The main improvement in this release is the support for shared corner fillets. Now, when two open ways meet at a junction, the rounding applies across both ways as a single continuous operation.

For the moment the wiki only describes the tagging of protected heritage in the four Belgian regions that get the heritage=4 tag. In Flanders, Wallonia and Brussels, the heritage agencies also maintain a (more comprehensive) inventory of heritage next to a list of protected heritage items. (the situation in the German speaking region isn’t well known by me). For example in Wallonia, the heritage inventory lists 51,000 items, including 9,000 protected items.

This is a proposal to follow the practice of heritage agencies and assign a tag to all inventoried heritage objects: add a tag for heritage objects inventories: heritage=5 * This will make the heritage items included in an inventory identifiable and searchable. Until now not protected inventoried heritage in Belgium only get the tag historic=x as other “old” items. * A tag for items that are only in their inventory is already in use by OSM France and also Italy, Netherlands, Bulgaria, Hong Kong also have different types of the tag heritage. (In Belgium we use heritage=4 for protected heritage as some other countries but a lot of other countries use heritage=2 for protected heritage. The used number is specified per country). * The wiki now describes heritage as “Site/building/object registered by an official heritage organisation”.

In the last few years, there have been a number of changes at the heritage agencies in Flanders and Wallonia.

Wallonia The agency AwaP (Agence Wallonne du Patrimoine) has, next to the ‘’Patrimoine culturel immobilier classé’ for protected heritage, an inventory of that is now called IRP Inventaire Régional du Patrimoine (until recently it was named IPIC Inventaire du Patrimoine Immobilier Culturel, a name that can still be found in many OSM entries). It is interesting that heritage objects in OSM include a link (with a URL) to the Walloon IRP inventory, as this contains a detailed description and history of the item, as well as a reference to its status as a protected and exceptional site, if applicable. That description and history appear only in this inventory and not in the inventory of protected heritage, which only provides a very limited justification for the decision to protect the site. With the proposed additional tag for heritage, items in the IRP inventory get heritage=5 but protected items still get heritage=4.

Brussels The situation appears to be similar to that in Wallonia with an ‘Inventaire du Patrimoine Architectural Bruxellois’and ‘Le registre du patrimoine protégé’.

Flanders 1. There is a scientific inventory of heritage objects “Erfgoedobjecten” containing a fairly detailed description and history of the item. There are no legal consequences of being included in that inventory. It would be a good idea to include that link at the item in OSM so that anyone interested can find the explanation. The URL contains the word “erfgoedobjecten” and links to the description, with links to the “Aanduidingsobject” and its protection if applicable. 2. Indicative objects “Aanduidingsobjecten” are recognised architectural heritage and imply legal consequences that can be limited or extended if they are protected heritage. The proposal is to assign in OSM the tag heritage=5 to these heritage features and heritage=4 to protected heritage features. Tagging the URL to the Aanduidingsobject is less valuable as it includes very limited information about the object. The URL to the Erfgoedobject is more interesting. Including the ID number in the tagging is valuable to trace back a heritage item. There are heritage objects that are not listed as “Aanduidingsobject” mostly it are landscape features but it can be architectural feature. If applicable they can get the tag heritage=6.

German-speeking Community The situation isn’t known to me.

Question about this propasal: Are there objections or remarks against the proposal to add the tags heritage=5 and heritage=6 for heritage tagging in Belgium? Are there objections or remarks to make a wiki about heritage tagging in Belgium as described above and change menu’s in JOSM and eventually ID?

Two years of experience as editor for Brazilian Portuguese at weeklyOSM: some highlights from this period

Self explanatory, but I am doing a bit of micromapping and working on accurate representations of buildings and parks in the roodepoort area, close to where I work.

Hey there!! Im Rupam Golui.. though most people online know me as Agasta and I honestly prefer that. Im a 2nd year CS undergrad from Kolkata, India. Most of my time these days goes into open source and projects (GitHub: Itz-Agasta).

Hi! I’m Sherley Sonali, a CS undergrad from IIIT Hyderabad, India. As part of GSoC 2026, I’ll be working on Valhalla RAD with my mentors Nils Nolde, Kevin Kreiser, and Christian Beiwinkel.

The project

Routing engines are quietly complex and a code change that looks small can silently make routes worse in ways unit tests never catch. RAD gives Valhalla maintainers a way to see exactly what changed in routing quality when a PR lands, and make an informed call before it merges. The system brings together a route request generator, a GitHub Actions pipeline that diffs results across router and graph versions, and a React web app where maintainers can inspect those diffs and decide.

A bit about me

I got into routing through Fleetix, a vehicle route optimization platform I built during an internship and it used OSRM to compute multi-stop routes over OSM data for real employee transport operations. Seeing how much the engine’s interpretation of the map mattered in practice, and what happens when it goes wrong, is what drew me toward Valhalla and eventually toward this project.

Where we are

The coding period has kicked off, the initial project setup is in place, and work on the request generation pipeline is underway. I’ll be using this diary to share progress and lessons learned as the project evolves.

