Mapping

• historic=ceremonial_gate, a tag proposed to represent traditional symbolic gates in East Asian cultural regions (such as Chinese Paifang/Pailou, Japanese Torii, Korean Hongsalmun/Iljumun, and Vietnamese Tam Quan), is currently under discussion.

Mapping campaigns

• Mapillary and HERE announced CompleteTheMap Europe, a collaborative effort to enhance street-level imagery coverage across major European cities. Registration must be completed by Thursday 12 June.
• The OpenStreetMap Russia community has announced ► an upcoming online mapping initiative aimed at enhancing the digital map of the city of Morshansk. The mapathon has been running since Saturday 31 May and will run until Friday 13 June. Participants will use up-to-date resources including 2024 Yandex street-level panoramas and Esri satellite imagery to contribute detailed mapping data to one of the few remaining under-mapped cities in the country.

Community

• Jim Spath shared some progress on improving the display of EV charging stations in Android Auto OsmAnd.
• Kumakyoo advocated for mapping pavements as separate geometries, rather than using the sidewalk=* tag on roads, arguing that in certain cases, this tag alone makes it impossible to accurately determine the layout of pedestrian crossings from OSM data.
• Malle_Yeno blogged his thoughts on wheelchair accessibility mapping: do establishments need powered doors to be accessible? Do we evaluate accessibility at the POI feature level, or in context?
• Andy Townsend thought about using the diameter_crown tag to render trees according to their size.

OpenStreetMap Foundation

• The OpenStreetMap Operations Team has successfully mitigated a large-scale web scraping attack targeting the OpenStreetMap Wiki. The botnet, which operated through over 2 million unique IP addresses, and is still growing, was aggressively scraping content via proxies. In response, the team implemented a defensive measure by blocking more than 32,000 IPv4 /24 ranges. Members of the community have proposed deploying Anubis, a proof-of-work challenge system, to further protect the wiki from automated scraping. However, discussions are ongoing regarding potential licensing concerns associated with its implementation.

Events

• Katja Haferkorn announced ► the planned formation of the new Programme Committee for FOSSGIS 2026. Anyone interested in joining the Programme Committee is invited to send an email to FOSSGIS by Tuesday 15 July.
• FOSSGIS held ► its first Networking Meeting for Geoinformatics Professionals, FOSSGIS Conference Participants, Members, and Interested Members of the FOSSGIS Community on Wednesday 4 June. The next meeting is scheduled for Wednesday 10 September, again at 6:00 PM (UTC+2).

Education

• Hermann106 shared ► several useful links for learning how to use JOSM.

Maps

• ^[1] Christoph Hormann developed some design concepts for more differentiated depiction of coastal infrastructure based on OpenStreetMap data.
• Tkhir noticed ► that some of Kyiv’s streets are named after fruits and vegetables. Andrii Holovin added emojis in a comment to provide context about the etymology of the names.
• Christoph Hormann has developed a map design capable of rendering aquaculture installations (landuse=aquaculture).

OSM in action

• Costa Line has developed ► an interactive OpenStreetMap-based web map that can be used to track the movements of all the ships in its fleet.
• The Department of Posts under India’s Ministry of Communications has launched the Digital Postal Index Number (DIGIPIN), a grid-based digital address system aimed at modernising postal services and improving address accuracy across the country. The official portal, Know Your DIGIPIN, utilises an OpenStreetMap base map to allow users to conveniently look up their DIGIPIN based on their geographic location.
• Student Justin Fung built an interactive map to help wildfire evacuees. Justin presented his map on CBC News.

Open Data

• In Ukraine, over 1.5 million addresses have already been verified ► in the Unified State Register of Addresses, as the second stage of the project gains speed. The register is being developed with government support and help from UK Dev, the Eurasia Foundation, and the East Europe Foundation. Verified address data will improve map accuracy, reduce errors, and support better public services.

Software

• Project OSRM is developing a new area routing feature that will enable the calculation of optimal routes across walkable open spaces.
• tvbrene has built ‘ExtendedClipboard’, a JOSM plugin that provides up to 10 independent clipboards for storing OSM objects for later selection.
• Tykayn has developed the Mon Commerce OpenStreetMap (My OpenStreetMap Business), a tool that invites POI owners in France, to maintain their OpenStreetMap data. It allows a place to be edited without requiring a personal account (the edits are proxied through the osm-commerce-fr OSM account).

