin_level 6 or 8), county, or Kreisfreie Städte (county-free city) in Germany. The 7-day incidences (from the national public health agency Robert Koch Institut) and the vaccination centres (from OSM) can be shown as overlays.
• The new anti-COVID-19 regulations in Italy allow people living in municipalities with fewer than 5000 inhabitants to move within their region a maximum of 30 km, provincial capitals excluded. Users aborruso, napo and pigreco have created a programme > (the code is on GitHub ) able to define the zone for each municipality concerned.
• IpswichMapper wrote about a new application which they have created to make it easier to collect house numbers when surveying. The app has been published on GitHub.

Programming

• Behind the scenes osm2pgsql is an important piece of software, replicating and manipulating OSM data for map rendering from PostgreSQL databases. Many new features have been added to it recently. The developers have many new ideas and plenty of issues to look at. They are holding a virtual meetup on Tuesday 2 February at 18:00 UTC. After an introduction to their plans the remainder of the meeting is planned as a Q and A session focused on future priorities. Anybody can join; you don’t need to register. We reported earlier about OSMF sponsorship of this project.
• The Chemnitz University of Technology is looking for a research assistant to further develop the mapsforge_flutter rendering library, the components for rendering OSM indoor data, the JOSM plugin indoorhelper, and the indoor mapping of buildings themselves. Click here for the job description. Very good written and spoken German and English skills are required. The application deadline is 13 February.

Releases

• The editorial team alone cannot check the release status of the many software products in the OSM environment. Therefore, we would like to regularly present wambacher’s OSM software watchlist to the community. Walter masters the monitoring of updates with his own programming. The list is updated frequently (usually weekly) and is available in three languages . Beginners, advanced users, all users of OSM, can find OSM software products in the current version with corresponding platform and download options. Walter is also happy for tips, if a piece of OSM software is missing from the list.

Did you know …

• … WeGlide? The new global evaluation platform for glider pilots uses OSM maps to visualise cross-country flights. The project is under development by three German pilots and will be used for competitions in the near future.
• … that Switzerland’s first official topographical map series, the Dufour Map, is celebrating its 175th anniversary? Replicas true to the original are being sold and the map is being made available for digital exploration – visitors can also leave their own traces there.
• … there is a ‘To do list’ JOSM plugin? This adds a to do list dialogue that makes it easy to go through large lists of objects. It helps the user to examine objects one at a time in order to edit or update them.

Other “geo” things

• Lewis Isaacs wrote in The Guardian about GPS art, amusingly described as ‘Human etch-a-sketch‘.
• BBC reported about a three year university research project in Kentucky and Colorado (a US FEDA $900,000 grant to the University of Kentucky) where researchers are training ‘drone cowboys’ to find cattle and assess their health and weight from the air.
• Hydro International reported that the Schmidt Ocean Institute’s research vessel Falkor has collected the first public seafloor data of the New Year, as part of a global effort to map the entire ocean floor by 2030.
• Michael Schultz (Heidelberg University) reported that the Horizon 2020 LandSense project was successfully concluded. A selection of the publications and deliverables produced are linked in the text. The project has enabled the group to pursue quality aspects of voluntarily collected geodata and to ramp up efforts related to OSM Landuse and Landcover.
• Sarah (Heidelberg University) has been investigating street networks and their quality, in order to find out which of the selected regions has the most detailed information in OpenStreetMap, as well as the best data consistency over the past 10 years.
• Matthias Fejes (Chemnitz University of Technology) reported > on approaches to achieving a seamless transition from outdoor to indoor navigation on smartphones for everyone.
• Theo Armour shared his efforts and ‘Mapifesto 2021-01-12’, a public declaration of intentions, opinions, and objectives that give direction to cartographers, mappers, and lovers of ways of representing reality in the many routes to mapping.
• Mapillary is making available Vistas 2.0, a major semantic annotation upgrade to their street-level image dataset (for AI training and validation) of 25,000 images from around the world.

Mapping

• Fernando Trebien has proposed a revision to the highway=trunk classification description in Highway Tag Africa. Pierre Béland and others refer to previous discussions and explain the exceptions applicable in Africa for major inter-Africa networks and propose amending the wiki to refer to the Trans-African Highway network and the Southern African Development Community Regional Trunk Road Network (SADC RTRN).
• Peter Neale (user PeterPan99) has created his first proposal, focused on the key addr:parentstreet. This key is already being used for mapping addresses with two street names, and he suggests it would benefit from being included in the standard tags. The RFC started on 20 January.
• b-unicycling wrote about improving the tagging of historical features in Ireland.
• OpenMap Development Tanzania reported on activities and results from generating community data for improved disaster management and urban planning in Mwanza, Tanzania.
• How are sidewalks typically mapped? With the sidewalk=* tag or as a separate way? Both answers would be wrong; see this analysis (the answer is ‘it depends’, see the analysis as to why).
• MapBeks is mapping three of the 24 most under-mapped towns in the Philippines.
• Mateusz Konieczny has drawn attention to the current ‘no-show paradox‘ in voting on proposals. His proposal to fix this can now be voted on until Tuesday 2 February.
• The vote on the proposal for man_made=guard_stone has begun.
• Voting has started on the tag stone_type=ogham_stone, to map a stone with a Ogham script on it, most commonly found in Ireland as free standing stones, lying on the ground, recycled in buildings such as churches or as artefacts in museums. Voting ends on Monday 8 February.
• Voting is open until Tuesday 9 February for man_made=tailings_pond, a body of liquid or mining slurry used to store the byproducts of mining operations.
• Peter Neale asked on the tagging mailing list how to deal with a ‘messy situation’, and was advised to document it on the wiki, which he has now done. The problem concerns inconsistencies of street names in various sources and on the ground.

Community

• [1] Peter Berger feels > that the Swiss OSM map could do with a layer oriented towards outdoor users. After discussions with Stefan Keller and Rafael Das Gupta he compiled a draft with some illustrated suggestions for path symbology using Maperitive. Various other suggestions have been made in the thread on talk-ch.
• Maning Sambale wrote a short summary of OpenStreetMap activities in the Philippines 2020.
• pietervdvn has started a query on Reddit asking ‘what are the weirdest and most original use cases of OpenStreetMap?’
• Supaplex wrote about Dan Jacobson, who found that the Taiwan Power Company had updated its power pole dataset to use the TWD67 coordinate system. But if you inspect the dataset, you will find that it has some special parameters, and it could not be transformed correctly into WGS84.

OpenStreetMap Foundation

• The OSMF has launched a survey among the OSM community. The survey is available in many languages and ends on Sunday 14 February. Some numbers as of Thursday 28 January, 18:00 UTC: Complete responses 1998, Incomplete responses 767, Total responses 2765, Number of tokens sent 3176.
• Christoph Hormann shared, in a very detailed manner, his would-be answers to the OSMF board survey.

Local chapter news

Humanitarian OSM

• The DRK (German Red Cross) General Secretariat, together with HeiGIT (Heidelberg Institute for Geoinformation Technology at Heidelberg University), have launched > a handbook in the form of a lexicon of organisations and tools involved in mapathons. The handbook is the result of the ’25 Mapathons’ project. The collaboration between these two entities started in 2017 and focused mainly on humanitarian mapping around the international work of the DRC.
• During 2020 OpenStreetMap Senegal received a ‘Rapid Response Microgrant’ to map hospitals and update information on emergency health services. Daniel Abanto Graffman showed how the data evolved over the project’s timeline and the impact of newly available information on emergency services and capacity assessed with the Openrouteservice.
• Nicolas Chavent is running as a candidate for a vacant post on the HOT US Inc. board of directors. He wrote a post with his vision in his OSM diary.

Maps

• William Ray used a range of data, including from OSM, to produce isochrons showing access to amenities in Oxford, based on blended scores of several inputs (shops, green space, healthcare facilities). At present these inputs are not weighted.
• Johnny Harris shares, in a 30 minute video, his experiences making maps.
• Christopher Beddow writes, in his second of three blog posts, about the background and importance of Maps.me.

Programming

• Maptiler provided a more formal announcement of the MapLibre fork of Mapbox GL, which we mentioned in passing at the time of Mapbox GL becoming proprietary software.

Did you know …

• … that MateKa’te shows all of the facilities serving Club-Mate (drink:club-mate=*) that are mapped in OSM?
• … the evaluation by Pascal Neis of an OpenStreetMap contributor’s profile? Admittedly, not quite new, but the ‘old hands’ like to look at the evaluations of other mappers or for a personal sense of achievement on their own profile. Just enter the OSM user name of the mapper you are interested in.

26.01.–01.02.2021

OSM CZ

• Výzva a podklady (mapa na bázi umap) pro kontrolu míst, kde se třídí odpad (kontejnery i centra), která potřebují vylepšit a upřesnit.
• Mirek Suchý nabízí aktualizaci postupu doplňování chybějících poštovních schránek.

OSM SK

• Zajímavá prezentace ohledně nástrojů pro QGIS pro práci s mračny bodů.
• Zajímavý článek o komunitním mapování v oblasti Prešova (a snad se data dostanou i do OSM).

Mapování

• Aktuálně probíhá hlasování o těchto návrzích na mapování:
  • stone_type=ogham_stone pro kameny s nápisy v jazyce Ogham (do pondělí 8. února)
  • wait=* pro definici, ke kterému pruhu patří odpovídající značka stop/give_way/traffic_signals (do středy 10. února);
  • man_made=tailings_pond pro oblasti, kde jsou ukládány pevné nebo kapalné vedlejší produkty při těžbě – nahrazuje reservoir_type=tailings (do středy 10. února)
  • traffic_calming=mini_bumps pro značení malých omezovačů rychlosti instalovaných pro zklidnění dopravy (do čtvrtku 11. února);
  • funeral_hall=* pro označení dostupnosti místa pro pořádání pohřebního obřadu v zařízení jako je krematorium nebo kancelář pohřební služby (do soboty 13. února)
  • healthcare=sample_collection pro tagování místa, kde jsou získávány nebo sbírány vzorky krve, moči apod. pro účely analýzy ze zdravotních důvodů (do úterý 16. února).
• Brian Sperlongano zaslal návrh na tagování odpařovacích nádrží, které jsou používány pro usazování pevných látek buď pro získání nějakého produktu nebo pro jednodušší nakládání s odpady. Navrhovaný tag by chtěl nahradit používání tagu landuse=reservoir pro tyto účely.
• Existuje návrh pro obchody nabízející paletu poštovních služeb buď speciálně pro výdej balíků nebo přidružené služby k jinému obchodu. Není však zcela jasné, jak se to liší od poštovních přepážek v rámci obchodu nebo jiného zařízení.
• Novozélandská designérka Jess Weichler upoutala svým zkoumáním svého rodného města s pomocí StreetComplete v rámci nočního rande se svým partnerem.
• Uživatel M3232 připravil na OSM wiki několik návrhů, jak by měly mapová data a nástroje nakládat s objekty, které leží napříč 180 poledník.
• OrDal píše na izraelském fóru o navrhovaných změnách na relace pokrývající oblasti západního břehu Jordánu. Ty jsou od šestidenní války okupovány Izraelem a částečně jsou spravovány palestinskými úřady a z části židovskými osadníky v rámci Izraele. Cílem navrhovaných změn je lépe reflektovat současnou situaci (on the ground princip). Jeden by očekával, že podobné změny v tak citlivé oblasti vyvolají spoustu odezvy, ale zatím se neozval vůbec nikdo.

