[1] The power of OpenStreetMap with links to things such as Wikidata shown by watmildon | © OpenStreetMap contributors.

Community

  • asciipip has detailed a method for naming trails in the Catoctin Mountain Park, by combining on-the-ground observations, such as coloured blazes marked on trees, with official trail information from the park’s website.
  • BingoBongo has been testing its in-house game engine, for realistic terrain and vegetation rendering, by integrating global geographic data from OpenStreetMap, high-resolution surface imagery from NASA’s BlueMarble, and elevation data from the Shuttle Radar Topography Mission.
  • The Trufi Association is celebrating their Volunteer of the Month, Anahi Gonzalez: a Mexican public-transport-mapping phenomenon.

OpenStreetMap Foundation

  • Grant Slater, of the OpenStreetMap Operations Team, has announced that OSM planet exports, including minutely, hourly, and daily diffs, are now being published through an Amazon Simple Notification Service. This move enables AWS users to automatically trigger workflows as soon as new OpenStreetMap data is released.

Local chapter news

  • Since late 2021, FOSSGIS e.V. has been curating a growing directory of companies and independent professionals offering support and services around Free and Open Source Software in the GIS sector, including OpenStreetMap and open geodata. The updated list is now available at dienstleister.fossgis.de, where new service providers can also register their businesses directly.

Events

  • A special opportunity is being offered by the organisers of the III Workshop on Participatory Mapping and Social Cartography – MPCS 2025, which will be held 100% online this August. Some projects from lusophone countries, presented at the Mapping Projects Exhibition, will be selected for publication as chapters in the second volume of the book series Case Studies in Collaborative and Participatory Mapping, to be released in early 2026 under the IVIDES publishing label. More information can be found in a post by the event’s chair, Dr Raquel Dezidério Souto.
  • In the latest episode of the Geomob Podcast, Ed interviewed Silas Toms, co-organiser of the recent GeoMeetup event in San Francisco. Silas discusses his geospatial tech background, the event’s success, and the resurgence of the local GeoMeetup scene. This episode also explored the growing role of AI, OpenStreetMap, and the importance of community and collaboration in the geospatial field.
  • Several upcoming GeoMob events have been announced, including Geomob Zürich, set for the evening of Thursday 15 May, at the Meta Zürich office; Geomob Netherlands, taking place in Utrecht on Thursday 22 May, at NOVI University of Applied Sciences; and Geomob Brussels, scheduled for Tuesday 3 June, at The Sister Cafe.
  • OpenCage GmbH’s Ed Freyfogle interviewed Juan Arellano and Andrés Gómez, from the Organising Committee of SotM Latam 2025, about the upcoming edition of the event in Medellin 4 to 6 September this year.
  • The OpenStreetMap US Mappy Hour will be held remotely (by Zoom) on Saturday 21 May 8:00-9:00PM ET. Hear from Bill Wetherholt, Professor at Frostburg State University, about how OpenStreetMap can be used in the classroom to teach Geography’s five themes. The OSM US Software Engineer, Jake Low, will also demonstrate OSMCha, a tool for monitoring changes made in OpenStreetMap.

OSM research

  • After analysing 746 mapping projects organised by the Humanitarian OpenStreetMap Team between December 2021 and November 2023, a group of researchers have found that humanitarian mapping largely relies on remote contributors performing basic tasks with minimal collaboration. The system, they concluded, is sustained primarily by the expertise of a small group of advanced mappers. While these projects generally succeed in achieving short-term mapping goals, the researchers noted they often fall short when it comes to building long-term, sustainable mapping capacity.

Maps

  • [1] Demonstrating the integration of OpenStreetMap with Wikidata, Matt Whilden has developed DecommissionedAircraftMap, which uses a daily bot to generate thumbnails from Wikidata entries and Overpass Ultra to retrieve geodata for displayed aircraft (historic=aircraft) from OSM.
  • Students in the Accounting Technician course at Jerónimo Emiliano de Andrade Secondary School, as part of Citizenship and Development, have made a map called Moedas do Mundo (Currencies of the World). This map shows the currencies of different places in the world, from ancient to current ones, and also a bit of their history. With this map, students were able to discover places in the world and some of their history. As it is always possible to improve, they will continue to do so next year.
  • LUN, together with the MasterZoo pet store chain, has launched an interactive map of dog walking areas in Kyiv. The initiative aims to support the development of a pet-friendly culture and responsible walking, and help create a barrier-free, comfortable environment for pet owners and their pets. The map already features over 200 locations: individual playgrounds, parks where walking is allowed, green areas and other places where you can walk your dog. Each location contains a brief description and notes on amenities, such as fencing, benches, litter bins, and training equipment for pets. You can read more about it in the accompanying blog post.

OSM in action

  • The Duitama Mapping Stars, a group of Colombian high school students, have digitised informal transport networks from East Africa, via Southeast Asia, to Latin America. The Trufi Association is raising money to send them to SotM Latam.
  • Gosfilmofond, a state film archive in Russia, has published a map with previously unpublished newsreels and archive photos linked to the places and dates of the events of the Second World War. The map lets you filter events by date, add your own photos, and uses OpenFreeMap tiles as the base layer.