Programming

• Archit Rathod blogged about his upcoming Google Summer of Code 2025 contribution, where he will build a system for incorporating real-time road closure data with OpenStreetMap.
• Ayush Dhar Dubey outlined his plan to modernise the 3D Model Repository as part of the Google Summer of Code 2025.
• Anders Borg has created a Python application that converts Overture map data (based on OSM and other open data) to a cohesive STL model, which can then be modified for 3D printing of a certain map area.
• Victor introduced OsmAnd’s new Highway Hierarchy Routing, a routing engine that segments maps into small clusters with defined border points, enabling pre-calculated shortcuts for faster routing within and between neighbouring clusters.

Releases

• Florian Bischof announced the release of Leaflet 2.0 Alpha. This version marks a major modernisation of the Leaflet codebase, including the removal of Internet Explorer support, legacy methods, and polyfills. It also adopts modern standards including Pointer Events and is now published as an ESM module.
• Organic Maps is ‘back on track’, as they say, after their recent management problems. The May version is now available. This update includes various improvements to the map, including the removal of the referral link to Kayak and minor fixes for Android. Users are also invited to take part in beta testing for the June version, which promises a range of new features.
• CoMaps, a fork of OrganicMaps (we reported earlier), has released a preview version. For now, it is distributed as a downloadable APK file, with plans to release it on F-Droid, Google Play, the App Store, and Accrescent.
• Alexis Lecanu released version 1.12.0 of Baba, a mobile app for contributing to the Panoramax project. This release includes several bug fixes and a newly added street view.
• Volker Krause shared a round-up of the developments over the past two months in KDE Itinerary. Key updates have included enhanced editing capabilities for train and bus trips, the introduction of a new departures view, integration with OpenRailwayMap, and the addition of several new features in the Transitous backend.

Other “geo” things

• Engaging Data has developed ‘Snake on a Globe’, a geography-based twist on the classic snake game. Players navigate the globe to reach apples placed in world cities, testing both strategy and geographic knowledge.

OVERVIEW

I stumbled across a website which hosts every single Soviet military map 1:200k from 1985.

I plan to analyze each quadrant starting from the top left corner to the western side of russia, and map any unmapped settlements, buildings or other features.

I will update the post as time goes on, this is a VERY-long-term project.

Added all the peaks, ridges, survey points which were on land in quadrants R60-05 and R60-011. Added capes, fixed lake names and added missing homes (how anyone can live there is beyond me). Tommorrow I will focus on adding rivers, the survey points along the rivers, adding the singular road and the rest of the capes

As OpenStreetMap becomes a central part of global mapping infrastructure, it’s worth asking:

Are corporations offering as much or more as they are getting from their OSM involvement?

Some corporations benefit enormously from OSM using it to build commercial services, run logistics, and analyze market data. But these same companies often have access to large, rich datasets, especially from telemetry and user behavior, that are far beyond what the average contributor can collect.

If shared, such data could dramatically improve OSM’s accuracy, completeness, and utility. But how much of this data is actually being shared?

There’s a tension here between open knowledge and proprietary advantage. While some companies do contribute back through edits, funding, or tools, the scale of these contributions doesn’t always match the value extracted.

This leads to deeper questions: - Is the current model of corporate engagement with OSM sustainable? - Are the benefits of the open model being eroded when sharing isn’t reciprocal? - Could new norms or frameworks encourage deeper, more equitable collaboration?

The OSM community thrives on openness, transparency, and volunteerism. As more private actors join, the long-term health of the ecosystem may depend on whether those values are upheld not just by individuals, but by corporations as well.

We are excited to announce the call for nominees for the OpenStreetMap Awards 2025! The awards ceremony will take place this October at the State of the Map 2025 conference in Manila!

These community awards are nominated and chosen by the community.

The State of the Map Working Group

The State of the Map conference is the annual, international conference of OpenStreetMap, organised by the OpenStreetMap Foundation. The OpenStreetMap Foundation is a not-for-profit organisation, formed to support the OpenStreetMap Project. It is dedicated to encouraging the growth, development and distribution of free geospatial data for anyone to use and share. The OpenStreetMap Foundation owns and maintains the infrastructure of the OpenStreetMap project, is financially supported by membership fees and donations, and organises the annual, international State of the Map conference. Our volunteer Working Groups and small core staff work to support the OpenStreetMap project. Join the OpenStreetMap Foundation for just £15 a year or for free if you are an active OpenStreetMap contributor.