Komunita

• Rory McCann (Uživatel ᚛ᚏᚒᚐᚔᚏᚔᚋ᚜ ) nabízí osobní shrnutí svých aktivit v OSM za listopad 2020. Ty zahrnují mapování, tvorbu videí, práci pro Communication Working Group (CWG), záležitosti komunity a práci v radě Nadace OSM.
• Frederik Ramm upozorňuje na to, že mnoho jazykových variant vstupních stránek na wiki pro začátečníky je výrazně zastaralých. To se nyní projevilo například tím, že odkazují na Potlatch 2 jako editor pro webový prohlížeč. Frederik hledá mluvčí některého z těch 45 jazyků, do kterých byl průvodce pro začátečníky přeložen, aby byly provedeny změny ohledně referencí na editor Potlatch 2 na jiný alternativní editor.
• Supaplex a další tchaj-wanští mappeři se rozhodli na měsíčním setkání v Taipei, že budou odstraněny všechny mapové prvky přidané účtem, který zneužil vlastnost systému na rozpoznávání silnic MapwithAI prováděním masivních editací bez kontroly a interpretace výsledků umělé inteligence proti realitě. Detekované objekty tak mohou být vyschlé potoky nebo oblasti pod vedením vysokého napětí. Odstraněny tedy budou všechny cesty nahrané pod tímto účtem, které nebyly následně upravovány.

Importy

• Dongha Hwang oznámil začátek importu z portálu otevřených dat Jižní Koree, konkrétně jde o datové sady s licencí kompatibilní s ODbL. Celý proces je detailně popsán na speciální stránce na wiki.

Nadace OpenStreetMap

• Speciální výbor pro politiku svobodného a otevřeného software Nadace OpenStreetMap publikoval krátkou zprávu inventury softwarových nástrojů používaných pro spolupráci mezi organizací, radou a pracovními skupinami. Zároveň navrhují doporučení, jak zvýšit využívání svobodných a otevřených nástrojů.

Novinky lokálních zastoupení

• Rory McCann (tajemník Nadace OSM) se ptá komunity OSM v Polsku a členů Nadace OSM na žádost sdružení Stowarzyszenie OpenStreetMap Polska stát se oficiálním zastoupením Nadace OSM pro Polsko. Své připomínky a komentáře prosíme zašlete do 14. února 2021.
• 28. ledna 2021 organizovala > německé lokální zastoupení plně virtuální akce nazvanou FOSSGIS-UPDATE. Účastnilo se přes 200 zájemců sledujících živé vysílání, kteří se kromě toho měli možnost potkat ve virtuálních stáncích nebo interagovat v rámci malých skupin na “herní” mapě.
• V čísle 57 podcastu Geomob se Ed Freyfogle rozhodl vyzpovídat Jeze Nicholsona, jednoho z ředitelů OSM UK, lokálního zastoupení Nadace OSM pro Spojení království.

Humanitární OSM

• Missing Maps informují o úspěšné spolupráci s Lékaři bez hranic na kampani proti malárii v Burundi v roce 2020. Missing Maps se zaměřili na aktualizaci dat OSM o budovách v cílové oblasti. Kampaň na hubení komárů dosáhla 97% populace a 98% domů ve třech okresech, které byly střediskem epidemie malárie.

Tato mapa je výsledkem projektu DéCiSiF > laboratoře TREE (CNRS/University of Pau). Data pocházejí z OpenStreetMap a INPN > (Národní seznam přírodních památek).

Software

• Byla vydána počítačová hra NIMBY rails na tvorbu a provozování vlakových tratí. Herní svět je postaven na skutečné geografii postavené na OSM. Menu je k dispozici v 27 jazycích.
• SomeoneElse informuje o svém experimentu se spuštěním Potlatch 3 pod Wine na různých Linuxových instalacích. Většina věcí fungovala úspěšně, ale přesto nabízí několik specifických doporučení jak zabránit pádu, abyste nepřišli o své editace.

Programování

• IpswichMapper oznámil na talk mail listu SwiftAddress (informovali jsme již dříve). V reakci na to Simon Poole upozornil na problém duplikace úsilí při rozvoji OSM software. To následně vyprovokovalo ostrou diskuzi o rozhodnutích vyvíjet nový software nebo raději přizpůsobovat existující kód.
• Branko Kokanovic napsal novou aplikaci pro příkazovou řádku, která na vstupu bere soubory GTFS a řekne, jaké změny jsou potřeba v OSM, aby byly tyto dva zdroje co nejpodobnější. Zdrojový kód aplikace je dostupný na GitLabu.
• V rámci přípravy na nadcházející setkání vývojářů a uživatelů osm2pgsql tento týden připravil Sven Geggus krátký seznam svých požadavků.

Nová vydání

• Bylo nasazeno vydání 5.3 stylu pro hlavní mapu OpenStreetMap Carto. Výraznou změnou je vykreslování mini kruhových objezdů, které se nyní objeví blíže hlavnímu kruháči. Další změny jako částečné indexy na vodních trasách jsou jen pro zlepšení výkonu.
• Projekt OpenMapTiles vydal novou verzi 3.12 s mnoha novými vlastnostmi. Zobecnění budov jako bloků je navrženo pro zlepšení vykreslování hustých městských oblastí pro střední přiblížení mapy. Novinky zahrnují také vodní plochy jako bazény, slané tůňky atd., letištní brány a chráněná území.
• Byla vydána nová verze programu OsmAnd 3.90 pro iOS a 3.9 pro Android.

Věděli jste …

• [1] … o Commute Time Map, která dovoluje vytvářet mapy dosažitelnosti pro různé formy dopravy?
• … že OSM History Viewer umožňuje vizualizovat historii objektů OpenStreetMap a odkázat se na spoustu dalších monitorovacích nástrojů pro OSM??
• … o OSM v reálném čase od Jamese Westmana? Tento web ukazuje sady změn prováděné v OSM s aktualizací stavu každou vteřinu a právě jsme dosáhli sadu číslo 100 milionů. K tomuto výročí pro vás tým WeeklyOSM na příští číslo ještě připravuje malé překvapení.
• … OSGeoLive nabízí statistiky vývoje projektů pro otevřené GIS produkty? Pro každý sledovaný projekt je evidován programovací jazyk, aktivita a vývojovému týmu. K dispozici je statistika za celou dobu od začátku projektu. Z OpenStreetMap editorů je reprezentován iD, JOSM má bohužel problémy na OpenHubu.
• … že Routeshuffle může pomoci s vytvářením náhodných tras pro běhání, chůzi nebo vyjížďky na kole a to vše jen na pár kliknutí? Musíte jen zadat výchozí bod (jménem nebo souřadnicemi), jak dlouhá má trasa být a typ sportu.
• … že se můžete zaseknout na kruháči navěky?

OSM v médiích

• Pokud jste do svého produktu integrovali Mapbox GL JS verze 1.13 nebo starší, zvažte open source fork MapLibre jako alternativu k přechodu na proprietární Mapbox GL JS verze 2.0. Podrobnosti přináší opensource.com.

Ostatní geo záležitosti

• Vyzkoušeli jste si test z King William’s College, o kterém jsme informovali dříve na začátku roku? Nyní se můžete podívat, zda byly vaše odpovědi správné. Ukázalo se, že mohlo pomoci mít inter alia, dobrou znalost hlavních měst států USA, okresů britského Somersetu, Cotswoldsu, Keni a Dublin. Užitečné byli informace i z oblasti geografie Indie nebo anglických novel.
• Malé studium geografie může být nebezpečná věc. Chybějící kontextuální znalost způsobila, že firma Facebook označila jméno známé anglické lokality za urážlivé slovo.
• Lesní úřad Ghany (FCG) nedávno oznámil spuštění národní mapy lesů a využití půdy. Jedná se o zásadní milník ve snaze Ghany vybudovat expertízu pro pozorování země na světové úrovni. Vlastní mapu si můžete prohlédnout zde.

About us

• In a few days (probably 27 February), the 100,000,000th changeset will be published in OpenStreetMap. This counter tool shows the changeset numbers in real time. In the next issue we will update our current projection. The editors of weeklyOSM would like to start a small challenge: the goal is for the mapper of the 100,000,000th CS to contact us (via any known channel). We are keen to conduct a small interview with this user, which will be published, or he or she will be mentioned in weeklyOSM. In addition, there is the possibility of a nice gift from Geofabrik to the lucky mapper: an individually designed large map of the winner’s surroundings, or anywhere else in the world. Good luck!

Mapping

• An old proposal has been revived for tagging couloirs, narrow very steep breaks in mountainous terrain. These are particularly of interest to skiers and mountaineers, who regard them as highly distinctive features, as shown by several comments on the tagging mailing list. (Nabble)
• A proposal has been made for the landuse=shrubs value. This tag would be used on areas in built environments, filled with bushes where barrier=hedge can’t be applied. A tag obviously made for the Knights who say ‘Ni’.
• Reddit user Buster452 wrote about the importance of mapping dead-end roads on the OpenStreetMap subreddit. In his words, ‘It’s passing knowledge on to someone on the ground so they can make a navigation decision whether to take that road or not’.
• Florian Lainez (user overflorian) got over-enthusiastic and made a large mechanical edit without pre-announcing it. The replacement of the tag diplomatic=consulate_general with consulate=consulate_general is broadly accepted but, as ever, the policies should be followed. Consequently the edit was reverted and Florian apologised.
• The tag healthcare=sample_collection was proposed for a ‘site or dedicated healthcare facility where samples of blood/urine/etc. are obtained or collected for the purpose of analysing them for healthcare diagnostics’. The proposal vote is open until Tuesday 16 February.
• Flo Edelmann is asking for feedback on the proposed takeaway:own_dishes=* tag, which specifies whether a takeaway restaurant accepts customers’ own dishes to help reduce packaging waste.
• The proposal to modify the vote counting rules was accepted.