Open Data

  • Michaël showed how to cross check between OSM elements IDs and their counterparts on Wikidata, using the R language.

Software

  • CoMaps, the emerging community-driven fork of Organic Maps, has released an updated version of its open letter addressed to Organic Maps stakeholders (we reported earlier). In the statement, the group reaffirmed its commitment to moving forward with the fork but emphasised that it remains open to ongoing negotiations with the original project’s leadership. A project on Codeberg and a Matrix chat have been created for the current working name ‘CoMaps’.
  • Tobias Zwick has announced that the StreetComplete project is receiving sponsorship from NLNet to support its full migration to a multiplatform app. The transition will leverage Kotlin Multiplatform and Compose Multiplatform for the user interface, paving the way for future releases on platforms beyond Android, including iOS and potentially Linux. Volunteer contributions are welcomed, particularly in areas such as migrating the UI to Jetpack Compose, improving the stability of MapLibre-Compose on iOS, and assisting with iOS development for those with the necessary expertise.
  • OpenAerialMap (OAM) V2 has been released, providing faster, more reliable access to satellite and drone imagery for humanitarian mapping. HOT and Development Seed are rebuilding OAM with a new STAC-based infrastructure and modern tools.
  • Panoramax tooted that, one year after version 3, the Panoramax viewer is undergoing a major update with version 4. A new look, better readability and a series of small details will make all the difference in using the programme. It’s being tested before being implemented. For more details, see the forum.

Programming

  • In response to feedback on his OpenStreetMap diary post and Mastodon toot (we reported earlier), Daniel has demonstrated the versatility of the Z-Curve + BIGMIN technique by developing a cloud-native static spatial index for 2D points. Leveraging the same Z-order space-filling curve and BIGMIN search space pruning, the solution enables users to host a single .parquet file, similar to ProtoMaps, as a spatial index that can be queried efficiently without relying on GeoParquet, R-Trees, or PostGIS.
  • TrickyFoxy demonstrated that you can run JOSM in a browser using CheerpJ, a tool for running graphical Java applications in browsers.

Did you know that …

  • … TrickyFoxy has introduced new functionality to OSMBuilding, enabling the platform to render building data from custom OpenStreetMap servers? This update allows individual buildings from alternative sources, such as OpenHistoricalMap and OpenGeoFiction, to be visualised, expanding the tool’s reach beyond the main OSM database, which was previously its only data source.

OSM in the media

  • The mapping of trees with OpenStreetMap and MapComplete was promoted by the Fluminense Federal University and also noted by the Federal Rural University of Rio de Janeiro. This initiative, a partnership between IVIDES.org and the YouthMappers chapters at UFRJ, UFRRJ, and UFF Campos, also included speakers at the Green Open Data Day 2025 evening session. The results are available on Wikimedia.

Other “geo” things

  • Alex Woodie, of Big Data Wire. has interviewed the Overture Maps Foundation CTO, Amy Rose, regarding the technical aspects of the foundation’s efforts to build a foundational reference map, something that other mapmakers around the world can build upon.
  • Deborah Pickett’s toot highlighting some confusing street names in Melbourne quickly sparked a wave of responses, with users sharing similar examples from around the globe.
  • Sean Gorman has experimented with a point-of-interest (POI) relocalisation method to improve the accuracy of POI data in the Overture database, by developing a mobile application that detects nearby POIs based on the user’s location. This enables users to select a POI and capture an image to enhance location precision. This effort sparked a discussion on Mastodon, noting that it is beneficial for improving commercial POI datasets, which are strong in coverage but weak in positional accuracy.

Why You Should Speak at SotM 2025

The State of the Map Call for Proposals deadline is approaching fast, and I know that feeling - staring at a blank page, wondering if your OSM experience is “conference-worthy.” Here’s the truth: if you’ve ever mapped something, solved a problem with OSM data, or helped someone learn about OpenStreetMap, you have a story worth sharing at State of the Map 2025!

The State of the Map Call for Proposals deadline is approaching fast, and I know that feeling - staring at a blank page, wondering if your OSM experience is “conference-worthy.” Here’s the truth: if you’ve ever mapped something, solved a problem with OSM data, or helped someone learn about OpenStreetMap, you have a story worth sharing at State of the Map 2025!

What to Present On?

I think that often, the biggest hurdle isn’t writing the proposal - it’s deciding what to propose.

Talk About What You Know: Your OSM Journey

The best State of the Map talks come from personal experience. Think about:

  • What tool or technique do you use that others might not know about?
  • How has your mapping journey evolved?
  • What do you know now that you wish you’d have known when starting?
Share What You Learned the Hard Way
  • What OSM challenges have you overcome or are struggling with?
  • The workflow you developed after trial and error
  • Technical challenges you solved in unexpected ways
  • Data quality issues specific to your area and how you addressed them
Consider Your Unique Perspective
  • What makes your OSM experience different?
  • The local mapping challenge is unique to your community/country/region
  • The community-building approach that finally worked
  • Creative uses of OSM data in your field and community

Remember: There are no rules and limits (I think 😄). Your proposal can cover ANY aspect of the OSM project - from personal stories and experiences to technical reviews and critiques. Maybe you’ve developed an innovative workflow, created a design breakthrough, or built something cool with OSM data. Perhaps you want to share your mapping process, showcase a real-world use case, or present insights from past projects. You could even explore futuristic ideas and what’s next for OpenStreetMap.