Hi!
My name is Francisco Albacete Chicano (but feel free to call me Paco!), and this year I have been selected for the GSoC 2026 with OSM, working on Valhalla Enhance Pedestrian routing project with my mentors Kevin Kreiser and Christian Beiwinkel.

GSoC'26 : DuckDB Backend for Martin TileServer

I’ve been adding ALPRs throughout the region in my community and, first of all, wow there is so many of them. Second I am aware of what Flock cameras look like but I am unable to figure out who owns / creates the other more squat looking ones. If anyone has any information on how to identify the other cameras please let me know, I’d like for my information to be as accurate and precise as possible!

How dare you cast aspersions on and try to obstruct me and my work on OpenStreetMap in Victoria, BC. I thought OpenStreetMap was supposed to be collaborative, but instead you proceed to misrepresent my statements and get openly hostile and destructive toward my efforts. Now I must demand that you cease all further interference with and circumvention of what I am trying to do. I will not have it.

For quite a while now, I have been thinking about making a tutorial on mapping lifting stones. In case you are not familiar - this is a tradition throughout parts of Europe (VERY strong in the Basque country), but also in Asia and North America.

Earlier this month my husband and I drove by or through a number of small communities in Northern California as we were headed to and from Canada. One of them was Grenada. I was curious to see if it was mapped on OSM. It wasn’t, save for the streets (including some erroneously added ones).

So I’ve spent my mapping time this month on Grenada. And now the buildings and addresses are there.

We all gave OpenStreetMap a try once, no? Same for me. No idea how old my (old) account is. I havent used it for years, and I wasnt able to re-enable it again but in Autumn 2024, a friend told me about StreetComplete.

Problem with foot=no on lawfully forbidden streets(Train-Crossing). not verifiable on the Ground

Easy way to find Speed Limit data for Motorways (Highways), Trunk roads, and Primary roads in United States of America

That day, I received this email.

I grew up in Nepal. Hills everywhere. Roads that don’t exist on any map. Communities that satellites can barely see through the cloud cover. When I first heard about OpenStreetMap, I thought: this is exactly what those places need.

That was a few years ago. Since then I’ve spent over 300 hours mapping, not because someone paid me to, but because I kept thinking about the person who might one day need that road to exist on a map before they could get help.

How I Started: Before I knew what OSM was, I was already messing around with maps, visiting new places, uploading photos to Google Maps, adding names, leaving notes about locations. I liked documenting places. That habit slowly turned into something bigger.

A hackathon in college introduced me to humanitarian mapping. That’s when it clicked: mapping wasn’t just a tech thing. It was about making communities visible.

My background is electrical engineering. My job is in the cable car sector. Neither screams “mapper.” But when you work in mountain infrastructure, you see how much depends on accurate geographic data, withdrawal routes, access to remote villages, disaster response. The gap between what exists on the ground and what exists on a map is sometimes jarring.

I’ve actually validated more tasks on HOT than I’ve mapped myself, which felt strange at first. But validation matters as much as mapping, maybe more. A wrong building polygon in a flood response map doesn’t help anyone.

On Women and Mapping: Most mapping events I’ve attended, online or in-person, are heavily male. So is the leadership in local OSM chapters. But whenever a woman shows up and starts contributing, the quality is often excellent. Careful, methodical, detail-oriented. And then they disappear. Not because they lost interest, usually because no one made space for them to stay.

OpenHerMap changed something about that. I watched women across the Asia Pacific region build their own mapping networks, train each other, and take on projects the broader HOT community ended up relying on.

I think about the Nepal Red Cross Missing Maps project, 65 tasks covering Bhajani Municipality. Remote, underserved, barely visible on any mainstream map. The communities there include women who walk hours to reach health clinics, children who cross unmapped rivers to get to school. When those paths get mapped, it’s not abstract. It’s someone getting somewhere safely.

What Mapping Taught Me That Engineering Didn,t: Engineering taught me precision. OSM taught me that precision without inclusion is incomplete.

A map built only by people who look like me, engineers, men, people with reliable internet, will have gaps. Not intentional ones. Just the natural result of mapping what you can see and know. Women map differently, not because of some essential quality, but because their daily routes, their safety concerns, their infrastructure needs are different. A market that women use every morning may not appear on a map if no woman was ever asked to trace it.

I tend toward roads and buildings because that’s what humanitarian projects prioritize. But POIs, shops, health posts, water sources, safe gathering points, that’s where local knowledge matters most, and local women often hold that knowledge.

Where I Am Now: Today I’m an Advanced Mapper on HOT with over 300 hours of contribution. I still work in the cable car sector. The mapping happens in the margins, evenings, weekends, lunch breaks.

The theme of this competition is “Women and Mapping in OSM.” I’m a man writing about it. That might seem odd. But this isn’t only women’s work to do. Making open mapping more inclusive requires everyone to notice the gaps and then do something about them.

The map is never finished. That’s the point.

Just after the midnight of May 21 to May 22, 2026 the 5000th daily planet diff was generated.