Community

• Seth Deegan (lectrician1) pointed out that they had opened two issue tickets for the main OpenStreetMap website. Both proposed changes relate to the header area. The first proposal is to add a link to the wiki whereas the second is to move the ‘export’ button to the right hand tool pane.
• Mateusz Konieczny proposes running an automated bot edit that will remove tracking parameters from URLs in OSM tags such as website=. The URLs themselves will be preserved, and dubious cases will be flagged for manual review.
• Frederik Ramm asked for self-moderation in the Tagging mailing list, to avoid things like ‘repetition of one’s own arguments’, ‘repetition of someone else’s arguments in different words’, ‘quick-fire responses’, ‘mistaking the list for a voting platform’, or ‘wanting to comment on everything’, among others. (Nabble)
• OpenCage tweeted a small thread of highlights from over five years of OpenStreetMap interviews with communities across the world.
• User SomeoneElse described in detail how to add a resource to the OpenStreetMap Community Index, a project that lists OSM-related resources (in-person and virtual meeting options, mailing lists, chats…) around the world. He details how to clone a GitHub repository.

OpenStreetMap Foundation

• Results of the OSMF 2021 Community Survey will be posted as results become available, starting with basic summary statistics, then additional details as the analysis continues. The raw data will be posted after they have been anonymised so that anyone interested may analyse them. As of 9 February, 4460 tokens had been requested, resulting in 3808 responses of which 2664 were in full. Based on demographic data from the in full responses, 8.08% are female, 89.45% are male, 1.37% are non-binary, and 1.1% are other.
• In his OSM diary, Nicolas Chavent suggests that the OSMF and local chapters formalise the current practice, still unwritten, of banning the provision of paid services as a source of funding, for the sake of their autonomy and internal governance.
• OpenCage and the OSMF announced that the former is now a silver level corporate member. The joint press release describes OpenCage’s geocoding service, which uses OSM data.

Local chapter news

• Rory McCann (OSMF Board) asked the OSM community of Japan, and OSMF members, about OpenStreetMap Foundation Japan’s application to become an official local chapter of the OSMF. Please forward your questions, comments or concerns by Tuesday 16 February 2021.
• OpenStreetMap Belgium’s Mapper of the Month for February is lhennen.

Humanitarian OSM

• Benjamin Herfort, from Heidelberg University, reported about global indicators of mapping related to the HOT Tasking Manager. Analysis in an associated blog post lets us see the progression in the number of contributors since 2012 followed by a decline since 2017. No breakdown of contributors by experience (i.e. days of contribution, objects edited, etc.) is given. The author notes that to associate all these tasks with humanitarian mapping (or all humanitarian mapping with only these tasks) is therefore an oversimplified definition and the results must be taken with a grain of salt.
• Bo Percival (user bo_hot) shared a call for volunteers for an experiment to test the efficiency and efficacy of AI assistance in the remote mapping of buildings. The experiment is organised by HOT, in partnership with NESTA Collective Intelligence grants, and the Netherlands Red Cross. The call for volunteers is open until Saturday 20 February.
• Resilience Mappers from Uganda have won a US$5000 microgrant to enable community engagement and participation in the HOT Summit 2021.

Education

• Rory McCann has shared a video tutorial on how to easily create one click tag presets in JOSM.

Maps

• [1] The Ministry of Health of Peru has created a ‘Vaccination Map’ based on OpenStreetMap. The totals, first and second vaccination, and regional values are broken down for region, province, and district. The locations of vaccination centres are also shown on the map along with a lot of information that can be accessed through the map.

Software

• The GIScience News Blog introduced a new tool based on ohsome. The preliminary results presented by the ohsome Quality AnalysT (OQT) website are about the completeness of mapping in a region (i.e. low level of buildings count vs population and the density of points of interest).

Programming

• OSM tools are often designed for Linux OS and the new WSL2 (Windows Subsystem for Linux) represents a good solution to use them from Windows, as Pierre Béland describes in his OSM diary. He recommends a virtual lightweight Ubuntu 20.04 OS environment to use Linux scripts in a development context on a Windows machine.

Did you know …

• … osm2pgsql, which converts OSM data for import into PostgreSQL databases?

OSM in the media

• The Russian and Ukrainian language media arms of the US-government-funded Radio Free Europe (Крим.Реалії > and Radio Svoboda > ) reported about the Ukrainian Railways objecting to the depiction of the borders of Crimea on OpenStreetMap.
• Local print > media and radio in San Juan (Argentina) covered Guillermo Maldonado’s work mapping the new public transportation system, now nearing completion. Although it is not long before its launch, clear maps of the routes have not yet been published. In order to understand the new network, Guillermo uploaded them to OpenStreetMap and created a uMap with the routes, which has been well received by locals.
• The Deccan Herald profiled Ramya Ragupathy, who works on analytics for the Humanitarian OpenStreetMap Team (HOT), in order to show what’s involved in the multi-disciplinary role of a ‘data scientist’.
• The Inverness Courier reported on volunteer mappers in the UK who are adding buildings on OpenStreetMap in Tanzania, as part of a Crowd2Map initiative to fight female genital mutilation.

Other “geo” things

• Google started to roll out a new version of Google Maps in January 2021, featuring pedestrian oriented details such as pedestrian crossings and pavements. To do so, Google is using an automated system, analysing satellite imagery and Street View.
• Pocketnavigation profiled >
  changes that have been made to the Outdooractive web portal and smartphone app, which now show blocked and closed routes.
• The Swiss Federal Office of Topography, swisstopo, has completed > a seven year process of revising official maps to use digital cartography.

About us

• We already reported on the imminent approach of changeset 100,000,000 on OpenStreetMap, currently expected to occur on 26 February. You can monitor progress with this tool by James Westman and compare against our projection. We will contact the lucky user who uploads this changeset via OSM messaging with a contact address and they have until 1 March to reply. If they would like to participate in a short interview (10 questions), the editors would include this in weeklyOSM #554. In any case, they may receive a prize (no guarantees):The prize: in cooperation with GEOFABRIK a folded print of the OSM in standard Carto style, of a preferably small section, chosen by the winner, on 130 gsm paper in ‘Super A0’ format with 15035 x10559 pixels, approximately 1.20 x 0.91 m in size. The map will be sent free of charge. We ask for your understanding that we will limit the shipping costs to maximum of €25. The map can also be sent rolled up. An example of what the map cut-out would look like. We will clarify details with the winner. We wish dedicated mappers every success.

Mapping campaigns

• Said Turksever tweeted about the completion of a MapRoulette campaign to ensure all the ‘unmapped places‘ in Turkey have their roads mapped (as we reported earlier).

Mapping

• Florian Lohoff pointed to > , on the German Forum, a MapRoulette task which is resulting in airport features mapped as areas (runways, taxiways and aprons) being retagged from aeroway to area:aeroway. This has the effect of the element disappearing from many map renders.
• User Clay_c wrote about the dilemma as to whether underground railway stations are buildings or not. There’s a lot more in the diary post about which tags mappers have used elsewhere, demonstration of indoor tags, and some neat diagrams.
• The ride-share company Lyft blogged about what they see as the benefits of using OpenStreetMap.
• Martijn van Exel gave a video tutorial on a fun and effective method to systematically fix up old TIGER import roads in the USA.
• User mahdi1234 published a short article on how to use Git(Hub) as a way to cache Overpass queries in order to serve data to uMap.
• Requests have been made for comments on the following proposals:
  • cycleway:doorzone=* for indicating that a stretch of cycling infrastructure exposes a cyclist to the risk of dooring (colliding with a motor vehicle’s open door).
  • post_partner=* to tag the availability of postal services in places other than post offices.
  • type=traffic_signals_set a new relation type to group together traffic signal devices corresponding to a single intersection.
  • emergency=lifeguard formalising the use of the existing tag for the permanent, or semi-permanent, location where a lifeguard will be while on duty. Also proposed is a number of values for the key lifeguard=* to further describe where a lifeguard may be found.
• Voting is underway for the following proposals:
  • historic=ogham_stone a second vote on a method of tagging a stone that has Ogham script on it (till Sunday 28 February).
  • basin=evaporation for mapping a basin used to evaporate water (till Tuesday 2 March).
  • boundary=forestry, which aims to standardise the mapping of forest management (forestry) areas (till Tuesday 2 March).
• Voting has ended for the following proposals:
  • man_made=tailings_pond was approved with 32 votes for, 0 votes against, and 0 abstentions.
  • traffic_calming=mini_bumps was approved with 37 votes for, 0 votes against, and 0 abstentions.

Community

• The 2021 board elections for OpenStreetMap US resulted in four members of the board remaining in place. The new member is Diane Fritz, who succeeds Alyssa Wright, a long-time board member who retired from the role this year.
• OSMF board member Rory McCann summarised their OSM-related activities for December.
• Hackernews discussed James Westman’s OSM in real-time site. The weeklyOSM editors particularly liked this comment.
• YouthMappers marked Women in Science day with a blog post on its importance.

Imports

• Sergio Quintero started a thread on the imports mailing list about a Spanish mountain ranges import. This sparked a debate on the verifiability of OSM features. The import is dependent on the decision of the Spanish community, which is still pending. More information about the source of the data can be found on the wiki.

OpenStreetMap Foundation

• Allan Mustard, chairperson of the OSMF Board, sent out a reminder about the OSM 2021 Community Survey, which closed on 14 February, and an initial report of the results. Result processing is ongoing; further results will be available on the survey’s dedicated page.
• Mikel Maron issued an apology, on behalf of the OSMF Board, for overlooking a number of conflicts of interest in the awarding of microgrants in 2020. Both Mikel and Joost Schouppe were closely associated with successful grantees.

Local chapter news

• Since April 2019, Healthsites.io, in partnership with Cartong, Géomatica, and the OpenStreetMap Senegal community, have launched a series of activities to map health facilities in Senegal. This blog post presents the mapping activities in Senegal and results.

Humanitarian OSM

• The Community Working Group of HOT is organising a webinar ‘Colonialism in Open Data and Mapping’, which will be held on Friday 26 February. Topics and discussion points include the balance of community vs. digital information, decolonisation of open data and open mapping, and representation and power in humanitarian mapping.
• Pete Masters, user pedrito1414, reported on HOT’s five-year project in Tanzania.
• Following on from her last diary (as we reported), RebeccaF shared more of her thinking around the principles and purpose underlying the new regional hub structure HOT is setting up, and continues the dialogue and evolution.

Software

• OSM Inspector by Geofabrik, which has had a view for Public Transport routes (version 2 tagging) for some time, now supports new validation rules for stop positions. It now checks whether the stop position is on the route and whether the stop positions of a route are ordered correctly.
• Pieter Fiers (user ubipo) has taken the OSMfocus app and re-released it as OSMfocus Reborn, both on Google Play and F-Droid. OSMfocus Reborn displays details from the OSM database for nearby objects so that they can be compared with observations made on site.

