nicofr77 has developed Tisseur de Voies, a website that calculates bike loops with a return journey by train. The cycle routes come from OpenStreetMap and the national cycle-route database (France), while the basemap comes from OpenStreetMap. Journey times come from open-data timetables published by SNCF, Île-de-France Mobilités, the Provence-Alpes-Côte d’Azur region, and the Corsican Railways.
Yury Kosharovskiy has created Star Ninja, a free web map for planning a night of stargazing. It shows sky darkness, cloud forecasts, and moon visibility for any spot on Earth, using OpenStreetMap data through Nominatim (place search) and MapLibre GL JS with OpenFreeMap tiles.
OSM in action
Home Assistant 2026.10 has introduced a redesigned map built on the OpenStreetMap Foundation’s vector tile service, marking a significant milestone for its adoption by major open-source projects. The new maps features smoother rendering, dark-mode styling, improved markers, and clustering. Home Assistant proxies and caches tiles locally, reducing the load on OSMF infrastructure. The release credits Guillaume Rischard for initiating and leading the OSMF vector tile project, Paul Norman for developing the tile infrastructure, and the MapLibre, Shortbread, and VersaTiles communities.
Sebastian Mietzner has made KAIJUMIETZ, a browser game that builds any neighbourhood on Earth from OSM data and lets a giant cat destroy it in two minutes.
VivaMap, a free quality-of-life map built partly on OpenStreetMap data, now also covers the Netherlands. Four of its nine Swiss dimensions (schools, restaurants and nightlife, healthcare, and part of nature) are computed from OSM points of interest and building footprints, weighted by type and distance on an H3 hexagon grid. The aggregate scores are published as CSV under CC BY-SA 4.0.
Software
Stadia Maps shows how to build a custom map style in about 30 minutes by forking a MapLibre style, recoloring it in Maputnik, and hosting the JSON yourself, including authentication setup and common styling problems.
Stadia Maps has rebuilt its boundary processing pipeline so that each boundary retains the same disputed status at every zoom level, resulting in smaller tiles.
Heikki Kalliokoski has developed copilot.travel, a free web planner for road trips in Europe powered by OpenStreetMap data. It routes drives with self-hosted Valhalla and describes sights using linked Wikipedia/Wikidata entries or their OSM tags.
After two years of development Alexandr Lovkov has shared his web app RouteCycle, for creating convenient and engaging cycling routes. The app supports displaying landmark photos from Wikimedia Commons and Strava integration for tracking unexplored roads and landmarks.
The Wikimedia Enterprise team published an article about how CoMaps downloads Wikipedia articles to link them to OpenStreetMap data to provide offline access.
Erick de Oliveira is bringing back the OSM Smart Menu as an open-source extension for Chrome and Firefox. With a single click, it opens your current location at the same zoom level on other maps, in mapping tools such as iD, JOSM, or OSMCha, and also in Wikipedia articles containing coordinates without the need to enter any data.
Rua de Cima is a free tool for house hunters in mainland Portugal. It uses official statistics to compare ► a home’s asking price with nearby sale prices and shows walking and driving times to schools, health care, public transport, shops, and beaches. Place and road data come from OpenStreetMap, routes are calculated using Valhalla, and the basemap uses Protomaps.
Releases
GraphHopper has released version 11.1, fixing a remote code execution issue.
Nearly two months since the last report, we received a new recap of changes to openstreetmap.org. Some of these include a new version of iD (with updated tagging schema), tweaks to notes, and a new effort to track and help fix errors that were invisible to the team. But the spotlight is on the changes to visibility settings for uploaded GPX traces. These were announced back in May (we reported earlier), and have now landed for the general public, including a page that mappers can use to update their past traces in bulk in order to bring them up to the new spec.
HeiGIT announced a major release of openrouteservice with version 10.0.0, also known as Amalthea. This release focused mostly on the technical foundation of the engine. It upgraded Java and Spring Boot, reduced the set of release artefacts to a fat jar and Docker images, and moved the slim Docker image to a hardened distroless base.
Organic Maps released its September 2026 update with route optimisation, improved alternative routes, individual track hiding, and intermittent water area rendering.

I have written batch files for the Windows CLI to generate IMG files for Russia and the five Central Asian countries to make updating easier. Other tweaks include setting the maximum nodes per tile in splitter at
–max-nodes=600000
which avoids overloading the Garmin nuvi processor. Maps load faster and navigation no longer involves waiting a long time for the processor to calculate a route.
In the coming days when I have finished debugging and troubleshooting the batch files I will refresh the copies on Github.
I am wanting to buy a good handheld GPS that will provide more accurate GPS tracks than my phone. When I look at GPS tracks people have left on trails for example there will be 3-4 completely offset tracks where the trail is totally obscured by canopy so it’s impossible to plot an accurate trail.