OpenStreetMap was founded in 2004 and is an international project to create a free map of the world. To do so, we, thousands of volunteers, collect data about roads, railways, rivers, forests, buildings and a lot more worldwide. Our map data can be downloaded for free by everyone and used for any purpose – including commercial usage. It is possible to produce your own maps which highlight certain features, to calculate routes etc. OpenStreetMap is increasingly used when one needs maps which can be very quickly, or easily, updated.

My parents had rented a barge to explore the Barrow Navigation in Ireland for a week. I joined them on three days to capture water-level imagery with my GoPro (and to catch up with them as well). There are unfortunately 1.7km missing where the battery of the camera ran out, and there was no place to moore to exchange or charge it.

All the images are uploaded to Mapillary (Sequence key for 1st sequence: l2Yx6tGPdI9qRUAwZLvTFe) and Panoramax (Sequence key for 1st sequence: 7fe2a04f-e18c-4cf3-8bb5-48af1d1cf7ad); there were 2,446 in total, if I remember correctly. This being Ireland, of course it rained for some bits of it, so the images between Carlow and Athy are a bit blurry.

Along the way, I tried to improve the waterway mapping, especially mooring places and water supply. Mooring places don’t seem to get rendered at all (not even in the waterways map on OSMAnd), so that was a bit of a waste of time from my perspective. I’m hoping that there is an app out there that does render them.

One lock South of Goresbridge is no longer in use which means that they had to turn around in Goresbridge, even though the Barrow Navigation continues for 12 more locks or so. It’s probably fine in a kayak that you can lift out and carry around the broken/ silted up lock. Another lock was broken as well, but the lock keeper was able to fix it for them within an hour.

I also tried to map the actual route that boats are allowed to take, because when you have several arches in a bridge, there is usually only one dedicated arch the boat is supposed to take, but I have not found a documented way of mapping that. So I used a line in a route relation, but there aren’t even waterway routes as far as I could find. Water supply was also someone important, not just for drinking water supply, but because they needed to refill their tank for washing the dishes and taking showers. Half of the water taps didn’t seem to work, and some were only for drinking water, and you couldn’t connect your boat’s hose to it. I haven’t found out whether there is a way to map the hose connecting option. Come to think of it, when they had to carry 5l bottles in between the tap and the boat, because there was no hose connector, it would have been nice to be able to either hang the bottle/ bucket like you could on the old village pumps or have a little plinth underneath. But that’s not really a mapping issue, that’s a badly executed amenities issue.

I had mapped the Barrow Navigation from satellite imagery, created Wikidata (Barrow Navigation Q134700972) entries for all the locks etc last year in preparation of their visit, so uploading photographs (Barrow Navigation on Wikimedia) of all the locks and most of the bridges was convenient enough. I had even made a video on how to map mooring points at the time: on Youtube.

This all sounds a bit negative, but it was actually fun to see the Navigation from that perspective. I had walked parts of the Barrow Way trail which runs parallel two years previous (I think), so some of the amenities etc along the bank were fairly well mapped.

Discoveries along the way

I spotted two more milestones in addition to the ones I had spotted walking the Barrow Way, both along where I had already walked.

I also found out about a newish European Hiking trail called The Columban Way (Via Columbani) which connects Ireland with Italy (with a few countries in between). I’ve created a hiking relation; it would be marvelous, if other people could add to it.

Not mapable discoveries include a great number of swans (incl. 5 cygnets), an otter, a heron eating an eel, a kingfisher and lots and lots of plastic bottles swimming in the canal.

(The images are all on Wikimedia.)

2025年5月24日（土）神奈川県横浜市の上大岡でOpenStreetMapマッピングパーティーを開催しました。上大岡駅東口から南東方面、谷戸地形の調査散策。 Field Papersとmuramotoさん作成の地形3Dプリントを参考にしながら、崖に張り付いた谷戸的住宅街などを確認しました。高い場所へ移動して谷戸の全景をチェック、「黒船来航」で人が集まったとされる丘に移動し、横浜港方面を眺めました。その後、富士見ポイントなどに寄りつつ散策、上大岡駅に戻りました。

Když se v pozdním jaru nebo na začátku léta procházíte po loukách v okolí Lipna, Frymburka nebo Českého Krumlova, občas si všimnete neznatelných změn v porostu, rovných linií, kde vegetace roste s jinou intenzitou. Nejde si nevšimnout ani častých betonových skruží uprostřed polí, nebo pastvin.