Programming

• The deadline for organisation applications for Google Summer of Code is nearly upon us. Sarah Hoffman (user lonvia) asked, in the dev mailing list, for project ideas to be added to the wiki. OpenStreetMap has participated in the Summer of Code since 2008, although indirectly in 2013 and 2014 via OSGeo.
• Tor Hovland has started a series of blog posts on the process of developing a web app for editing OpenStreetMap data using the Rust language.

Did you know …

• … geocode.xyz, from Ervin Ruci, will allow batch geocoding with a free rate-limited tier?
• … the key traffic_calming=*? On the wiki you can find all the variants illustrated with photos.
• … Peakfinder will generate a digital 360 degree panorama, based on SRTM data, from many places in the world? The names of mountain peaks are mainly sourced from OpenStreetMap. Compare, for instance, this photographic panorama from the summit of Monte Tamaro, Ticino, Switzerland with the generated one.
• … that one cannot always trust the competence of those who install traffic signage? This is particularly true when the installers do not speak one of the languages on the sign.
• … that there is a thread > , on the German forum, with regular updates on Walter Nordmann’s software watchlist? You can also use the thread to suggest other software that should be included on the list.
• … OpenStreetMap Help is a question and answer forum in the style of StackExchange?

OSM in the media

• The internet newspaper Regiotrends reported >
  on new maps of the Strasbourg-Ortenau cross-border region produced by the KartoDistrict >
  project.
• Mark Altaweel wrote about the ‘bystander effect’ on sites using volunteered geographical information (VGI) such as Waze and OpenStreetMap. The article is based on an academic paper by researchers from Michigan. This effect occurs when people are aware that others are already contributing, and therefore are less likely to contribute themselves. The work suggests that the use of targeted interventions might alleviate the problem.

Other “geo” things

• Paul Digney, president of SSSI (the Australian professional surveyors’ organisation) reflected on the events of the last year in the Australian geospatial world. Highlights included the two mapathons that SSSI ran after the 2020 Australian bushfires, the first to map burnt infrastructure in seven different project areas affected by the fires, and a second that concentrated on mapping for bushfire preparedness (we reported earlier).
• Molly Burhans, a cartographer, environmentalist, and Catholic, is working to persuade the Catholic Church to map its holdings to enable better management in the light of climate change.

Breaking news

• Congratulations to Lamine Ndiaye for uploading OSM changeset #100,000,000! He has been mapping since 2013 and was nominated ( and ) for the OSM Awards in 2017. Take a look at how our prediction of when the event would occur turned out. If you missed seeing the big event on James Westman’s OSM In Realtime you can watch TheSwavu’s replay.

Mapping campaigns

• UN Mappers has opened a new mapping project in the Central African Republic (CAR) to edit topographic features. The project welcomes any contribution that helps bring peace to this country, especially in the Bangassou area.

Mapping

• In the course of a mapping action for protected and sanctuary areas > in Germany and Austria, a reference map > for the currently mapped protected and sanctuary areas was created. All protected areas are available as WMS layers as well as GeoJSON and KML exports. More details on XCTrails ReleaseNotes > and technical background > (post #198).
• User quilkin asked, on the forum, about the longest single way on OSM tagged as a highway. Needless to say this provoked some others to investigate. So far it appears that the longest highway mapped as a single way is 462 km of the Birdsville Track in Australia.
• Mateusz Konieczny provided his error reports derived from an evaluation of the quality of Wikidata tags in OSM.
• Requests have been made for comments on the following proposals:
  • place_of_worship=holy_well for a place where Catholics celebrate the well’s patron saint with a mass once a year (‘pattern’), collect ‘holy water’, and sometimes leave votive offerings in the well (coins) or at a nearby wish tree.
  • natural=shrubbery to tag an area of cultivated decorative shrubs or bushes.
  • Coin and note acceptance to specify which coins or notes are accepted by an ATM or vending machine.
• Voting is underway for the following proposals:
  • natural=couloir for a seam, scar, fissure, or vertical crevasse in an otherwise solid mountain mass (till Thursday 4 March).
  • Change vote counting rules to remove the references to ‘rule of thumb’ and ‘other factors may also be considered’ (till Thursday 4 March).
• Voting has ended for the following proposals:
  • wait=* wasn’t successful with 7 votes for, 9 votes against, and no abstentions.

Community

• Paul Norman started plotting the first results of OSMF Community Survey, and made some initial observations about outliers and distribution of data.
• OSMF board member Rory McCann summarised their own OSM activities in January.
• Kai Schröter and colleagues examined whether OpenStreetMap data on buildings are useful for flood vulnerability modelling.
• Rabin Ojha presented an overview of OSM activity in Nepal last year, 2020: from a noticeable increase in map contributions, to long-term projects led by organisations including Kathmandu Living Labs, NAXA, Youth Innovation Lab, YouthMappers and the World Food Programme, among others.

OpenStreetMap Foundation

• PierZen published a list of individual comments related to the diversity and inclusion committee, and the Code of Conduct, from the recent 2021 OSMF Community Survey. An interesting read.
• OSMF Board member Guillaume Rischard (user Stereo) processed the responses regarding Board priorities for 2021 from the OSMF Community Survey.

Local chapter news

• Videos and slides are now available , on YouTube, from the FOSSGIS-Update online conference > held in January.
• OpenStreetMap US thanked Craigslist Charitable Fund for its generous donation and its five-year history of supporting OpenStreetMap US.

Events

• GISRUK (GIS Research UK) Chair Peter Mooney invites you to an online seminar about ‘Semantic geographic knowledge on a world-scale—interlinking OpenStreetMap and knowledge graphs’, to be given by Prof. Dr. Elena Demidova. The lecture will introduce emerging approaches that address tighter integration of OSM and knowledge graphs; it will give particular attention to link discovery and semantic enrichment of OSM datasets. The event is planned for Thursday 25 March at 14:00–15:00 UTC and requires registration.

Humanitarian OSM

• HOT is partnering with OpenMap Development Tanzania (OMDTZ) to pilot the development of investment in mapping communities in Tanzania. The idea is that using a trusted partner at a national level enables better understanding of the nuances of local community needs.
• Rubén Martín (nukeador), HOT Community Strategist and Research Lead, continued his series of blog posts with one on understanding the humanitarian open mapping community. Next month’s will focus on discussions with the newly created Regional Hubs and membership to establish plans of action to support OSM local communities.

Maps

• James Ross (twpol) has created a tile renderer, which renders a road overlay, with lanes, according to various selected tags.
• Romania’s national programming platform for vaccination against COVID-19 makes use of (Romanian) > an OSM-based map to display the locations of vaccination centres.

Open Data

• How the Indian Government has changed its guidelines on geospatial data and services has been widely reported, including in the Hindu Times and TechCrunch. This new development evoked positive responses from long-time Indian OpenStreetMappers Arun Ganesh (planemad) and Sajjad Anwar (geohacker). Together with Pranesh Prakash, Sajjad provided a more detailed perspective in an article for CNN News18.

Releases

• QGIS 3.18, with new highlights and features such as native point cloud support, is now available.

OSM in the media

• Bloomberg CityLab used a rather sensationalist title, ‘Inside the “Wikipedia of Maps”, Tensions Grow Over Corporate Influence’, to report on corporate involvement in mapping in OpenStreetMap.
• Jonah Adkins , of Stamen, details their design and cartographic decisions behind the newly launched Facebook Global Map project, which is based on OSM data.

Other “geo” things

• A group of researchers have developed new techniques for simulating the deep history of the Earth’s surface. You can watch an animation of the last billion years in Alan Collin’s tweet. In a journal paper Andrew S. Merdith and colleagues describe their method, which allows for the movement of complete tectonic plates, rather than continental landmasses, to be reconstructed for the past billion years. The advantage of modelling the entire plate rather than just continental drift is that the properties of plate boundaries can be properly taken into account.
• Want to view Apple Maps, but you only have a Windows or Android device? All is explained by How to Geek.
• The Economic Times reported on a new partnership between the ISRO (the Indian space agency) and digital map provider MapmyIndia to provide new made-in-India geospatial solutions.
• Places in Japan with loud gossiping adults and boisterously noisy children are on the Dorozoku map, a country otherwise known for its quiet.
• Here is a new attempt to create the ‘Most Accurate Flat World Map’, with a division of the projection into front and back sides of the earth.
• Natural Earth released additional ‘point-of-view’ versions of the country theme to accommodate places like China and India, which mandate by law the use of particular boundaries that don’t always reflect reality, in published maps.
• The latest news from ArcGIS: a new OpenStreetMap Daylight map (beta) is being further developed with regular updates and releases.

About us

• weeklyOSM contributor Rogehm has published his interview with Lamine Ndiaye, who uploaded changeset 10⁸.

Mapping

• TheSvawu has tweaked “osm-in-realtime” so that it starts at 99,999,800, so that you can look again at the mapping activities near changeset 100,000,000. Interesting to see who was mapping around the magic number. It is also interesting to read the comments on some of the changesets
  

  Changeset	Mapper	Comments
  ..99,999,991	LucGommans	“Greetings from the Netherlands!”
  ..99,999,999	AE35	“99999999 is definitely a cooler number than 100000000”
  100,000,000	Lamine Ndiaye	mapper of changeset 10⁸
  100,000,001	MikeN	“Congrats on the 100,000,000th changeset!!! (Changeset 0 doesn’t exist anyway)”
  100,000,040	overflorian	Advertising for a good cause in a congratulatory comment is always possible
  100,000,058	Allison P	“added house (hello 100 million!!!)”
  100,000,176	Steve	We were 52 seconds away from what would have been the best coincidence
  100.001.328	Stereo	Congrats to the 100 Million Village

• We just had the 100 millionth changeset and at the same time the 8,458,919,620th node and the 910,977,970th way. Here you can see when 110 million changesets, 10 billion nodes and 1 billion ways are to be expected.
• As directed by OSM’s Organised Editing Guidelines, the Tallinn-based company Bolt is now writing to communities in a number of OSM countries about where they are planning to map. Reactions have included ‘our roads are already complete’ and ‘contributions in newly-built suburban areas might be helpful’. Bolt were originally brought to the attention of OSM’s Data Working Group, not because of poor mapping, but because a local OSM community (in Sweden) didn’t know who they were, because the initial changesets and user account details did not say – a clear indication of the advantage to the company doing the mapping of following the guidelines.
• Last week we reported on the longest highway on OSM. No sooner had we done so than Christoph Hormann (imagico) added a correction to the thread ‘you are not even close’.
• Kevin Karson (user karsonkevin2) has been extending the mapping of athletics tracks in Iowa, and produced a visualisation showing every track in its correct orientation. Click on a track to see it on OSM.
• Stephanie May has been mapping parklets in Seattle, as they are particularly valuable during these Corona times. They opted for leisure=outdoor_seating and outdoor_seating=parklet as the main tag, but in the San Francisco Bay area leisure=parklet (not documented) has been used, so they are seeking further views on the matter. (A similar discussion occurred recently on the UK mailing list, which threw another option into the mix: leisure=garden.)
• The following proposals are awaiting comments:
  • historic=tomb, proposed by Martin Koppenhoefer, to provide a tag for all kind of tombs: mausoleums, pyramids, simple tombs, prehistoric tombs, tumuli, rock-cut tombs.
  • nudism=designated, proposed by Tamas Rell, for a beach/resort/etc. which is officially designated as nudist, but nudity is not obligatory. Basically an official public nude beach.
• Voting has ended for the following proposals:
  • historic=ogham_stone was successful with 14 votes for, 1 votes against, and 1 abstention.

