Mapping

• Comments are requested on this proposal:
  • data_center:tier, data_center:total_power, data_center:IT_power, data_center:IT_area, proposed by LunaLune, to extend telecom=data_center features with standardised technical attributes such as redundancy tier, total power capacity, IT load (or the maximum electrical power available for IT equipment, as servers, storage, networking), and usable IT area (or the total floor area exclusively used for IT equipment).
• ‘Aerodrome Descriptive Tags’, proposed by Telegram Sam, is up for vote until Tuesday 26 May, which aims to add descriptive tags for aerodrome=* and better describe these features. It proposes distinct tags for type, usage, access, sport, and international traffic, as well as dedicated values for airstrip, heliport, and seaplane_base.

Community

• In a video Anne-Karoline Distel showed which objects hikers can add to OpenStreetMap, while on the trail, using OsmAnd. Examples include benches, route markers, viewpoints, shelters, fords, and safety-related facilities.
• Raquel Dezidério Souto published, on her OSM user diary, about her participation as a special speaker at an event organised by the Pedagogical University of Maputo (Mozambique), which discussed changes to the country’s environmental law. During the event, she took the opportunity to highlight the importance of open data and the use of open collaborative mapping platforms, with a special focus on OpenStreetMap. A copy of the special keynote entitled ‘Development and Conservation’ is available on Zenodo.org.
• 9tab wrote about some addr:place inconsistencies on the OpenStreetMap Wiki. Use of the addr:place key can differ from the (contradictory) descriptions in the Wiki, notably in relation to the addr:street key.
• A new two-year comparative study in Denmark demonstrates that the Danish OSM community produces geodata roughly nine times more efficiently than the government-led GeoFA project ►. Based on a two-year tracking of 38 distinct outdoor and cultural data categories, OSM Denmark maintains a significant lead, accounting for over 145,000 recorded items.
• In their latest OpenStreetMap interview series, OpenCage spoke with Volker Krause about Transitous, an open platform for public transport routing.
• The MapComplete project reported that more than 20,000 changesets have been created with the tool in 2026 so far. At the same time, the panoramax=* key has surpassed 100,000 uses in OpenStreetMap, most of them added via MapComplete and linking to content in the Panoramax ecosystem.
• As reported by Ivan Branco on the OpenStreetMap Community forum, on 1 May, the twelfth issue of mensileOSM , the Italian-language monthly newsletter for Italy’s OpenStreetMap community was published. This issue also marks the project’s first anniversary.
• Thomas D. has started a discussion on the OpenStreetMap Community forum about possible collaboration between the OpenStreetMap community and the organisation Open Lunar Foundation on an open-source Moon map. The initiative is motivated by renewed lunar activity and existing ideas around collaborative mapping of the Moon.
• OpenStreetMap US is collaborating with the Environmental Policy Innovation Center on OpenWetlandsMap, an open dataset of wetlands in the United States. The project aims to complement outdated and fragmented data with up-to-date, community-driven OSM mapping to support conservation and decision-making.
• Using Altilunium Locationpad, rphyrin has created some maps representing the 2018 journey of a Hajj pilgrim group, tracing the pilgrims’ route from departure to completion.
• Andy Townsend explores what the lifecycle tag disused=yes in OpenStreetMap actually means.

Local chapter news

• OpenStreetMap US has welcomed the Yesterdays as a new Charter Project. The platform enables volunteers to georeference historical photographs and collaboratively map past cityscapes using OpenStreetMap and historical sources. The project began in Richmond, Virginia, where the Charter Project Advisory Committee is based.

Events

• The OpenStreetMap Foundation has made a call for bids to host the 2027 State of the Map conference. Applications are open until Sunday 19 July, with the selected host to be announced during SotM 2026 in Paris.

Education

• The 2026 ‘OpenStreetMap Workshop Series’, organised by IVIDES DATA (Brazil), has kicked off with participants from Portuguese-speaking countries Brazil, Mozambique, and Angola. The organisers have made available a PDF copy (in Portuguese) and a link to the presentation video, as well as the uMap showing the home cities of the participants.

Maps

• David Smith recounted his six-year-long journey designing the OSM-based map in Pedometer++, a walking tracker for Apple watchOS, built with help from Andy Allan.
• Transform Transport has published an interactive ’15 Minute City Score’ map analysing access to essential services across European cities. The analysis uses OpenStreetMap data for pedestrian networks and amenities, applying consistent spatial methods for comparability.
• Using the OSM-ALKIS address comparison web app, Alex Spritze analysed the distribution of missing address data across Saxony-Anhalt. The results highlighted significant disparities between municipalities, ranging from high-performing areas such as Ingersleben, which has ‘only’ nine missing addresses, to municipalities like Güsten, where just 3.8% of addresses are currently mapped in OpenStreetMap.