Jsou to stopy minulosti, kdy se ve velkém prováděly meliorace s cílem odvodnit zamokřené louky a přeměnit je v intenzivně využívanou zemědělskou půdu. Dnes tyto bývalé, ale stále funkční zásahy do hydrologického režimu krajiny znovu otevírají diskuse. Nejen mezi vědci a ochranáři, ale i mezi zemědělci a krajinnými inženýry.

Dědictví meliorací

• Na obrázku je výřez louky s patrnými liniemi melioračních brázd u osady Skláře, nedaleko Hořic na Šumavě. Středem louky prochází hlavní odvodňovací kanál, který je osazen skružemi. Ty slouží především jako přístup k čištění. Někdy je z kanálů vyvedena voda na povrch za účelem napáječky dobytka

Meliorace se budovaly ve velkém v 60. až 80. letech 20. století, a to včetně podhůří Šumavy. Podzemní potrubní systémy, i povrchové odvodňovací příkopy, regulační stavby – to vše mělo pomoci k lepším pěstebním podmínkám a možnosti vjet na pole těžkou mechanizací. Jenže s nástupem klimatických změn a častějších epizod sucha začíná být jasné, že meliorace zanechaly v krajině dědictví, které je v nových podmínkách kontraproduktivní. Louky, které by měly přirozeně zadržovat vodu, ji naopak rychle odvádějí pryč.

Zadržet vodu, kde to jde

V posledních letech se karta obrací. V rámci projektů podporovaných nejen z národních, ale i evropských fondů, vznikají na někdejších odvodněných lokalitách nové tůňky, mokřady, revitalizují se staré příkopy. V praxi to znamená i technicky náročnou a ne vždy úspěšnou likvidaci starých drenážních trub a zásypy potrubních jam, či obnovu pramenišť, které byly melioracemi zaslepeny. Vše za účelem zlepšení schopnosti krajiny zadržet vodu a podpořit biologickou rozmanitost.

Například na louce nedaleko Veleslavic, byla v minulém roce vybudována soustava mělkých tůněk. Kromě nich i zasazeny nové stromky na březích a doplněno pár odpočinkových míst pro výletníky. Nové tůňky nemají žádný stálý přítok, voda se sem dostává přirozeně ze svahu když zaprší a nebo je v kopcích vlhko. Kolem tůní už začíná růst rákosí a vodní rostliny, bude ještě pár let trvat, než se to celé usadí. Toto zavodnění louky má význam pro místní mikroklima a biologickou rozmanitost jak rostlin, tak živočichů. Skutečný efekt tůňkami vylepšené louky poznáme až v budoucích letech.

Louky jako kulturní fenomén

Louky v oblasti Šumavy a jižních Čech nenesou pouze produkční hodnotu. Jsou příkladem kulturní krajiny, která vznikla díky staletému soužití člověka s přírodou. Jejich pravidelné sečení a pastva krav, ovcí či koní zajišťuje otevřený charakter krajiny a brání samovolné sukcesi dřevin. Navíc jsou domovem řady ohrožených druhů rostlin a živočichů, které jsou vázané na vlhké nebo extenzivně obhospodařované travnaté biotopy. Proto jsou tyto typy luk zařazovány do agroenvironmentálních programů, které poskytují finanční podporu za jejich šetrné obhospodařování.

Popis v OpenStreetMap

Pro přírodovědce, mapovače krajiny i nadšence otevřených dat má OpenStreetMap možnost, jak tato historická i nově vznikající opatření zaznamenat. Mapování starých odvodňovacích příkopů, melioračních sítí, ale i nových tůněk je možné provádět pomocí tagů jako drenáže man_made=drain, jezírka water=pond, louky landuse=meadow, mokřady natural=wetland nebo pastviny pasture=*. Podklady lze čerpat z aktuální ortofotomapy, historických map (např. 3. vojenské mapování), ale nenahraditelná je i osobní ználost terénu a rozhovory s místními hospodáři.

Co s tím?

Kdybyste zavedli řeč s místními lidmi, jejichž rodině ty louky patřily před kolektivizací a později po privatizaci, vyjádření nebude úplně jednoznačné. Mají historickou zkušenost, že mokrá louka nebyla průchozí pro žádnou zemědělskou techniku, takže zbývalo než pást krávy, nebo odvodnit. Tenkrát, v době budování nových zítřků sjedocená a vysušená pole a louky mohly nést vyšší úrodu.