Community

• Luc Gommans provides a formidably detailed analysis of how mappers tried to game being the person to make the milestone changeset of 100,000,000 (which we featured last week). Clearly, this event brought out the inner geek in many of us.
• Using data from the recent OSMF Community Survey, Jennings Anderson posted an analysis of per-country editing activity since 2020. The distribution of local/non-local mappers per country and the number of edits per user vary greatly among countries. The analysis notebook is available online.
• Have a look at the International Women’s Day 2021 events! The American Red Cross and Missing Maps are hosting the International Women’s Day Mapathon 2021.
• Mike Collinson gave an excellent summary of ‘how we got to where we are’ with highway=track and surface=*, on the Australian mailing list.

OpenStreetMap Foundation

• On 10 and 11 March (Wednesday and Thursday) OSMF Chair Allan Mustard will present a series of three BigBlueButton video conferences open to the OSM community to answer questions about the survey results. The sessions will be at noon UTC and 20:00 UTC on 10 March, and 04:00 UTC on 11 March (these correspond to 07:00, 15:00, and 23:00 EST). He will present some summaries of the data in graphical form, then take questions. He will use his BigBlueButton home room.Allan also plans to open an instance of Microsoft Translator and will share the access code for the instance at the start of the presentation, so that anybody with Microsoft Translator’s app (on desktop, notebook, tablet, or smart phone) can follow the presentation in the language of their choosing. He will also use the PowerPoint 365 speech to text feature to offer English subtitles. Anyone planning to view the video conference should download the Microsoft Translator app in advance and become familiar with it first.
• Christoph Hormann shared > his insight about a Meeting of the OSMF Board with the Advisory Board, Local Chapter Members and an ESRI representative, held on 24 February.
• Michal Migurski prepared two diary entries with maps that illustrate the results of the OSMF Community Survey. The first post focuses on mappers and survey respondents, while the second is dedicated to Board priorities and technology policies.
• Giuseppe Puntofisso, the head of NHSX (AI skunkworks for the NHS) is experiencing difficulty contacting the OSMF Legal working group.

Local chapter news

• Nathalie Sidibe announced, on the Talk-africa mailing list, that OSM Mali is now officially registered as ‘Association OpenStreetMap Mali’.

Events

• The State of the Map Africa (SotM Africa) is regional conference, held every other year, that celebrates the culture of open mapping, open data, GIS, and its impact across Africa. SotM Africa 2021 is scheduled for 19 to 21 November and will take place in Nairobi, Kenya. The conference’s theme will be ‘Leaving no one behind: Emerging from a global pandemic’.
• An online Torino mapping party will be held > this Wednesday 10 March from 15:30 to 18:30 CET. The activity is jointly organised by 5T and ITHACA, and will take place completely online. This year’s theme will be ‘Collaborative mapping for better living’, to teach new digital tools to everyone with the aim of better understanding the territory we live in.

Maps

• The latest post from HeiGIT looks at the completeness of OpenStreetMap railway network data for a specific city, Prague, and its development over time. Furthermore, the article animates the development of the railway network mapping with instructions so you can learn how to make one yourself.
• Hell freezes over: UK’s Ordnance Survey has launched an OSM-based app in Australia.

Open Data

• Last summer Ivan Gayton explained eloquently how the use of proprietary software reinforces racial and postcolonial inequalities. High costs, and erroneous cost-benefit analyses associated with proprietary tools, mean that it is mainly people from Western countries who acquire expertise. People from affected areas therefore benefit much more from the use of free software. Imma Mwanja recommended the article in the course of the webinar ‘Colonialism in Open Data and Mapping’.
• The Swiss OpenStreetMap association (SOSM) welcomed swisstopo, the national mapping agency, to the open data world. The blog post explains some caveats about the licensing of swisstopo data in the context of OSM.

Licences

• Nuno Miguel Azevedo reported in a tweet that the Angra do Heroísmo City Council, in the Azores, recently launched the app MyAngra, available for Android and iOS. It is a tool for locating the main points of interest in the municipality. What’s missing is the proper licensing and attribution of the base map to OpenStreetMap.

Software

• Nominatim, the open-source geocoding tool based on OpenStreetMap data, introduced a command-line version leading to many changes such as much less fiddling with PHP scripts.
• The free software Offroad is an offline map viewer for the desktop. It is based on OsmAnd.

Programming

• In episode 61 of the Geomob Podcast, Ed Freyfogle talks with Sam Crawford, developer of Trail Router, an OSM-based route planner for runners.
• You can read a dialogue-like tutorial between Pierre Béland and Jean-Marc Viglino, the author of the ol-ext OpenLayers Extension tools, about the dynamic addition of layers to an OpenLayers Map using WMS Servers catalogue queries.You can test yourself with the WMS Capabilities example providing your own GetCapabilities request like this for OSM-France https://wms.openstreetmap.fr/wms?service=wms&version=1.3.0&request=GetCapabilities (For security reasons, OpenLayers accepts cross-origin requests only if authorised by the WMS Server with the header [Access-Control-Allow-Origin, *].)

Releases

• Version 3.0 of Nominatim-UI adds theming and other features which make the user interface independent from the standard installation on openstreetmap.org servers.

Did you know …

• … the OSM principle that you can use any meaningful tag you want? Sometimes it’s helpful to coordinate with other community members, but that’s not a requirement. Think of a meaningful tag, make sure it doesn’t clash with or contradict tags already in use, document it on the wiki, move out into the world and map!
• … that the UN Mappers run weekly mapathons? Two hours with them to learn, discuss, and map together, supporting UN peacekeeping missions in Africa. Each week an in-depth look at a different topic! You can register here.
• … the World’s Population map in 3D, created by Matt Daniels?

OSM in the media

• The privacy-oriented Italian website Le Alternative updated its post > about alternatives to Google Maps, which prominently features OSM-related tools.

• A historic 19th century house was moved, by road, in San Francisco. Needless to say care was taken to move the equivalent element on OSM. An article in The Guardian provides some more information on the history of moving houses in this way.
• Kontur released its Global Fires viewer, allowing you to see a year of fire data on a mobile device and find places nearby with clean air to escape to during the wildfire season. They customised Unfolded Map SDK and pulled in the fire event feed to visualise the wildfire patterns. Users can see the state of air quality for the past three days to find a spot clear from smoke pollution.
• Scottish geospatial firm thinkWhere have won a contract as part of the Open Maps for Europe project, led by EuroGeographics, a not-for-profit umbrella company representing national mapping and cadastral agencies.

Mapping campaigns

• Two schools in Portugal and Romania, both members of the Humanitarian OpenStreetMap Erasmus+ project, are carrying out a three-day mapathon together with UN Mappers.Starting on Monday 22 March ‘remaining works’ in Terceira are on the programme. On Tuesday and Wednesday, work will be carried out on a previously unpublished project of the UN Mappers. It looks like they want us to support the blue helmets of the MINUSMA-Peacekeeping mission in Mali (which includes the Romanian blue helmets).

Mapping

• User Supaplex030 has performed a detailed analysis of parking spaces (both on- and off-street) in the Berlin suburb of Neukölln. This necessitated detailed mapping in OSM of parking, and other things which affect availability of parking places (driveways) along the street.
• Simon Poole showed how minor geometry errors can creep into maps, even those from major providers.
• Benjamin Herfort describes in part 4 of ‘How to monitor humanitarian mapping in the HOT Tasking Manager’ the global statistics available – such as the number of projects, participants, buildings, roads, etc. – and the various possibilities to dig into these metadata.
• Paul The Archivist explained how he approaches the detailed 3D mapping of a town centre: in this case Hertford, north of London. There are useful tips on workflows and being selective about which buildings are mapped in detail.
• A request has been made for comments on the following proposal:
  • ref:find_a_grave=* linking to the FindAGrave identifier in order to provide more information about the person while limiting the data volume occupied on OpenStreetMap.
• Voting is underway for the following proposals:
  • place_of_worship=holy_well for places where Catholics, in countries like Ireland, celebrate the well’s patron saint with a mass once a year, collect ‘holy water’ and leave votive offerings (till Thursday 25 March)
  • emergency=lifeguard to indicate where a lifeguard will be while they are on duty (till Tuesday 30 March).
• The area around the village featured in changeset 100 million is now densely mapped.

Community

• Bert -Araali- Van Opstal complained about the behaviour of some members in the Discord channel devoted to OSM.
• Pascal Neis has previewed some proposed new #map view filters for the ‘Latest OpenStreetMap Edits per Tile’ in his resultmaps. Features like OAuth, login for saving the filters, list of friends and so on are not yet implemented. Pascal is asking for feedback.

Imports

• It is proposed to import building outlines from official data in Norway. The timescale from proposal to starting the import is somewhat ambitious, being only two weeks.
• Abdullah Abdulrhman reported the completion of importing governorates’ administrative boundaries in Saudi Arabia to OSM and asks the community to review this work to make sure everything is OK.

Local chapter news

• OSGeo Oceania announced the opening of its Microgrants program. The program will support local activities linked to open geospatial software or data with up to $250 AUD.
• OpenStreetMap Belgium’s Mapper of the Month for March is Gustavo Soares (PlayzinhoAgro).

Events

• The call for sessions (talks, workshops, and discussion panels) is now open for State of the Map 2021, which, as last year, will be held online. The deadline for proposals is Sunday 4 April.

Humanitarian OSM

• HOT presented a map of COVID-19 response remote mapping activity around the world.
• HOT also presented a story map of their disaster actions in 2020. The context of the actions is presented along with global contributor statistics.