Once you’ve identified a potential topic, it’s time to shape it into a proposal by drafting an abstract and a session title.

Structure Your Abstract

Your abstract is a brief session description - other than this being what SotM attendees will read and make a decision when choosing among concurrent sessions, it’s also what the program committee reads, reviews, and scores. Think of it as a mini-story with four key parts:

  1. Start: What’s this about? Open with a statement that immediately tells what your talk covers.
  2. Problem: Why does this matter? Identify the challenge, pain point, or gap in knowledge your talk addresses. What struggle have you experienced or observed in the OSM community? Why should people care about this topic?
  3. Solution: What’s your unique angle? How did you approach this problem differently? What’s your innovative solution, fresh perspective, or unique insight? This is what sets your talk apart from others on similar topics.
  4. End: What will people learn? Be specific about what attendees will gain. Will they learn new techniques? Discover tools? Master a workflow? Leave with actionable insights? This helps attendees (and reviewers) understand the practical value of your session.

Choose Your Session Format

State of the Map offers various session formats to suit different topics and presentation styles.

  • Classic talks (20 minutes) are perfect for sharing specific projects, techniques, or experiences - this is the most common format and great for first-time speakers.
  • Extended talks (40 minutes) allow for deeper dives into complex topics or comprehensive case studies - choose this if your topic truly needs the extra time.
  • Workshops(60 minutes) are hands-on sessions where participants follow along on their devices, which is ideal for teaching practical skills or tools.
  • Panels(60 minutes) bring together multiple perspectives on hot topics - consider this format if you want to facilitate discussion rather than present alone.
  • There’s also an Academic Track(now OSM Science) for research-focused presentations on OSM, perfect for sharing scholarly work, data analysis, or research findings. Most topics work well as classic talks, so when in doubt, start there!

Tips for First-Time Speakers

  • Don’t Do It Alone!

Consider submitting a proposal with a fellow community member or colleague. You can co-present with someone you have collaborated with, a community, or an organisation that has done similar work.

Last year, I worked with Zacharia Muindi, Map Kibera, for an extended talk on a previous collaborative project!

Session Recording:A Replicable Model for OpenStreetMap Training Programs in High Schools

One of the best(at least for me) talks from last year’s conference was On the Ground by Jochen Topf and Frederik Ramm, watch it here.

  • Look Back for Inspiration!
    Check what previous accepted sessions looked like. Visit https://stateofthemap.org/ and review past conference programs for inspiration. The archives are full of talks from all experience levels.

  • Get feedback
    Ask someone from the community to review your proposal and/or idea.

  • Submit!
    Don’t overthink it. Done is better than perfect.

Common Concerns

If these doubts have crossed your mind, you’re not alone:

“I’m not an expert”

You don’t need to be! Fresh perspectives and beginner experiences are valuable.

“My topic seems too basic”

Introductory topics presented help countless newcomers. Your “obvious” knowledge might be someone else’s breakthrough or might spark new ideas.

“I’ve never spoken at a conference”

Your proposal is what counts, not your speaking experience.

“My English isn’t perfect”

The OSM community is global and understands that English isn’t everyone’s first language. Clear communication matters more than perfect grammar.

“I might not be able to travel to Manila”.

State of the Map 2025 is a hybrid event! You can present virtually via pre-recorded video (with live Q&A), participate in virtual panels, and connect with the global community online. Additionally, travel grants are available to help you attend in person; apply here. Distance shouldn’t stop you from sharing your story.

Remember: Your Story Matters

The OpenStreetMap project thrives on diverse voices and experiences. Whether you’re mapping sidewalks in your neighborhood or building complex routing algorithms, your contribution to the conversation is valuable. Panel at SotM 2024 Photo from SotM 2024, CC BY-SA 2.0

Start drafting this weekend. The deadline will be here before you know it! 😄


Note: Speaking personally here (not as an OSMF Board member or as a SotM Committee member) - I really want to encourage you to submit your proposal!

Understanding OSM Issues: Existing vs. Non-Existing Problems in the Map

We know OpenStreetMap is one of the most powerful and collaborative geospatial databases in the world. It relies on contributions from everyday users, developers, humanitarian workers, and mapping enthusiasts to keep data accurate and up to date.

We know OpenStreetMap is one of the most powerful and collaborative geospatial databases in the world. It relies on contributions from everyday users, developers, humanitarian workers, and mapping enthusiasts to keep data accurate and up to date.
But like any open data project, OSM faces issues. And understanding the types of issues we encounter is essential to maintaining map quality. One simple and effective way to think about OSM data problems is, to divide them into two broad categories:

1. Existing Issues: Errors in the Map

These are problems that exist within the current OSM data. The features are already mapped, but something about them is incorrect, inconsistent, or outdated.