Dnes, z různých příčin, ať už je to výnosnost na hektar a tržní cena hospodářských plodin, je tady zemědělská výroba ekonomicky nemožná, takže východiskem je skutečně jen udržování luk sečením s finanční podporou od státu, nebo pastvou menších stád krav.

Z pohledu vědy i správy krajiny je důležité mít přehled o rozmístění melioračních systémů a současně sledovat, kde dochází k funkčním revitalizacím. Není vždy jednoduché najít v archivech zákresy melioračních prací, často vůbec neexistují. Mapování podle leteckých snímků v tom může hrát doplňkovou roli jako nástroj komunitní participace a sdílení informací o krajině napříč obory.

V době, kdy krajina čelí klimatickým výzvám, tu hraje roli i tzv “overview efekt” kdy se pozorovateli propojí více různých postřehů na totéž do jednoho celku. Jsou potřeba otevřená data, otevřené oči a ochota dívat se na krajinu jinak, než jen prizmatem okamžitého výnosu.

Vernetzungstreffen für Geoinformatiker:innen, FOSSGIS-Konferenz-Teilnehmende, Mitglieder und Interessierte in der FOSSGIS-Community

Es begann mit einem Anruf einer Onlineteilnehmerin der FOSSGIS 2025, die ihre Begeisterung zur Konferenz zum Ausdruck brachte und nach Vernetzungsmöglichkeiten fragte. Die Idee ein Vernetzungstreffen online zu veranstalten, in dem sich die Teilnehmenden kennenlernen und austauschen, war im Raum.

Für den 04. Juni geplant, startete die Veranstaltung um 18 Uhr. Sieben Teilnehmende waren dabei, lernten sich kennen, erzählten woher sie kommen, womit die sie sich hinsichtlich FOSSGIS, Geoinformatik beschäftigen und suchten und fanden Kontaktpunkte. Oft ist es so, dass Geoinformatiker:innen in ihrer Institution die einzigen oder in einem sehr kleinen Team sind und deshalb den Austausch über die eigene Institution hinaus brauchen. Veranstaltungs- und Aktivitätenhinweise wurden dankbar angenommen.

Katja stellte den Verein und aktuelle Aktivitäten vor und stand für Fragen zur Verfügung.

Alle waren sich einig, dass diese Art Treffen sehr sinnvoll sind und fortgeführt werden sollten, um Interessierte Leute onzuboarden und Vernetzung zu ermöglichen. Auch Themen in Kleingruppen besprechen, wurde als gute Idee bestätigt.

Als Folgetermin ist der 10.09.025, wieder um 18 Uhr vereinbart.

Hallo Community,

Ich habe momentan folgendes Problem. Durch unseren Ort ist ein Mapper gegangen und hat 40 von ca. 250 Hydranten gemappt. Diese sind zum Teil fehlerhaft (Falscher Standort, Falsche Typ, kein Hydrant nur Entlüftung, Löschbrunnen als Hydrant deklariert, usw…) von den 40 Stück sind es ca. 10 Stück. Die ganzen Überfluhrhydranten ca. 20 Stück ohne Rohrdurchmesser angegeben. Somit für die Feuerwehr nur bedingt brauchbar. Da der Führungskraft wieder nachsehen muss welche Leitung es ist, um das bereite gestellte Löschwasser zu berechnen.

Ich wollte darauf hin die 40 Hydranten löschen, dies wurde mir leider untersagt. Stattdessen soll ich diese alle Richtig stellen. Dies sehe ich aber nicht als meine Job. Ich kann dies gerne an die Gemeinde weitergeben, diese wollen aber dann einen Lohn für die Arbeiten. Wer übernimmt die Kosten dafür?

Was hilft es uns, wenn nur 40 von ca. 250 Hydranten in dem System sind, wir aber seit 10 Jahren ein anderes System verwenden hier jeden Hydranten mit Bild, GPS Daten, Kennzeichnung ob Einsatzbereit, usw. hinterlegt haben. Diese Jährlich überprüfen und an den Wasserzweckverand Rückmelden mit Schäden.