Maps

• Amateur radio operators are keen to discover new technologies and this includes mapping. Many applications make use of OSM, such as the positional tracking service APRS with its APRS-Map, which displays the distribution of KiwiSDR receivers, or the popular Repeater Map, which shows the position of amateur radio repeater stations. However, amateur radio operators are not just consumers of but also contributors to OSM. You can find them everywhere, writing for weeklyOSM, just mapping, or on the OSMF board. So it is not surprising that there are amateur radio functions in OSM community projects like the optional QTH locator layer, which is a special geographic co-ordinate system, on the OpenTopoMap.

Software

• Roland Olbricht was delighted to announce the first contribution by an Overpass user other than himself to the Overpass blog. Antoine Riche provided an in-depth look at how to use some of Overpass’s new features to count roundabouts in France.
• Via Epona is an app aimed at helping you to discover the French terroirs (traditional farming regions) by bicycle. Its first public version is coming out on Sunday 21 March, the second day of spring.
• qeef has refactored ‘Divide and map. Now.’, a tool for collaborative mapping. In his current diary entry he summarised how the clients now look.

Programming

• OpenStreetMap has once again been accepted as a mentoring organisation for Google Summer of Code. Now there is a search for projects and people to mentor them. The current list is here.

Did you know …

• … paleochannels (as recently discussed on the tagging mailing list) are former courses of a river within a floodplain. Changes in some rivers, such as the Mississippi, have been intensively documented, while others are plainly visible on aerial imagery.
• … there are services that let you compare maps from different sources? One of these is CompareMaps.drona.ro, which offers an easy comparison of Google Maps, OpenStreetMap, Bing Maps, and HERE Maps.
• … of the many ways to get in touch with the OSM community?
  

  Where can I get help, where can I find people to talk to?

About us

• We have received two comments regarding issue #556. Here are some clarifications on these subjects:
  • We reported Bert -Araali- Van Opstal’s complaint about some behaviour on Discord. Mateusz Konieczny, leader of the ‘OSM World’ moderators team on Discord (account needed) noted that the nine moderators from around the world have taken this complaint seriously. However, after hours of searching through the logs for the abusive comments described by Bert they were unable to find them. They reminded users that anyone on the discussion groups can contact the moderators directly (message @ModMail) to report abusive, racist, or insulting language.
  • Our statement that there is a radio amateur on the current OSMF board is not correct. While we have learnt that one can find amateur radio operators actively contributing to the Overpass API, helping in the OSMF MWG, as founders of projects such as OpenRailwayMap, and in many other roles, we also learnt that there isn’t one on the OSMF board.

  As the weeklyOSM volunteer writers and editors cannot systematically go through all discussion and forum threads or social media posts, it is up to you to follow the links, read further, form your own opinions, and participate in the discussions. You can also reach us easily if you would like report and contribute to brief summaries of discussions to contribute to a better weeklyOSM.

  Let’s have fun and maintain a respectful and enjoyable environment!

Mapping campaigns

• Marcel Reinmuth, from the Heidelberg University’s GIScience Research Group, blogged about the development of OSM healthcare related objects in India. He noted a significant increase in the use of healthcare related tags during 2020. They also looked at complementing tags such as name (used on 98 percent of all healthcare objects), healthcare speciality (1.72 percent), beds (0.08 percent) and many others. However, they conclude that the majority of information for healthcare related objects beyond the amenity tag are still missing. The geographical distribution of the objects and the tags used for specification indicate correlation with urban areas.

Mapping

• DenisJu called on everyone who is on the road in Albania to take and share mobile phone images in Mapillary. He is specifically interested in images of the Albanian region Shkoder County, where he is keen to update OSM based on the donated images.
• Joost Schouppe wrote about his first MapComplete theme: a tool for campers to highlight, improve and add official overnight camping spots and sanitary dump stations. MapComplete is generic and the article invites you to help build more themes.
• Requests have been made for comments on the following proposals:
  • man_made=utility_pole this aims to review and complete man_made=utility_pole with existing utility=* for poles intended for other activities than power transmission and distribution.
  • highway=busway to replace highway=service + access=no + bus=designated + service=busway.

Community

• M. Sevilla-Callejo showed a video about how to easily share a location from the OSM homepage.
• OpenCage published an interview with Iman Moghimi about OpenStreetMap in Iran.
• On 20th March mappers in Japan celebrated the 50th session of Mappy Hour Japan > , which has been held every Saturday night, on Slack, since the spring of 2020.

Imports

• Cascafico Giovanni announced a plan, as documented in the OSM wiki, to import a dataset of mobile phone communication towers, provided by the Italian region Friuli Venezia Giulia.

Education

• On the Geography of the Landesbildungsserver Baden-Württemberg portal you can find a lot of information about geo-topics. In the chapter Interactive Maps > you can find some information about the free world map OSM. It’s worth a browse.
• Moritz Schott, Yair Ginberger, Sven Lautenbach and Alexander Zipf, from the universities of Heidelberg and Jerusalem, have published a framework to analyse online community member activity. Participants of 94 mapathons in OSM were analysed with regard to changes in their mapping behaviour. It was shown that advanced mappers are rarely influenced by mapathons. In contrast, newcomers who attended a remote mapping event in many cases did not stick to the project and ended up concentrating on creating new data with lower quality but high quantity in places foreign to their home region; newcomers who attended a field mapping event updated and enhanced existing local data with high accuracy.

Maps

• Daniel Capilla (dcapillae) presents > an interactive map with the layout and known remains of the ancient medieval wall of Malaga. The map also includes the hypothetical layout of the walled enclosures that protected its suburbs and the location of the city gates. Unfortunately the menu and the explanations are only available in Spanish.
• Equal Street Names is now also online for Leipzig. The map is updated every Thursday and shows, after the respective street has been linked to a Wikidata entry, whether it is named after a man or a woman.

Open Data

• Craig Taylor updated one of his projects, making ‘data flowers’ from ONS commuter data and OSM networks.
• Six authors from the Center for Digital Safety & Security, AIT Austrian Institute of Technology GmbH, published (paywalled) a paper titled ‘Packet Error Rate Based Validation Method for an OpenStreetMap Geometry-Based Channel Model’. In their work they focus on validating OSM geometries based on a stochastic channel model, which they then compare with time-variant power delay profile and Doppler spectral density obtained from a measurement campaign. The introduction mentions that OSM data shows minor differences to the measured data. Unfortunately the full report is behind a paywall.
• In his user diary, Tobias (@tordans) published > an interview with Alex (@Supaplex030) about his approach to ‘refining’ an open dataset, available at the district level, using OSM and other building information (we reported earlier). The result is statistical data on the number of residents per house and their car ownership.

Did you know …

• … that there is an Overpass API Blog? Roland Olbricht, developer of the Overpass API, describes new features of the Overpass QL syntax through clear and fully explained examples. Roland welcomes contributions such as that by Antoine Riche which we reported last week. So feel free to propose an article on GitHub.

OSM in the media

• Clubic, a French webzine, reported > on the 3-year collaboration between main public electricity distribution network operator Enedis and OpenStreetMap France, which we have already covered.

Mapping campaigns

• ‘The map is power’. For over 50 years, the Waorani of Ecuador have fought the exploitation of their traditional territories. This year, the Waorani won a historic legal victory, in part due to extensive participatory mapping efforts undertaken with partners Amazon Frontlines and Digital Democracy. Alex Yule was lucky enough to witness their victory and the power of community mapping efforts first hand.
• The second UK Quarterly Project of 2021 is ‘Buildings‘. The aim is to trace buildings missing from the map, follow up on construction sites and new builds, or to add more details to already mapped buildings.

Mapping

• The issue of multi-school campuses came up again on the tagging mailing list. This topic has been discussed several times before: for instance, on talk-gb in January 2016 and on the tagging mailing list in April 2019.
• Simon Poole reports that there some updates to his QA tools relating to addresses and road names in Switzerland.
• A young Moroccan developer has single-handedly mapped his home town’s entire public transport network, and created a new app based on Trufi Core.
• Reddit user bompe4 wrote on the OSM subreddit about being confronted by an angry resident whilst surveying. The experience exacerbated existing problems with anxiety. The discussion is well worth reading for practical advice on a real, if relatively rare, problem for mappers.
• Florian Lohoff has extended his address and routing evaluation to Brandenburg and Schleswig-Holstein. He explains > that routing can end far from the destination if access roads are incorrectly mapped.
• The following proposals are open for comments:
  • was:place_of_worship=mass_rock for a mass rock which is a rock used as an altar where (Catholic) mass was said during Penal times in Ireland and which was usually used as an altar.
  • landuse=education for grounds with multiple educational amenities (e.g. kindergarten, school) in place of using one or more amenity nodes inside an amenity area.
  • amenity=clubhouse for a location used and operated by a club.
  • railway:signal:*:shape allowing mappers to map the visual appearance of railway signals that have the same meaning.
  • Discourage the use of railway=preserved and use railway:preserved=yes instead.
• Voting is underway for:
  • highway=busway for dedicated roadways for bus rapid transit systems (till Wednesday 14 April).

Community

• Brian Sperlongano is proposing to clean up the tagging of rivers and streams in Canada. Several users are supportive of the idea, and some point out the need to check geometries and duplicate polygons as well as the tagging.
• YouthMappers announced a new partnership with the US American Geographical Society. Through this partnership, Courtney Clark will become the Everywhere She Maps Program Director.
• Thomas (SunCobalt) is thinking about how to analyse the roughness of tone in changeset comments compared to that on the OSM talk mail lists. As always, Pascal Neis has a tool for extracting the respective texts.
• Jennings Anderson published a must-read article about paid mapping in OSM. He breaks down the paid editing in his analysis into the countries affected and the corporations making these edits, illustrates the history of paid mapping, and sets out the proportions of paid edits into relation to overall edits in the individual countries. The analysis contains many nice visualisations of the development of this trend. This report is an update of Jennings’s 2019 paper which we reported last year.

Imports

• The OSM community in Sweden is planning a manual import, or rather a coordinated mapping effort, to improve the quality of OSM in Sweden. This effort has already been announced on the import mailing list and more input from interested users is welcome. Further details are laid out on the OSM wiki.

Local chapter news

• In Episode 67 of the Geomob Podcast Ed Freyfogle interviews long-time OSM India contributor Sajjad Anwar about the recent changes in Indian mapping regulations and what this might mean for OpenStreetMap in India.
• OpenStreetMap Belgium’s Mapper of the Month for April is Alouette955, an enthusiastic cyclist and contributor from Montreal.
• OSM UK has submitted a midterm report for their project focusing on leaflets to promote OSM for which the project has received a microgrant.