Common examples:
  • Incorrect tags: A residential road tagged as a motorway.
  • Geometry errors: Buildings that are misaligned, roads that don’t connect properly, or rivers overlapping with buildings.
  • Outdated features: A shop that closed years ago but still shows up on the map.
  • Inconsistencies: Using different tags for the same type of feature in nearby areas (amenity=school vs. building=school).
2. Non-Existing Issues: Missing from the Map

These are features or data that should be on the map but are completely absent. The problem here is not about fixing what’s wrong, it’s about recognizing what’s not there at all.

Common examples:
  • Unmapped buildings visible in satellite imagery.
  • New roads or paths that haven’t been digitized.
  • Missing POIs like schools, hospitals, or shops.
  • Lack of metadata such as opening hours, accessibility info, or addresses.

Why This Distinction Matters

Thinking in terms of “existing” vs. “non-existing” issues helps:

  • Prioritize tasks: Fixing vs. adding require different skills and time.
  • Guide new mappers: Beginners can focus on adding missing data, while experienced users fix complex issues.
  • Organize mapping campaigns: Humanitarian or local efforts can be tailored to the type of issue in a region.
  • Improve data validation: Tools like OSMCha, or Osmose focus on identifying existing issues, while others like MapSwipe or HOT Tasking Manager target missing data.

Please comment your thoughts and write another diary by linking this problem sets with your solutions.

In 2025, OpenStreetMap Taiwan Community has started to cooperate with Wikidata Taiwan Community to organize Street View Tour again, and in April, the tour was to Huwei and Tuku townships in Yunlin county. The funding source of this tour was Wikimedia Association of Taiwan, and the lunches for the two days (4/26 and 4/27) were sponsored by TomTom company.

The tour gathered outside the Yunlin High Speed Rail station in the morning of 4/26, and then set off to Huwei and Tuku townships to take photos of various temples related to Yunlin Liufang Mazu religion. Even though this was a street view tour, there were a lot of problems with the 360 camera this time 🫠, the one in the author’s car was always crashed (overheated?), while the one in the other car was never able to connect to the cell phone. The one on the car I was driving was always crashed (overheating?), while the one on the other car could not be connected by cell phone. Nonetheless, 53,854 street photos were uploaded to Mapillary this time (including both flat and 360 panoramic photos, some of which have not yet been uploaded at the time of writing this diary).

Supaplex introduces OpenStreetMap
Supaplex introduces OpenStreetMap

The next day (4/27) was the editing workshop for the mission, held at this year’s Red Altar (Hongtan) of Yunlin Liufang Mazu religion, where OpenStreetMap edits related to the mission were tagged with the #tt_event theme (either directly in the notes of the changeset or in the hashtags tag of the changeset), and Wikimedia Project edits were viewed in the Wikimedia project’s Dashboard. editors of Wikimedia projects can view them in their Dashboard.

About OpenStreetMap Taiwan Community

The OpenStreetMap Taiwan Community (OSMTW) comprises passionate mappers who are interested in Taiwan. Since 2010, mappers have transformed Taiwan from a coterie of individuals to a local community that gathers increasing public to participate in co-editing map projects. OSMTW is currently co-hosting monthly gatherings and aperiodic expeditions with the Wikidata local community in Taipei. Feel free to check out and join us!

Gang! Gang! Gang!

Pertanyaan mimin SGPC alias tukangsampat at the OpenStreetMap sederhana.

Banyak variasi jalan gang yang tergambar di peta OSM di Indonesia yang tidak seragam. Sebaiknya, untuk standarisasi sebaiknya, jalan gang di Indonesia:

Pertanyaan mimin SGPC alias tukangsampat at the OpenStreetMap sederhana.

Banyak variasi jalan gang yang tergambar di peta OSM di Indonesia yang tidak seragam. Sebaiknya, untuk standarisasi sebaiknya, jalan gang di Indonesia:

  • ditanda sebagai alley (highway:service, service:alley)
  • ditandai sebagai jalan setapak untuk pejalan kaki (highway:footway) - yang artinya satu jenis tag dengan jalan setapak biasa
  • atau sebagai jalan bersama (highway:living_street)

Cukup banyak gang di kota-kota maupun pedesaan di Tanah Air yang terasa terlalu lebar untuk sepeda motor namun sempit untuk kendaraan roda empat, tetapi dalam editor tag Allowed Access (motor_vehicle) bisa diartikan baik roda dua maupun roda empat, jadi sulit mencari pengecualian. Saat ini, versi mimin adalah merupakan sebuah alley.

Para que servem os dados do OpenStreetMap?