Tonight I finished mapping every building, every address in Farley Iowa. There are still buildings and farms outside the city limits but that’s a future project.

While preparing this article, I wanted to export the coordinate data of the battlefield map that I created in Altilunium LocationPad to GitHub Gist.

For the first time, Humanitarian Data Exchange (HDX), a widely used platform for sharing humanitarian data, is releasing disaster-specific OSM datasets.

Issue #1 when first using offline OpenStreetMap navigation apps for Android, such as OsmAnd, Comaps, and Organic Maps: the size of the map to be downloaded. In many places, it’s the entire country or nothing.

Over the last few weeks Ive improved the way that paths and tracks are shown on map.atownsend.org.uk in both the raster and vector versions. The aims were:

Contributing commercial vehicle GPS traces from Kerala — a routing approach

I’ve been working on a method to convert commercial vehicle telematics data into useful GPX traces for OSM contribution in Kerala.

The problem

Telematics data is segment-based — each record has a start coordinate, end coordinate, timestamp and distance, but no continuous GPS track in between. Uploading these directly produces straight lines which aren’t useful for mapping.

The solution

I set up a local OSRM instance using the Kerala road extract from Geofabrik, then route-matched each segment to the actual road network. This produces GPX traces with thousands of road-following points instead of straight lines.

Results

From two months of data covering Thrissur, Irinjalakuda, Chalakudy, Kodungallur and surrounding areas:

• 141 road-snapped segments uploaded as GPX traces
• 19 high-priority segments flagged as possible unmapped roads
• These will be cross-checked against aerial imagery in JOSM

Next steps

Reviewing the unmapped road candidates in JOSM against Bing aerial imagery. More vehicle data from the same region will be processed and contributed regularly.

If anyone in the Kerala OSM community has experience with similar data or wants to collaborate on reviewing unmapped road candidates, feel free to reach out.

First time writing a diary so friend I converted to mapping can find me :D

A special opportunity: presenting OpenStreetMap to the Pedagogical University of Maputo (Mozambique)

Yesterday I cleaned up some map data by removing unnecessary email and unrelated details from several objects. I am learning and trying to follow proper OpenStreetMap mapping guidelines.

[This is a work in progress, IANAL and this isnt legal advice]

My name is Chukwuemeka Emmanuel Nwosu, a 300-level student of the Department of Geography and Environmental Management, University of Port Harcourt. This diary documents my Industrial Training (I.T.) programme as I undergo it.

After careful thought, deliberation, and counsel from my mentor and my brother, I decided to carry out my I.T. programme at the Mapathon Center of the Unique Mappers Team, University of Port Harcourt. I officially resumed on Tuesday, the 11th of May 2026.

On my first day at the Mapathon Center, I had the pleasure of meeting several interesting individuals who, like me, were present for their Industrial Training. Among them were Matel, who serves as our I.T. representative, and Wisdom, both students from the Department of Geology, Rivers State University, and two of my coursemates from the Department of Geography and Environmental Management: Rania and Obasi Emmanuel. I also learned of a few other trainees I had yet to meet in person.

Notably, I was able to complete a part of the week’s assigned task on this very first day. The task required me to create a map of the University of Port Harcourt, situating it within the context of Rivers State and Nigeria as a whole, while clearly indicating the locations of Abuja Park and Delta Park within the university.

I got into looking into maps and understanding where everything is. I’m at the point where if I’m at a location I’ve never been before, I will start looking all around me and then using my brain to put everything into OpenStreetMap. I love this website. It’s like a passion project when nothing else sounds fun. Anyway… The point of this Diary is all the changes I added to different locations around the northern parts of Minnesota and Wisconsin. Here is what I wanted to update users past and present on what changes I made.

I want to thank the community for not deleting @MidwestMapGeek’s building outline. Today, I came here to fix what is the updated version. My goal is to help Semi Drivers and anyone trying to get to this company’s site. You are amazing @MidwestMapGeek

• Used Bing Maps Aerial to redraw buildings

– Changes – -Deleted outline of the building -Reworked the new outline for the company -Added another outline for a building next to an existing building -Reworked the rail system so it is clear the the train goes through (underneath) the building -Reworked the road leading to the building site (TPWS) -Added the scale shack that the site has -Finally added a “point” for anyone that is going to TPWS -hours, website, and location are added // note: the address that was given to the company is technically another access point to get inside but from what I heard, you can’t access from there and have to go underneath the bridge near Graymount

Generally speaking, Lifecycle Prefixes mean that when something is no longer in use, a tag such as gets changed to . That should be straightforward, but sometimes creeps in.

Welcome to my first entry in OSM.

I have been quite interested in being here every once in a while, it actually helps the fact that there’s a map that needs constant updating and can actually do something.

So far, from what I’ve done within my local city of London, Ontario, I finished up:

• New Plaza at Fanshawe/Highbury
• Bus routes
• Road classification
• Fixing of OSM notes
• Coveted new developments at the South and West sides of the city.

Im not surprised that theres alot more for me as an individual to explore, nothing much and thats just all.