OSM research

• GIScienceHD has presented the first version of the ohsome-py Python package. ohsome-py helps you extract and analyse OpenStreetMap history data using the ohsome API and Python. It handles queries to the ohsome API and converts its responses to Pandas or GeoPandas data frames to facilitate easy data handling and analysis. The project is still in an early stage, so there might be changes to the package in the future. To learn how ohsome-py works get started with the tutorial.
• Yair Grinberger, Moritz Schott, Martin Raifer and Alexander Zipf have published a report on the impact of of organised mapping events that can produce massive addition of data to OSM in a short period. The study points to the different perspectives of organisations and their unequal geographic distribution; region-specific types of additions; and the intense activities that follow (see this map of the results). This requires consideration when using OpenStreetMap data and analysing their quality.

Humanitarian OSM

• MapUganda has been mapping Ugandan border towns to help local health responders monitor potential avenues for COVID-19 transmission.
• This month, the HOT Philippines team completed the required fieldwork for the PhilAWARE project and is now presenting output maps to stakeholders.
• Public Lab Mongolia has used support from a HOT Rapid Response Microgrant to assemble a diverse team of mappers from across Mongolia to map health, service, and infrastructure sites relevant to COVID-19 responses.

Maps

• HeiGIT has visualised, on different maps:
  • travel times to health facilities and population coverage at different scales for a variety of countries, and
  • travel times to immunisation centres within one’s own state in Germany.

Open Data

• Drone pilot Michael Jones has filed a lawsuit against the North Carolina Board of Surveyors after it threatened him with gaol time and fines for taking aerial photos.

Software

• Mateusz Konieczny published an online tool that generates SVG maps from OSM data. This tool is the first prototype for the microgrant project ‘Tactile maps for blind or visually impaired children’. Feedback is welcome!
• Michel, from the Locus team, presented ‘Locus Map 4’ as a brand new app that offers all the basic map functions for free.
• Yuri Astrakhan called on Mapbox to transfer control of some of their FOSS projects to community governance. The discussion continues in the comments of tilelive’s pull request #222 on GitHub.

Programming

• Following Stephan Knauss’s report of memory leak problems in his rendering chain after updating to the latest version of PostGIS (we reported earlier). Darafei, from PostGIS, redirected him to the trac.osgeo.org/postgis instance to report issues.

Did you know …

• … of the large variety of social media, messengers, and web services contact methods that can be tagged with contact:*?
• … about this handy cheat sheet of JOSM shortcuts?
• … there is an OSM contributor statistics page on the wiki?

OSM in the media

• Directions Magazine described how women’s geospatial perspectives bring new ways of thinking to mapping. Women’s Media Center captured Maliha Mohiuddin’s commitment to the YouthMappers Everywhere She Maps programme, while this interview with the Everywhere She Maps Regional Ambassadors shared Maliha’s and the other ambassadors’ takes on building an inclusive mapping community. YouthMappers is a global network of university student-led chapters at 260 universities across 57 countries.

Other “geo” things

• ‘Desert Networks‘ is a scientific research project funded by the European Research Council and hosted by the HiSoMA research center at Lyon (CNRS – French National Centre for Scientific Research). The project aims to study the physical, economic and social networks that linked together the Egyptian Eastern Desert, from the mid-second millennium BCE until the late third-early fourth century CE. Among the many research results, the website hosts an interactive map which makes it possible to search for sites by location, chronology and characteristics, with additional shapefiles available.
• OpenMap Development Tanzania and the UK Space Agency International Partnership Programme recently concluded the METEOR Project, generating disaster exposure data and models in two pilot countries – Tanzania and Nepal.
• MapBox announced improvements to imagery at many zoom levels, together with more recent data in many areas.
• After what3words, Maps Mania reports that what2figures reduces the need to remember three words, to pinpoint a geolocation, to just two numbers. Not sure where we’ve heard this idea before.
• #geoObserver reported > on a Google-based shelter and bivouac map. The map makers are seeking more shelters and hiking huts, along with photos and additional information, to add to their map. An overpass query of OSM data shows how many are currently missing.
• Geomob interviewed Tim Newman of the Ordnance Survey, the national mapping agency for Great Britain, in episode 66 in their regular series of podcasts. Topics touched on included geodesy, outdoor apps for consumers, and OS’s new app for Australia which includes OSM data (as we reported earlier).
• Cartapaname offers > a puzzle based on the 80 quartiers of Paris and explains their origin.
• Retromap shows you a number of historical map layers, including maps made by the Soviet Union in the 1980s.

Mapping campaigns

• In March, EqualStreetNames.Leipzig started to link the streets of Leipzig (Germany) in OSM with their namesakes’ Wikidata entries. The next project day is Sunday 25 April from 8:00 am UTC. If you want to participate in the online meeting and help to complete the tag landscape of Leipzig, please write to fey_kuehn@posteo.de for further information.
• OpenStreetMap US is calling for ideas and session proposals for MappingUSA, their virtual spring conference. Whether you’re new to OSM or have been a contributor since the beginning, they want to hear from you! Submit your proposal here. The deadline is Friday 23 April.

Mapping

• SwiftAddress is an application designed to be able to efficiently collect house numbers for OpenStreetMap. While available on GitHub, it’s planned to be released in app stores soon.
• April brings two international commemorative days that offer fun ideas for mapping. Earth Day on Thursday 22 April demonstrates support for environmental protection, and the less well-known International Day of Human Space Flight, which is 12 April, proclaimed by the United Nations in 2011, fifty years after Yuri Gagarin’s first human space flight. You can continue to support OSM by using earth observation imagery.
• The MapRoulette blog has a new guest post about mapping reservoirs in the United States, written by Brian Spergolano. Many reservoirs in the US were imported years ago as nodes. This challenge asks mappers to add missing reservoirs as polygons, remove those that no longer exist, and generally help improve water mapping in the USA. The challenge is also featured at MapRoulette.
• Six members of OSM Mauritania have GPS traced the entire public transport network in the capital, Nouakchott, including informal transit. The result: the first interactive map for the city’s bus and taxi routes.
• Requests have been made for comments on the following proposals:
  • Facade garden – for tagging miniature gardens built against a building facade in an urban area with garden:type=facade_garden
  • Fossil – for tagging a fossil, either naturally occurring, as a part of a construction, or as a fixed artefact, with natural=fossil
• The proposal to replace landuse=forest by boundary=forestry is open for voting until Tuesday 20 April. The turnout is already much higher than usual (109 votes at the time of publication) and the results so far indicate that the topic belongs to the class of the more controversial issues in OSM.
• Voting has ended for the following proposals:
  • trailblazed=poles;cairns was approved with 22 votes for, 0 votes against, and 3 abstentions.
  • highway=busway was approved with 36 votes for, 5 votes against, and 1 abstention.

Imports

• After weeks of discussion, elaboration and the presentation of an import proposal, the Portuguese OpenStreetMap group will start importing national addresses based on the free use database of the National Statistics Institute. For more information, consult the project’s wiki page > or the group’s official channel on Telegram.

Local chapter news

• OpenStreetMap US announced Mapping USA, a free virtual event that will take place on 20 to 22 May. Mapping USA will include an informal Mappy Hour on Thursday, a half day of talks on Friday, and a day of workshops, birds of a feather sessions and mapathons on Saturday.
• Mappers from the Poitou-Charentes region, in France, will hold an online meeting on Wednesday 21 April at 6:30 pm.

Education

• HeiGIT and German Red Cross have published > further training material for mapathons.

OSM research

• In a YouTube video, Reeniz shows us the numerical evolution of mapped buildings in Latin American countries from 2007 to today.

Humanitarian OSM

• A UK contributor used MapUganda to create Humanitarian Mapping tasks for Merthyr Tidfil, Wales in the UK and justified their changes by citing the most alarming COVID-19 metrics in the UK. UK contributors were not consulted prior to these actions and some contributors are upset by the lack of communication and transparency, and poor mapping quality, such as retagging residential roads as motorways (example) (see discussion). Richard Fairhurst asked that the mapping activity be paused. He doubts the rationale of the task because the local Director of Public Health should have access to authoritative building footprints. It appears the projects have now been removed from the tasking manager.
• HOT’s Community Support Manager, Sophie Mower, shared feedback received from microgrant applicants and community members on the new mentorship program for applicants, which helped them to strengthen and refine their applications.

Maps

• [1] The overview map of the EqualStreetNames project shows the 17 cities currently participating, from Belgium (9), Germany (5), the Netherlands (2), and Serbia (1). Each of the city street maps shows, in distinguishable colours, the gender of the person the street is named after, and the Wikipedia and Wikidata links. The GitHub repository explains in detail how to create one for a city of your choice.
• WOM, mobile and Internet provider in Colombia, has an OSM-based map that shows the coverage and quality of its G3 and LTE network.
• OpenPoiMap (formerly Taglocator) is a web application, created by Marc Zoutendijk, that helps you find various tags of interest, also called points of interest, on OpenStreetMap.

Software

• Mishari, a moderator of the Thai OSM forum, had a very positive first experience of mapping with StreetComplete. They ask if people are interested in a localisation hackathon to provide a Thai translation for the app.
• Foto-Entwerter is a tool, created by Michael Reichert, to black out faces and number (licence) plates from a large number of photos in a manual but efficient way for a large number of photos. Especially useful to avoid leaking personal information when uploading pictures.

Did you know …

• … if you feel bored during the lockdown, ImproveOsm can help by pointing to probable missing features for you to map? The tool exists both as a plug-in for JOSM and as an iD layer.
• … the German OSM server hosts a map that displays the values of opening_hours in a pleasing, human-readable way? It also allows the user to switch to more uncommon tags such as opening_hours:kitchen, smoking_hours, and collection_times.

Other “geo” things

• Sofia Moutinho interviewed Carlos Doviaza, a young mapper making maps to help Panama’s indigenous communities deal with various issues, including the ongoing COVID-19 pandemic.
• The district committee from the Munich suburb of Berg am Laim, Germany, received > a refusal for ‘organisational and financial reasons’ from the city’s map application team regarding the addition of public benches (the required data is not currently available in a digital form) .
• The Africa GeoPortal tweeted an introduction to the NigeriaGeoPortal. The portal provides a lot of CC-BY licensed datasets, with OSM as a basemap.
• French archaeologists have uncovered a stone with 4,000-year-old etchings they believe may be the oldest three-dimensional map found in Europe. The engravings on the Saint-Bélec Slab resemble topographical features including hills and a river network with a match rate of 80% along a 29 km stretch of the L’Odet.