I am wanting to buy a good handheld GPS that will provide more accurate GPS tracks than my phone. When I look at GPS tracks people have left on trails for example there will be 3-4 completely offset tracks where the trail is totally obscured by canopy so it’s impossible to plot an accurate trail.
I really prefer good open source technology without licensing and all that junk but it seems like GPS inherently requires subscription if you’re looking for accuracy. :’(
So I’m looking into Garmin’s GPSMAPS as a considerable improvement over my phones GPS accuracy. It would also be super interesting to do mapping by hand but I don’t know anything about that!
Also in the future I may be using LIDAR mounted on a drone to get high resolution scans to upload to OSM but I have done no research yet to learn how to. My LIDAR plan is to scan and more accurately map shore lines of lakes and ponds and rivers. We’ll see if that actually happens, yea right right?
OH! And I think it would be helpful to provide up to date street level imagery, I wonder if OSM or one of their partners loan something like that.. Again, yea right.

Arabic+Tamazight(Limited in some regions)+(French+English on equal foot). University still French for science and engineering with couple new branches shifted to English.
When I joined, most of name are in French. Rest all empty. As long we get more contributors, DWG will deal with a new generation. One pushed for Arabic, a decade ago. Another pushed for Tamazight, these couple years. Expecting English to come next :D.
Well for the agreed proposal:
OK for Administrative divisions: composite name.
NO for streets and places: composite name.
Too crowded for villages and town centers POI. Street names are very long. I actually want to shorten them by removing: type prefix (شارع، نهج،..), title prefix (الشهيد، المجاهد، ..), call name (المدعو ..، بن ..،). Using more language just killing it. Specially, for apps using basic view.
OK for places and businesses: street info rules.
Monitor
Some took decision, and started mass changing name to composite. That when I saw point 2 is bad idea on my town where many street are just 1-3 small blocks and small villages with a title cover it all :D. Breaking point 3, as they started changing schools and some industrial areas.
I reverted some before knowing that there was a vote and agreed decision.
Next to look for
How is affect address resolving and reverse coding? We need minimum functioning data: French and Arabic that people in business use.
Are we ready for Phonetic fill up? So All other nation fill up in their language.
I would not open new discussion until with see it through and it effect on functional side.
It seems mkgmap was updated and no longer uses sea-latest.zip or bounds-latest.zip. I had to tweak the splitter and mkgmap scripts to deal with that, and decided to create a separate script for each country in Central Asia.

N.B. The -Xmx parameter sets the maximum amount of memory the routine may use. The higher this number, the faster the program runs, but the number may not exceed available RAM on the computer. For example, if your computer has 32Gb of RAM, setting -Xmx16384m (about half of total RAM) is appropriate. If your computer has only 16Gb of RAM, use a smaller number, perhaps Xmx8192m.
I also learned the hard way mkgmap .img files will not work in Garmin Drive GPS units. The Garmin Drive GPS navigators require the NTU (new technology unicode) format and refuse to read mkgmap-generated .img files, which seem to be only in the original NT format. It was good news for my daughter, however, who gratefully accepted the Garmin Drive GPS I had bought before discovering it doesn’t like .img files produced by mkgmap.

On 13 and 14 March 2026, in celebration of Women’s Month and International Women’s Day, I had the honour of leading the “Map Your Campus” Mapillary Campaign at Far Western University (FWU) in Mahendranagar, Kanchanpur, on behalf of WOM-AsiaNavigators (Women in Open Mapping), where I serve as Nepal Lead.