O OpenStreetMap (OSM) é um projeto colaborativo que tem como objetivo criar um mapa mundial livre e editável. Mas para além de um simples mapa, o verdadeiro poder do OSM está nos seus dados geográficos abertos, que são utilizados por milhares de pessoas, empresas e governos em todo o mundo. Mas afinal, para que servem os dados do OpenStreetMap? 1. Navegação e Mobilidade Urbana

Muitos aplicativos de GPS e navegação utilizam os dados do OSM para oferecer rotas, calcular distâncias e estimar tempos de viagem. Serviços como o OsmAnd, Maps.me e até partes do Mapbox e Uber usam esses dados. Além disso, o OSM é essencial para soluções de mobilidade urbana, como planejamento de ciclovias, linhas de ônibus e análise de acessibilidade. 2. Planejamento Urbano e Infraestrutura

Prefeituras, engenheiros e urbanistas utilizam os dados do OpenStreetMap para:

Mapear ruas, calçadas, escolas e hospitais;

Identificar áreas sem infraestrutura básica;

Planejar novos bairros e serviços públicos.

Como os dados podem ser atualizados por qualquer pessoa, isso permite uma visão mais atualizada e comunitária da cidade. 3. Resposta a Desastres e Ações Humanitárias

Durante terremotos, enchentes ou epidemias, os dados do OSM ajudam organizações como a Cruz Vermelha e o Médicos Sem Fronteiras a localizar vilarejos, rotas de acesso, centros de saúde e áreas de risco. Projetos como o HOT (Humanitarian OpenStreetMap Team) organizam mutirões de mapeamento colaborativo para ajudar regiões afetadas. 4. Educação e Pesquisa

Professores e pesquisadores utilizam o OSM para ensinar geografia, planejamento territorial, programação geoespacial e ciência de dados. Além disso, por ser livre e personalizável, permite projetos educacionais acessíveis, inclusive em escolas públicas e universidades. 5. Empreendimentos e Negócios

Empresas usam o OpenStreetMap para:

Localizar clientes ou pontos de venda;

Analisar dados demográficos e de tráfego;

Criar mapas customizados para delivery, logística ou turismo.

Por ser gratuito e sem restrições comerciais severas, é uma alternativa poderosa aos mapas proprietários. 6. Cidadania Ativa e Participação Social

Cidadãos e movimentos sociais usam o OSM para mapear problemas e soluções urbanas, como:

Buracos nas ruas;

Lâmpadas queimadas;

Áreas sem saneamento;

Roteiros acessíveis para cadeirantes.

Esse uso participativo dos dados transforma moradores em agentes ativos na construção de suas cidades. Conclusão

Os dados do OpenStreetMap são muito mais do que um mapa. Eles são uma ferramenta poderosa para construir conhecimento, promover inclusão, fortalecer a cidadania e melhorar a qualidade de vida. Seja você um técnico, estudante, gestor público ou morador comum, o OSM tem um papel para você — e cada dado mapeado pode fazer a diferença.

Прекрасно коли моя рідна громада була мною розмальована раніше. А ще приємніше коли ти малюєш сусідні громади. Сьогодні 7 травня 25 р. роботи по нанесенню на карту території Вовковинської громади завершені. Природні об’єкти громади картографовані на 100% (в т.ч. території населених пунктів, АЛЕ за винятком об’єктів всередині самих же населених пунктів, вони не враховані). Першими малювались об’єкти близ села Галузинці, останньою правкою було нанесення границь села Старий Майдан. Особлива увага була звернута на залізницю (некоректно було намальовано зупинні пункти), на траси (неточності геометрії) і на старі об’єкти які були намальовані колись іншими учасниками (актуальність була втрачена, на нових супутниках багато полів та лісів змінили свої границі).

І око милує, коли з електрички ти дивишся на не білу пусту текстуру, а на кожен нанесений об’єкт.

Wegweiser für Ansprechpartner zu Lösungen im Bereich OpenStreetMap und Geo-Open-Source-Software

Seit November 2021 stellt der FOSSGIS e.V. eine Liste von Firmen und Selbständigen zusammen, die Institutionen und Unternehmen Hilfestellung bei der Suche nach Dienstleistern zu FOSS (Free and Open Source Software) im GIS-Bereich, OpenStreetMap und offenen Geodaten geben soll. In den letzten Monaten haben wir diese Liste aktualisiert und erweitert.

Open Source funktioniert nur dann, wenn alle etwas dazu beitragen, und die “kostenlose” Software und Daten nicht nur benutzen. Viele Unternehmen auf unserer Liste entwickeln selbst bei Open-Source-Software mit, manche Mitarbeiter dieser Unternehmen sind sogar verantwortliche Maintainer von Projekten. Andere Firmen unterstützen das Ökosystem mit Sponsorings oder auf andere Weise. Das wollen wir unterstützen und besser sichtbar machen. Wir haben daher die Firmen auf der Liste gebeten, dass jeweils auf ihren eigenene Webseiten darzustellen, wo das bisher nicht eh schon der Fall war. Und in unserer Liste kann man jetzt nicht nur vermerken, welche Projekte die Firma benutzt, sondern auch ob sie selber aktiv mitentwickeln oder sogar verantwortliche Maintainer stellen.