Die Nachbarwehren nutzen Openfiremap, diese wird mit den OSM Daten gespeist. Sollte nun eine Nachbarwehr zu uns zum Einsatz kommen und sieht in Ihrem System, das ein Hydrant in der Nähe ist, dies aber nicht stimmt?? Weil es nur eine Entlüftung ist oder ein Löschbrunnen.

Wir sind der Meinung das solche Daten von Leuten gemappt werden sollen, die eine Ahnung haben, was Sie machen. Somit die ~Zuständige~ Gemeinde / Stadt / Feuerwehr.

Was ist eure Meinung dazu??

At work¹, I started creating a real pedestrian routing that uses sidewalks rather than the middle of the road (unlike most pedestrian routing software nowadays). This is necessary for calculating safe routes to and from schools. In this case, it really matters which side of the road the children use and which crossing they take.

The OSM community mainly uses two methods of mapping sidewalks (and the choice between these two methods directly influences the mapping of crossings): One option is to attach them as tags to the road (for example sidewalk=both), and the other is to use separate geometry. In this post, I would like to show an example where mapping the geometry separately makes a huge difference.

A Dangerous Crossing

The image shows one of Germany’s most dangerous places for pedestrians, according to accident statistics ². This crossing is located near Rothe Erde in Aachen.

The following figure, taken from a screenshot of JOSM, shows the OSM data for this crossing.³

As you can see, the crossing has five arms, one of which (the south east arm) is split into two separate lanes. There is a pedestrian crossing with traffic lights at each arm and tags reveal that there are sidewalks on both sides of each arm.

The Question

Let’s take a closer look at the two crossings at the north and north-west. Can you guess the geometry of these two crossings? Are they parallel to the next street (A in the figure above) or perpendicular to the street they cross (B in the figure above)? What do you think? Please try to answer this question, before reading on…

The Answer

Looking at the aereal image reveals, that neither is correct: One crossing is parallel to the next street (with the node of the crossing being placed slightly off) and the other one is (almost) perpendicular to the street it crosses:

What I want to demonstrate with this example: It’s impossible to determine the geometry of the pedestrian crossings from OSM data with attached sidewalks. You need separately mapped sidewalks to be able to determine this geometry.

Why Does it Matter?

Take a look at the next figure: Cars travelling from south east to north and pedestrians crossing the arm going north get a green light at the same time. This is called “bedingt verträglich” in German, meaning “limited compatible”, and is a standard for traffic lights in Germany.

The cars turn at an angle of 135°. This is considered dangerous because cars can travel much faster than they could at, say, 90°. This angle can be derived from OSM data. However, the position and direction of pedestrians cannot be derived: A pedestrian at position A might not see an approaching car because it is coming from behind him, while a pedestrian placed at position B will have a better chance of spotting the car in time because, in this case, the car is arriving from the left.

There is one more important detail: The distance from one side of the street to the other side of the street differs in both cases: In case A, it is 16.7 meters; in case B, it is only 13.9 meters. A difference of 2.8 meters, or about three seconds less of exposure, could make the difference between a safe and unsafe crossing. Again, this can be known with separately mapped sidewalks (if kerbs are mapped), but is almost impossible to determine otherwise.

This was just one brief example of an application of OSM data where the geometry of pedestrian ways is important and where this information cannot be obtained if sidewalks are mapped as part of the highway. There are more, and perhaps I will write about them in an upcoming blog post.

1. Research project SAFER: The project aims to create a smart pedestrian router to help plan better school routes. In addition to distance, other criteria like safety (which cannot be measured by numbers) will be taken into account. ↩

2. In a 2023 study, I analysed all cluster points of pedestrian accidents in Germany between 2019 and 2022. With 8 accidents, two of which resulted in severe injuries, this crossing was ranked 10th. ↩

3. I removed some unrelated details. ↩

10 years + a few days ago, we held the White House Mapathon.

https://obamawhitehouse.archives.gov/blog/2015/05/28/citizen-cartographers-unite-report-first-white-house-mapathon

Over a hundred mappers gathered and livestreamed the happenings, shared stories of cool mapping projects, dialed in Peace Corps volunteers from the across the globe, and naturally mapped. There were cake pops decorated like globes. Along the walls, stunning reproductions of historic American maps provided by the Archives (I snagged a couple prints, they hang in my office to this day). Everyone dressed formal for the setting, except Alex Barth in usual attire, commenting “Wow OpenStreetMap is fancy today”.

Can you imagine that occurring today? Unimaginable. Of course not.