On 13 and 14 March 2026, in celebration of Women’s Month and International Women’s Day, I had the honour of leading the “Map Your Campus” Mapillary Campaign at Far Western University (FWU) in Mahendranagar, Kanchanpur, on behalf of WOM-AsiaNavigators (Women in Open Mapping), where I serve as Nepal Lead. I led the campaign with Er. Niruta Neupane and it was the first initiative of its kind in Nepal’s Far Western region.
Why Far Western Nepal
Sudurpashchim Province is one of Nepal’s most remote and data-sparse regions, and its streets, pathways, institutions and community landmarks are still poorly documented in open map data. Our aim was to start closing this gap by capturing ground-level imagery and contributing it to open platforms.
What We Did
Dates
13 and 14 March 2026
Venue
Far Western University and surrounding streets
Participants
30
Method
Handheld smartphones with the Mapillary app
Result
20,000+ street-level images in two days
Day 1: Training and orientation. Introduction to Mapillary and its contribution workflow, app installation and phone setup, division into field teams, route assignment and the first field session.
Day 2: Field mapping and consolidation. Extended coverage of streets, pathways and institutional areas, quality checks on the Mapillary platform, re-mapping of under-covered areas, a group debrief, and a closing ceremony with certificates and prizes for top contributors.
Challenges and Lessons
Limited internet during uploads, battery drain during capture, consistent image quality, and changing weather and light were the main challenges. They gave us useful lessons for planning future campaigns in remote, resource-constrained regions.
Reflection
Guiding participants as they walked, captured, uploaded and mapped their own roads, schools, health posts and cultural sites showed me how communities can take ownership of their visibility. With just a smartphone, anyone can contribute to the world’s open map, and mentorship is about sparking the confidence and pride to carry this work forward. I hope this campaign becomes a replicable model for campus-based street mapping across Nepal.

Far Western University, Bhimdatta (Mahendranagar), Kanchanpur: approx. 28.917° N, 80.333° E (view on OSM)

The sprint ran from 5 November to 5 December 2025.
I was assigned to map two rural municipalities on my own:
The sprint engaged skilled Advanced OSM mappers to improve geospatial data in 18 priority municipalities across Madhesh and Lumbini provinces. Mappers contributed to the mapping and validation of land use and land cover, buildings, roads, waterways and points of interest, following the standardized OSM guidelines for Nepal. Mapping was done using Esri World Imagery.
The objectives were to:
Map essential features such as land use and land cover, buildings, roads and waterways
Engage youth mappers and OpenStreetMap enthusiasts in remote mapping
Enhance data accuracy, consistency and completeness in municipalities
Strengthen open-source geospatial data for local resilience

highway=cycleway - основной тег линии, который указывает, что путь предназначен для движения на велосипедах.
foot=no - явно запрещает движение пешеходов (если пешеходам запрещено находиться на этой дорожке). Если пешеходы разрешены, но дорожка разделена на зоны, используют foot=yes и segregated=yes/no.
Велосипедная дорожка + тротуар:
Комбинация тэгов для обозначения пешеходного тротуара, совмещённого с выделенной велосипедной дорожкой, которая конструктивно или визуально отделена от пешеходной зоны:
highway=footway- обозначает, что данный объект является обустроенной дорожкой, предназначенной в первую очередь для пешеходов.
footway=sidewalk - уточняет тип пешеходной дорожки. Этот тег указывает, что дорожка является тротуаром, то есть идет параллельно автомобильной дороге (обычно повторяя её геометрию).
bicycle=designated - указывает на официальный юридический статус для велосипедистов. Это значит, что дорожка специально выделена/предназначена для движения на велосипеде (например, установлен соответствующий знак или нанесена разметка), а не просто «разрешена для транзита».
segregated=yes - означает, что потоки пешеходов и велосипедистов разделены. Это может быть реализовано с помощью сплошной конструктивной разделительной полосы, разметки на асфальте или использования разных типов покрытия (например, плитка для пешеходов и асфальт для велосипедов).

Earlier this year we introduced a sandbox feature within Humanitarian OpenStreetMap Team Tasking Manager, providing a safe space to practice and experiment with the OpenStreetMap data model. This is built on the foundational work from OpenStreetMap US!
Beyond practice and data privacy, Sandbox setup is already proving to be a data annotation tool for machine learning workflows. Using sandbox, you can capture custom, non-standard schemas and training labels (like marine habitats or specialized features) without conflicting with live OSM data.
Looking ahead, we plan to extend this sandbox environment to handle data conflation, allowing users to bring in external datasets at the task level to compare, validate, and reconcile geometries and attributes against OSM.
A huge thanks to OpenStreetMap US, as well as Sam Woodcock, Kshitij Raj Sharma, Prabin Pathak, Sumit Dahal, Anil Raj Rimal, DK Benjamin, and everyone across the community who contributed to designing, testing, and reviewing this feature.
If you run workshops, train mappers, or work with experimental datasets, please test out the Sandbox on the Tasking Manager and let us know your thoughts or feedback!