Jeder Auftraggeber soll selber entscheiden können welcher Dienstleister der richtige ist. Wir können und wollen Ihrer Entscheidung für das eine oder andere Unternehmen nicht vorgreifen. Wir wollen mehr Transparenz in die Entscheidung bringen und es Ihnen leichter machen, die Dienstleister auszuwählen, die Ihren Kriterien genügen. Und wir hoffen natürlich, dass Sie auch explizit nach den Unternehmen schauen, die nicht nur von der Arbeit einer großen Open-Source- und Open-Data-Community profitieren, sondern die sich auch aktiv einbringen.

Für die Dienstleister heißt das: Schreiben Sie auf, was sie tun. Diese Angaben sollten so konkret wie möglich sein und aufzeigen, welche Organisationen oder Projekte (mit Link zu Projekt- und Github-Seiten) wie unterstützt werden. Ihre potentiellen Kunden wollen sich ein Bild von Ihren Aktivitäten machen. Das kann zum Beispiel auf einer speziellen “Open Source”-Seite sein oder ein Teil einer allgemeinen “Über uns”-Seite. Es ist dabei nicht so wichtig, ob sie das Ökosystem durch Spenden oder Sponsoring-Gelder unterstützen oder ihre Mitarbeiter zu Open-Source-Projekten beitragen oder diese sogar maintainen, oder ob sie auf ganz andere Weise etwas tun. Wichtig ist, dass Sie es darstellen und diese Informationen gut zu finden sind.

Die Dienstleisterliste finden Sie unter: https://dienstleister.fossgis.de/.

OpenStreetMap User's Diaries

Tumbling in the Dust!

It was a beautiful day for a hike, so I set out early at 8am sharp. I headed back to Ely, trekked some of the trails in Plymouth Great Wood, cut through the park in St Fagans, passed through Western Cemetery, then over to the iron-age hillfort in Caerau. All was going to plan — until, that is, it wasn’t. While taking some snapshots at the hillfort, I fell and sprained my ankle.

I’ve no

It was a beautiful day for a hike, so I set out early at 8am sharp. I headed back to Ely, trekked some of the trails in Plymouth Great Wood, cut through the park in St Fagans, passed through Western Cemetery, then over to the iron-age hillfort in Caerau. All was going to plan — until, that is, it wasn’t. While taking some snapshots at the hillfort, I fell and sprained my ankle.

I’ve no idea what happened – I was taking my time, walking along, and then I was flat on my face. I remember hearing a squeaking sound, the kind of sound a gym shoe makes on a squash court (so I either slipped on a root or a rock, or I killed something cute and fluffy).

So there I was , stuck in the middle of field with nothing to help me up. Great. And I somehow had to get back down a very steep hill. Brilliant. And then I had to get home. Jolly-well fantastic.

After, looking up at the sky for an hour, I managed to get to my feet. I couldn’t put weight on my over-turned ankle, so the trip back down took an age. With the aid of my trusty hiking pole, I finally got to a bus stop.

At least I got what I wanted to get — a clearer picture of the woodland trails and the layout of the roads in the cemetery (all in the name of improving Open Street Map). I also now have the perfect excuse for buying a new pair of trail boots.

Although the sprain is quite bad, nothing seems to be broken — the swelling is fairly minor, and I’m not in a great deal of pain. I won’t be strolling about for a while, but I’m hoping that the ‘while’ is a short one.


Celebrating three years of edits, and here's to many more.

Hello all, to start with, I’ve always been interested in open software and collaborative projects. I actually made an OSM account way back in 2012, as you can see on the HDYC website. I can’t really remember why I made it to be honest. I may have found it via Wikipedia or something.

But it was three years ago today that I did my first changeset. I had yet to learn about all the mapping r

Hello all, to start with, I’ve always been interested in open software and collaborative projects. I actually made an OSM account way back in 2012, as you can see on the HDYC website. I can’t really remember why I made it to be honest. I may have found it via Wikipedia or something.

But it was three years ago today that I did my first changeset. I had yet to learn about all the mapping resources available to me, especially the GSImaps/pale layer from the Japanese government. This in combination with the JOSM areaselector plugin has been really useful for quickly mapping buildings in Japan. There are a lot of hiking trails on there too, and I can see now that I didn’t really need to use my GPX track to map the trail up to the Kamiyahagi Wind Farm and the observation deck up there way back in that first edit.

I’m grateful to this community for providing me with a useful hobby to do and that I have fun with. It perfectly compliments my outdoorsy walking and hiking lifestyle, my detail-focused mindset, as well as my tendency to hyper-focus (yay ADHD!) and being comfortable with sitting on JOSM and just meditatively mapping. It’s wonderfully calming. I greatly enjoy that I’m making an impact on the world through what I love to do.

I have been making an effort to direct people to OSM resources on r/BuyFromEU as much as I can, as there’s been an increased interest in switching away from US tech companies to services like Mapy and Magic Earth and I see it as a great opportunity for more people to join and improve the map. There are so many services that use OSM, but I think a lot of users aren’t even aware that the map can be edited or that improvements are welcome. I sometimes see references to “the official OSM app,” which is referencing OSMAnd. I think for some, the concept of it just being a database that the various apps get the data from can be hard to understand. But overall, I’m really glad to see more people get on board.