These kinds of convenings are by their nature fleeting. A recognition and shared touchstone for future work. Yes a bit hype-y, but grounded in real work and real opportunity. This was the era of upswing in open government, open data, the early days of 18F and USDS. The community that gathered there continued championing open mapping in the years after. Some of the most enduring are YouthMappers https://www.youthmappers.org/ and OSM US government initiatives https://openstreetmap.us/our-work/trails/.

We’re now in the age of BS. Truth or not does not matter. That comes from government and AI vibes.

OpenStreetMap is anti-bullshit https://www.linkedin.com/posts/mikelmaron_i-just-joined-the-humanitarian-openstreetmap-activity-7270058802240978945-89Oj/. OSM is for Truth. We map what’s on the ground, right before our eyes. Humans are at the center of the process. The infrastructure connects local information to a global ecosystem nearly effortlessly. And the projects are resilient, beyond any individual organization’s control. In my mind, my brief time in government was focused on dissolving barriers, between government and the communities it serves, and within government as well. Intentionally, this connection to open community means endurance beyond any entity’s interests, allowing for ebb and flow of collaboration. This month, OpenStreetMap will be contributing to the proceedings at the United Nations Open Source Week https://www.un.org/digital-emerging-technologies/content/open-source-week-2025

Anyway, it was super fun and I learned a lot about pulling off events like this. I proposed something that seemed so implausible, but was taken seriously by my wonderful collaborators Cori Zarek Denise Brown Benson Wilder Megan Smith.

Now we need to be more creative than effort, dissolve more barriers than ever, do things quickly and adaptably, and definitely have fun.

Como é habitual para mim, encontrei-me perdido em indecisões sobre como começar coisas.

Desta vez foi na sequência de uma conversa de pequeno-almoço em que estive a falar de projetos interessantes que rodem o OpenStreetMap, onde constatei que tenho que arranjar um sitio onde reunir links para mais tarde os encontrar sem ter que andar a fazer scroll em conversas de Telegram, Discord ou Mastodon.

E depois de considerar as muitas opções disponíveis sem encontrar uma ideal, decidi que o melhor é deixar de fazer planos e fazer-me à estrada.

Coisas interessantes que descobri hoje:

• Open Architect Map - Interactive map showing the architects who created buildings and structures, based on OpenStreetMap and Wikidata.
• Open Etymology Map - Interactive map that shows the etymology of names of streets and points of interest based on OpenStreetMap and Wikidata.

En el primer trimestre de 2025 me he dedicado a mejorar el mapeo en la Amazonía colombiana, enfocando resguardos indígenas, caseríos y asentamientos, ríos y, con mayor preocupación, selva deforestada.

Did you know that …

• … there’s an OpenStreetMap Bluesky feed? It allows you to see posts featuring the hashtags #osm and #openstreetmap.
• … you can open a random OpenStreetMap note from any country of your choice?
• … the OpenStreetMap API has a rate-limiting feature that prevents new users from committing large, potentially damaging changesets? After it was implemented in the backend, some user-facing apps, such as iD, had to make adjustments to support this change. As a result, users running older versions of the editor may find their large changesets disappearing into thin air without any clear explanation or error message.

OSM in the media

• Game developers have integrated OpenStreetMap data into simulation games like City Bus Manager and Global Farmer, enabling players to build and manage real-world-inspired transport and farming systems while encouraging contributions to improve map accuracy.
• Gregory Thomas, of the San Francisco Chronicle, reported that Megan Gardner has ridden every publicly accessible road in San Mateo County – a feat spanning 2,800 miles. To accomplish this feat, Gardner relied on Wandrer, a social mapping platform built on OpenStreetMap data. The app turns everyday walks, hikes, and bike rides into personal quests, awarding symbolic points and rewards to users who go the farthest. Participants can track their progress and compare standings on leaderboards showing who is covering the most ground and where.

Other “geo” things

• The mapShare creators have launched a platform that lets users share and discover custom Google Maps, helping travellers find curated local recommendations such as sightseeing spots and photo locations, with strong initial coverage in Japan.
• Rainer Follador has developed ‘delta-relief’, an project designed to enhance the visualisation of SwissTopo’s LiDAR data by highlighting subtle terrain variations for easier interpretation. It has been implemented as an interactive online map, with a portion of the data from eastern Switzerland now available to the public at lidar.cubetrek.com.