Because this question comes up again and again, I would like to document the answer here in a little more detail.
A garden house that was added two months ago to the OSM database is not displayed on a map at certain zoom levels, even though the underlying map data should actually be up to date. In my example, the problem was reported both in the GitHub repository of the map and in the GitHub repository of the German map style.
However, the map at karte.openstreetmap.de requests the tiles in exactly the same way as any other map that uses tiles from tile.openstreetmap.de: it retrieves them from the tile server tile.openstreetmap.de.
So, if you can rule out problems such as a local browser or map cache, troubleshooting continues at tile.openstreetmap.de.
New OpenStreetMap data should ideally become visible on tile.openstreetmap.de within a few minutes. After all, one of the most important tasks of the German tile servers is to show OpenStreetMap contributors as quickly as possible whether their changes have correctly arrived in the database.
This happens in two steps.
Keeping OSM data up to date
Database
The databases of the German tile servers are continuously updated via osm2pgsql using the latest OpenStreetMap data.
The current state of the database update can be seen directly below the map.
The displayed time is UTC. In Germany, this means that during daylight saving time the displayed time is two hours behind local time, and during standard time it is one hour behind.
It is also worth knowing that, for redundancy reasons, two servers are behind tile.openstreetmap.de. Currently these are Cassini and Bonne. The website indicates in its heading which server you have reached.
This is important when troubleshooting: a problem can occur on only one of the two servers while everything is already displayed correctly on the other. This can be particularly confusing.
Prerendering
Even if the database is up to date, this does not necessarily mean that every map tile being served contains the latest data.
The reason is so-called prerendering: map tiles are not rendered from scratch every time they are requested. Once a tile has been rendered, it is reused until a database update determines that it needs to be rendered again because of a change.
An outdated tile is not deleted immediately. Instead, it is marked as dirty.
When a tile is marked as “dirty,” a technically very simple but efficient trick takes place: the system does not delete the tile; instead, it changed its age on the server’s filesystem. When a tile is generated normally, the server stores it with the current timestamp. A tile marked as dirty, however, suddenly has the file date January 1, 1970, while remaining in the same directory. When a user scrolls to exactly this region in the browser, the following happens:
[Browser requests a tile]
│
▼
[mod_tile checks the tile file]
│
├──► Is the tile newer than the latest relevant DB update?
│ │
│ └──► [Serve the tile immediately]
│
└──► Is the tile older than the latest relevant DB update?
│
└──► [Serve the tile and mark it as DIRTY]
This has an important advantage: if the servers are heavily loaded, they can continue to serve existing, even if potentially outdated, tiles.
This keeps the map display as performant as possible even under heavy server load and avoids unnecessary blank areas.
For most users, this is a sensible compromise. Sometimes, however, a mapper needs to see the current state of a particular location immediately.
Requesting new OpenStreetMap.de tiles
When I read the issue linked above, I therefore looked at the affected location directly on both tile servers:
This is not ideal. As described above, however, it is a deliberate compromise. If the servers are heavily loaded, not every change can be rendered immediately on every server. Otherwise, significantly more computing resources would be required, or one would have to accept that the map becomes slower more frequently or that areas that have not yet been rendered appear as blank areas.
Sometimes, however, a mapper needs to see the current state of a particular location. To do this, they can request more infos of the corresponding tile via the context menu on tile.openstreetmap.de.
Infos about tile
When viewing a particular tile on tile.openstreetmap.de, you can open a context menu with the right mouse button. It provides an option to retrieve further information about the tile.
Clicking Kachelinfos shows detailed information about the tile:
The tile on Cassini was rendered in May:
https://cassini.openstreetmap.de/19/275933/172159.png/status: Tile is clean. Last rendered at Mon May 11 14:10:07 2026. Last accessed at Fri Oct 02 18:14:45 2026. Stored in file:///var/cache/tirex/tiles/osmde/19/66/58/80/215/136.meta (Dates might not be accurate. Rendering time might be reset to an old date for tile expiry. Access times might not be updated on all file systems).
The tile is therefore still based on an outdated data set and is waiting to be re-rendered.
The behavior (Do not regenerate it immediately if the server is under heavy load.
) can also be understood from the source code of mod_tile.
Conclusion
On the German OpenStreetMap tile servers, mappers have the option of requesting infos for a specific tile.
The OpenStreetMap data is continuously imported into the database.
Changes invalidate the affected tiles and mark them as dirty.
When the servers are heavily loaded, older, already existing tiles continue to be served.
So if a change is not yet visible, this does not necessarily mean that the OpenStreetMap data has not yet been updated or that there is another problem. It may simply be that the server is currently busy.