I’m especially thankful to the developers of StreetComplete and Every Door for making fast, easy-to-use editors for on the go. A lot of people nowadays may not use a laptop or desktop that much, and splitting ways to add sidewalks on one side of the road or another can be a little difficult. The graphical representation of the tags in StreetComplete along with the different themes makes it really easy to focus on specific tasks. I loved seeing one Reddit user call it “The new PokémonGo!

In Every Door, it’s so easy to just plop down a POI like a drinking_water or restaurant on the go, rather than trying to remember to do it later via a picture. Especially if I have time to kill while waiting for my order ^_^. Having the Name Suggestion Index pre-loaded means that the correct vending machine brand shows up and makes the tags nice and pretty.

While I’ve been focused on my local area mostly, I have done a little contribution to HOT projects and MapSwipe. It’s great to have a local impact through more accurate and additional hiking trails, drinking water locations, and toilets, but having a more global impact through armchair mapping is wonderful. I get to help people and make sure that aid is delivered to everyone by literally putting them on the map.

Lastly, I love watching all the conference talks to see how different individuals or organizations are using or contributing to the map. It’s fascinating and inspires me to improve the map even more.

Anyway, that’s enough rambling from me. Love this community and I’m so excited to be a part of it.

[1] retrospect of the EU-funded OSM project EuYoutH | Map © OpenStreetMap contributors.

About us

  • Raquel Dezidério Souto’s statistical analysis of weeklyOSM’s profile over the past ten years will be submitted to the State of the Map 2025, which will be held in Manila, Philippines, from 3 to 5 October. Tabular and graphical results are already available and have been updated recently.

Mapping campaigns

  • The Colombian National Mapathon 2025 for risk management kicks off on Monday 5 May. It is organised by the National Unit for Disaster Risk Management with support from HOTOSM and other organisations. From 5 May to 27 June, participants can choose from several sessions. If you complete 5 hours of mapping and participate in at least two sessions, you can request an official certificate of participation. Register here .

Community

  • Juminet has analysed the completeness of address data in Belgium and found that OpenStreetMap contains 3.9 million addresses, covering 87.6% of the 4.45 million listed in official records.
  • Kumakyoo concluded his series on his new OMA file format with a larger example, a map from a micromapping project. He also summarised the feedback he has received and gives an outlook on what will happen in the coming months.
  • Rphyrin recounted his experience at the OpenStreetMap Indonesia Community Mapping Party 2025, which took place at Plaza Indonesia on Saturday 26 April.

OpenStreetMap Foundation

  • Minh Nguyễn, newly appointed as OpenStreetMap Foundation’s Core Software Development Facilitator, outlined his background, shared key initiatives, and highlighted opportunities for collaboration.

Local chapter news

  • In a recent instalment of its blog series spotlighting OpenStreetMap contributors and mapping communities, OpenStreetMap US sat down with Jacob Hall and Daniel Schep, of MapRVA, Richmond, Virginia’s local mapping group. The interview delved into the group’s origins, their regular activities, and recent community-led initiatives, including their efforts during the January 2025 Richmond ‘Water Crisis’ to map the disaster’s impact.
  • Following a recent discussion on the two address schemas used in France, one with the associatedStreet relation and one without, contributors to OpenStreetMap France have been invited to take part in a survey on whether the community should adopt a single, unified address schema. Voting remains open until Sunday 11 May.

Events

  • The organisers of SotM LatAm 2025 have announced the extension of the deadline for submitting talks and workshops, which can be done until Friday 9 May.
  • Héctor Ochoa Ortiz reported that the ‘OpenStreetMap: Mapping and Hiking’ event took place on Thursday 10 April, at the University of Camerino, Italy. Participants were split into small groups for a three-hour hike in the villages and hamlets around Camerino, with each team collecting geographic data using apps including Every Door and uploading photos to Panoramax. In the afternoon, participants mapped missing buildings and roads from desktop computers. Saverio Delpriori, a technician from the regional government of Marche, also attended the event and presented the region’s geographic information and tourism infrastructure, highlighting plans to integrate OpenStreetMap data in the future.
  • The third edition of the Participatory Mapping and Social Cartography Workshop aims to bring together researchers from Portuguese-speaking countries (Angola, Brazil, Cape Verde, Guinea-Bissau, Equatorial Guinea, Mozambique, Portugal, São Tomé and Príncipe, and Timor-Leste) who have in common the use of participatory or collaborative mapping methodologies. The event will be held online and in Portuguese. As a preparatory stage for the event, a ‘showcase of mapping projects’ is being organised for presentation of individual projects. To take part, simply fill out the registration form by Tuesday 20 May, giving your basic details. The team will then contact you to inform you about its acceptance and align the details. Thanks to the sponsorships of the Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro (research funding agency) and the company IVIDES DATA.
  • The State of the Map Europe 2025 will take place on 14 and 15 November at Abertay University in Dundee, UK. Interested attendees are encouraged to subscribe to the newsletter via the official website to receive updates on ticket availability.