Mapping

• Edoardo Neerhut has written a post on the Mapillary blog looking at the quality of pedestrian data in OpenStreetMap. Five cities with distinct characteristics were analysed to see how closely OpenStreetMap matches the reality on the ground.
• User mahdi1234 has published a short article on how to determine, with simple shell commands, how many post boxes, tracks, or steps one has mapped.
• The local OSM community in Penza, Russia, has managed to map most of their building outlines and addresses in just a few weeks. The number of buildings with addresses rose from 8.5 to 26.7 thousand (+214%). The results and the progress are visualised in Kachkaev’s OSM diary.
• Frederik Ramm has seen changeset comments consisting only of hashtags and reminded mappers of the need to write good changeset comments.
• Requests have been made for comments on the following proposals:
  • Light electric vehicles to define a set of tags to map restrictions associated with a range of new types of vehicles.
  • After Kai Poppe had proposed just ‘discouraging’ the use of railway=preserved, the most relevant comments hinted at using the more definite term ‘deprecating’. The proposal has been renamed and is still open for comments. The proposal was explicitly written to reflect the current state of tagging, where railway:preserved=yes is used more frequently. One very adamant point made in the discussion on the tagging mail list was that this proposed change would encourage excessive namespacing. The author therefore asks for more opinions on this specific matter – whether to keep the now more in-use tagging or to replace it with something completely different (such as railway:*+usage=preserved).
• Voting is underway for:
  • railway:signal:*:shape allowing mappers to map the visual appearance of railway signals that have the same meaning (till Friday 7 May).
  • amenity=clubhouse for a location used and operated by a club (till Wednesday 5 May).

Local chapter news

• Jess Beutler has stepped into the role of the first OSM US Program Director and is working on a part-time basis to strengthen and expand the impact and breadth of OSM US program offerings.

OSM research

• Franz-Benjamin Mocnik has written a paper investigating which aspects of OpenStreetMap data are consistent with Benford’s Law.

Humanitarian OSM

• Gloria Urrea, University of Colorado at Boulder, and Eunae Yoo, University of Tennessee, partnered with HOT to conduct research that has produced insights for HOT and the other organisations that use the Tasking Manager. Here, they summarise their research project, which examines the impact of users’ experience on project completion and retention.
• With a microgrant from HOT, the OSM Senegal community and Healthsites.io have been mapping hospitals and clinics across Senegal, aiding in the country’s COVID-19 response. (We reported earlier updates on this project in WN548, WN549 and WN552.)

Maps

• The School District of Philadelphia has launched an online dashboard to track COVID-19 cases within their schools’ student and staff populations.

Open Data

• Open data tree inventories can be uploaded to BaumCloud (the tree cloud). The tree registers of Berlin, Hamburg, Cologne, Frankfurt, Bonn, Leipzig, Chemnitz, Gelsenkirchen, Rostock, Krefeld, Troisdorf and Wesel are currently available for download.
• ILDA has made > a regional open data barometer for 24 Latin American countries, with Uruguay, Argentina, and Colombia being the more advanced in this aspect.
• Code for Kusatsu has obtained permission from Kusatsu City to trace from their aerial imagery. Instructions on how to do this have been written by user K_sakanoshita on the wiki page > .
• Stefan Lehmkühler (of the initiative ‘Changing Cities’ and direct candidate of the Green Party for the Berlin House of Representatives) has visualised > the Berlin police’s cycling accident data from 2018 and 2019 on a map and calculated how much the accidents cost over the two years per length of street. The data on the economic costs of an accident come from the Federal Highway Research Institute – the death of a person, for example, went into the statistics at EUR 1,121,888; for a minor injury, costs of EUR 4,959 were applied.

Software

• Greg announced the release of FHODOT, a new online tool that allows mappers to make efficient use of the rich source of open UK address and postcode data provided by the Food Standards Agency, particularly through JOSM. You can find more information in the readme on GitHub, where the source code is also published.
• If you want to use the Microsoft open source version of JDK to run JOSM on a X86 processor, then see Johnwhelan’s OSM Diary on how to download and install it on your system.
• MapComplete’s developer has announced that 500 unique contributors have made edits via MapComplete. Additionally, a small breakdown is given of which themes have proven to be popular in 2021. Peter invited the community to create their own theme on the platform.

Programming

• Stephan Knauss advised the dev discussion list that he had found and fixed a bug in the script ‘trim_osc.py’. Everyone who uses the script, for example via the switch2osm manual, is affected. Changed relations disappear from the database. A fresh import will be necessary.
• Stephan Knauss has found the cause of the memory leak in his rendering pipeline (we reported earlier). The cause is the PostgreSQL JIT feature, which has been active by default since version 12. In osm2pgsql, JIT is already dynamically disabled. In a GitHub issue, Stephan explains how you can identify and work around the problem.

Did you know …

• … OSM Relation Analyzer? This tool allows you to check relations and discover gaps in otherwise linear features.

OSM in the media

• German computer magazine c’t reported > (sign up required to read full article) on NUNAV’s apps with collaborative routing. In the article, graphmasters, the app’s developers, stress the usage of OSM.
• As we reported earlier, Code for Charlotteville has started an OSM-based project targeted to people with mobility issues. The project has attracted some attention from local media, which hopefully attracted some more volunteers.
• GIS Lounge published a podcast about OpenStreetMap as a community of communities.

Other “geo” things

• The page of the town of Bitche in France was blocked on Facebook because of its name.
• Digital Earth Africa reported on GeoMAD, a comprehensive new data service that combines an entire year’s worth of satellite observations into a handful of images. Combining Geomedian and Median Absolute Deviation (MAD) data, the service allows users to access annual cloud-free mosaics of the African landscape, as well as view statistical variations over time. The data is available annually from 2017 to 2020.
• Google has released Google Earth Timelapse, ‘The World’s Largest Video’. Using 24 million photos from two satellites, Google has created a time lapse view showing changes to the Earth since 1984 in 4D. It is 4.4 terapixels in size.
• The ABC News reported on the significant inaccuracies in Google Maps noticed by some mayors in outback Queensland, as well as how outdated the imagery in Google Street View is, both of which might discourage tourists from visiting.
• How to obtain, process, and visualise bathymetry data: an article about styling Ocean Depth Data in Mapbox Studio.

Mapping campaigns

• Florian Lainez announced > on the talk-fr list the launch of the May project, whose objective is to map medical analysis laboratories in France. All details are available on the site projetdumois.fr > .
• OpenStreetMap Ireland has worked on mapping Ireland’s historic boundaries over the past decade, through this project: http://townlands.ie. These boundaries are now very useful for developers to make new products using the 1911 Census, because it shares the same administrative boundaries. This will allow users to visualise the Census results from 110 years ago as if it was a modern Census. Another great win for OpenStreetMap.

Mapping

• Mapper nitinatsangsit asked in the Thailand Forum whether man_made=tower + tower:type=stupa is a suitable tagging for stupas. Meanwhile the tagging is in use in multiple other countries.
• Equalstreetnames has completed the categorisation of street names in Leipzig, Germany. Further analysis and considerations can rely on the interactive map and related statistics. Leipzig is the fifth German city for which this analysis has been done. The GitHub hosted project covers a further nine cities in Belgium and three in the Netherlands, as well as Bern, Switzerland and Belgrade, Serbia.
• Hungerburg has written > a blog post in which he contradicts the view that landuse=forest exclusively represents economically used forests. This is true in some regions of Germany, but on the other hand it is not internationally tenable.
• The German Outdoor-Forum > created an OSM-based shelter map with the help of uMap. Further shelters with photos and additional information can be posted in the forum; user Blauloke will transfer the information to OSM and onto the map.
• Flo Edelmann has revived wiki user Ajojo’s proposal about tagging whether a place offers and/or accepts reusable packaging. It is now open for comments again.

Community

• In his blog post, Bo Percival described the results from the design sprintathon and points out six problem areas. These start with high technical entry barriers, include the high variance in the quality of the collected data, and finish with the underestimation of the learning process required during mapping.
• OSM Zambia has completed their Facebook Community Impact Microgrant in which they mapped waste collection zones in the rapidly growing city of Lusaka to support the management of waste collection and disposal services.
• To improve field epidemiology and patient tracing in rural Uganda, HOT, with district health teams and community health workers, designed a community participatory mapping exercise across Kisoro and Zombo districts. Health workers were trained to use ODK, an open-source digital data collection application for smartphones.
• Four communities in Eastern and Southern Africa have been selected as recipients of the Facebook Community Impact Microgrant. Congratulations to The Shack Dwellers Federation of Namibia (social housing opportunities), OpenStreetMap Uganda (photo mapping with Mapillary), the Malawi OpenStreetMap community (refugee camp mapping), and the Center for Life Change and Development (mapping of facilities to fight gender-based violence).
• In honour of the 2021 International Women’s Day and Women’s History Month, the HOT Community Working Group (WG) organised two webinars: #ChooseToChallenge: Sexism and Misogyny in the Open Mapping Ecosystem. Arnalie Vicario shared the highlights.

OpenStreetMap Foundation

• FLOSSK have submitted an interim report for their microgrant project focused on mapping villages and settlements in Kosovo. They have led several online mapathons for students in locations across Kosovo with plans to expand activity in the coming months.
• Quincy Morgan and the OpenStreetMap Foundation’s Board made a joint statement on Quincy’s plan to leave the iD project. They will work together to choose and mentor an iD project successor.
• Based on requests from some OSMF working groups and the recommendation of the FOSS Policy Special Committee there is a now an OSM Nextcloud instance including OnlyOffice available for the community. It contains many collaboration tools for documents, calendars, and forms.
• Mateusz Konieczny has submitted a midterm report detailing his progress on a project for tactile maps. He has created tactile patterns and some initial tactile map designs.

Maps

• Street lamps are being equipped with sensors to help motorists find parking. The current status of parking in Düsseldorf is shown on an OpenStreetMap basemap.
• tom79 has investigated > various options for printing your own hiking maps. In addition to a number of geoportals, he also describes the printing of hiking maps using OSM data, including Maperitive, MOBAC and MyOSMatic.

Software

• User K_Sakanoshita announced > an upgrade to Town Walk Map Maker. In addition to being able to display steps, street lights, water tanks, etc., a QR code linking to Wikipedia and the ability to display an overview have also been added. K_Sakanoshita is also looking > for people to design icons for some other map features.
• Bryce Cogswell has issued a new beta of the iOS OSM editor, Go Map!! to TestFlight. One highlight of version 2.1.3 is the addition of a text recognition module for iOS 14-running devices, used to pre-fill opening_hours values.

Programming

• MapAction and HeiGIT are working together to carry out further research and development, teaching, outreach, and fundraising to support humanitarian mapping. Projects currently being planned include OSM analytics such as Humanitarian OSM Stats, and OSM data-quality assessments and improvements such as the ohsome quality analyst.
• Mapbox released a new tileset and style for bathymetry maps: developers can use these to add information about water depth on custom marine maps.
• Max Weber, of the YouTube channel Flutter Explained, talked about analysing Trufi Core, the basis of many public transport journey planner apps that use OSM.