Education

  • Séverin Ménard will present an online workshop on post-disaster mapping on Monday 19 May, from 15:00 to 17:00 UTC. This session will be in Portuguese, completing the series of workshops that were previously given in English and French (we reported earlier). Please register for the event by Sunday 18 May in order to receive the alert. The session will cover the post-disaster mapping of the state of buildings and roofing material. The area of interest is Mayotte, where projects have been created on the HOT Tasking Manager, by OSM France.

OSM research

  • Fatemeh Rafiei explored in her recent master’s thesis at HeiGIT how machine learning techniques can be used to predict demographic characteristics at the building level. The study integrated a variety of open urban datasets and demonstrated how spatial indicators derived from openrouteservice can enhance predictive modelling.

OSM in action

  • Matt Round has just launched Comic Sans Maps. True to its name, all the map labels are rendered in Comic Sans.
  • Responding to a request from the OpenStreetMap Indonesia community on Telegram, altilunium has developed BRT-tj, an interactive map that visualises Transjakarta bus routes and stops using OpenStreetMap. The application processes data directly from Transjakarta’s official General Transit Feed Specification file, which is publicly available on the agency’s website.

Software

  • Andrii Holovin raised the issue what the new OSMCha palette has for people with certain types of colour perception impairment. Jake Low experimented with different approaches and invites everyone to join the discussion of the issue on GitHub.
  • HeiGIT reported that they will be launching their Climate Action Navigator on Thursday 15 May. This dashboard will offer high-resolution, open data-based insights into key climate action indicators, such as CO2 emissions from residential heating or urban active mobility infrastructure. There will be an online launch event on Thursday 5 June at 14:00 (CEST) for you to get valuable insights on the development and use of the navigator.
  • Oliver Wipfli reported that MapLibre GL JS now supports rendering South and South-East Asian scripts through the maplibre-gl-complex-text plugin, which is powered by the HarfBuzz text shaping engine. Supported languages include Bengali, Gujarati, Gurmukhi, Kannada, Khmer, Malayalam, Burmese, Oriya, Tamil and Telugu as well Devanagari script.

Programming

  • Inspired by a FOSSGIS 2025 talk by Michael Reichert on how and where to best complete OpenStreetMap, Daniel showed how we can use a routing engine to find and prioritise ways with missing tags which are most important for (bike) routing.
  • Martin Fleischmann presented the inner workings of NeatNet, which he has developed and documented with Anastassia Vybornova and James D. Gaboardi. NeatNet is a toolbox designed to simplify the geometry of street networks by producing representations that more accurately reflect the morphological structure of urban space.
  • Following last week’s in-depth exploration of space-filling curves and the BIGMIN optimisation (we reported earlier), Daniel has released a new package called zbush, which applies these techniques to spatial indexing. The release has sparked a lively discussion on Mastodon.

Releases

  • The latest version of Mapnik, released on Thursday 24 April, is v4.0.7, which has added support for libc++ equal to or higher than version 19.

Did you know that …

  • … you can now add location information to your OpenStreetMap profile page? This feature was implemented by David Tsiklauri, based on a pull request submitted on 5 November 2024, and was merged into the openstreetmap-website code base on Friday 25 April.
  • places.pub is a service that makes OpenStreetMap geographical data available as ActivityPub objects? This could extend the functionality of the ActivityPub protocol by describing geosocial activities and adding the location of an actor, content, or activity.
  • Arnis can create Minecraft Java Edition worlds that reflect real-world geography and architecture using OpenStreetMap?

OSM in the media

  • [1] On the occasion of the tenth anniversary of weeklyOSM, the Erasmus+ programme of the German Conference of Ministers of Education and Cultural Affairs reported on several OpenStreetMap-related projects that the EU has funded in the past. These include joint mapping activities for teachers and students for the OSM community, humanitarian mapping initiatives, and partnerships with UN Mappers to map areas for peacekeeping operations.
  • Argentina’s Postal Service has faced sharp criticism after an interactive map on its website referred to some disputed South Atlantic islands as the ‘Falklands’ rather than ‘Malvinas’, and listed their capital as ‘Stanley’ instead of ‘Puerto Argentino’. The state-run agency attributed the mistake to an ‘involuntary error’ caused by their map provider, OpenStreetMap, accessed through Leaflet. Amid the mounting backlash on social media and political protests, the map was taken down. In a subsequent statement, the Argentine Post reaffirmed its support for Argentina’s sovereignty claims over the archipelago.

Other “geo” things

  • On Tuesday 29 April the European Space Agency successfully launched its ‘Biomass‘ satellite. This satellite, which was sent into orbit from the Guiana Space Centre aboard the European-made Vega C rocket, will spend the next few years measuring the global biomass of forests, a task that has previously only been based on estimates. Biomass goes beyond surface imaging by sending radar waves through tree canopies to the forest floor, capturing tree trunks and branches. The satellite aims to create detailed three-dimensional models of forests to enhance our understanding of their role in the global carbon cycle.
  • Werner Pluta, of Heise, provided a concise overview of the history of GPS, beginning with US President Bill Clinton’s landmark decision to remove Selective Availability in May 2000, its transformative impact on global navigation, and how this move spurred the development of alternative satellite navigation systems by other nations worldwide.