OSM in action

• The Syrian Ministry of Tourism has developed the Syrian Tourist Map, a web map based on OpenStreetMap data that shows the locations of attractions, tourist facilities, and investment opportunities in Syria.

Software

• HeiGIT presented its new Traffic Emissions tool in the Climate Action Navigator that combines OpenStreetMap road data and machine learning to map road traffic-related CO₂ emissions and air pollutants at street level across Germany, helping cities better understand where climate action is most urgently needed.
• Grid2Poster is a new open source tool that renders electrical transmission networks from OpenStreetMap data as print-ready posters. This Python-based project uses GeoPandas, OSMnx, and Matplotlib, and supports country, regional, and continent-scale maps with transmission lines, cables, and optional administrative boundaries. The project is heavily inspired and reused styling from maptoposter.
• Tobias Jordans has released Grenzabgleich, a web tool comparing OpenStreetMap administrative boundaries with official datasets in Germany. It calculates metrics such as IoU and Hausdorff distances to highlight discrepancies and help mappers prioritise review and improve boundary data quality.
• The OpenStreetMap-based project CoMaps reported major technical updates, including migration to Swift and Material 3 and automated map generation. The goal was improved maintainability, performance, and long-term sustainability for the app.
• CoMaps celebrated its first birthday and the team has looked back on its growing community, big new features and what comes next.
• HeiGIT presented the new user statistics available in ohsomeNOW, giving OpenStreetMap users deeper insights into contributor activity histories and supporting the analysis of organised editing patterns.
• The OpenStreetMap Operations Team has heavily rate-limited QGIS’s access to tile.openstreetmap.org after bulk tile usage risked disrupting the service for other users. The OSM and QGIS teams are working on ways to separate bulk downloads from normal interactive usage. OpenStreetMap is also seeking donated servers to expand tile rendering capacity.
• Sean Carapella has launched PaddleMap, a routing and mapping tool for watercraft built on BRouter and brouter-web. It supports routing along waterways and portages and highlights paddling-related POIs such as access points, dams, and rapids.
• Trailmaps.app is a new web project that turns OpenStreetMap data into mobile-friendly offline maps of mountain bike trail networks. These maps are designed to match local trail signage instead of generic difficulty colouring, and the related map generator has been published as open source. According to the developer, the entire project was largely created with the help of Claude AI.
• A new userscript now allows users to add multiple custom background layers to iD. Instead of switching a single custom URL repeatedly, mappers can now easily toggle between several tile sources.
• Manny Fred has introduced HydrantMap, a new web project created by Fabian Flodman to visualise and maintain hydrant data from OpenStreetMap. The platform was inspired by the idea of OsmHydrant, focusing on up-to-date data, mobile usability, and a maintainable, modern technical foundation.

Programming

• darkonus invited JOSM users to test their ‘Fillet Tools’, a plugin that can round way corners, similar to the fillet tool in CAD software. The author is seeking feedback, bug reports, cases of unusual behaviour, and suggestions. The plugin can be installed manually from the version 0.1.0 release on GitLab.
• Matija Nalis shared his experience of setting up a Panoramax instance for OSM-HR, including hardware, Docker setup, and OSM OAuth2 integration. His report provides practical insights into deployment, operation, and challenges of hosting image infrastructure.
• Christian Quest has shared concrete figures on the memory requirements for a Panoramax instance on the Forum GéoCommuns. The analysis shows that 360° images in particular significantly increase the demand and memory optimisations are planned.
• The OpenStreetMap Operations Working Group has updated the Nominatim usage policy. The changes further restrict automated usage and introduce initial guidelines for AI applications and ‘vibe coding’. Reselling geocoding results from Nominatim is now prohibited.

Releases

• Nico Isenbeck’s onroutemap.de underwent some improvements in March and April:
  • March: The software was made available in French and Spanish and personal favourites can now be exported as KML and GPX.
  • April: The addition of a real-time wind gust layer on the map with current gust (Open-Meteo) speed and direction, colour-coded according to the Beaufort Scale. The most important new feature, however, was the migration from Overpass to PostGIS, resulting in much better map generation performance.
• Marcus Jaschen hinted at several new updates for bikerouter.de coming in version 2026.11.
• Martin Raifer tooted about the release of iD 2.40, which introduces a new style for shared bicycle and pedestrian paths and dynamic detail levels for circular features. The update also changes preset handling, automatically removing tags that are not valid for the newly selected preset.
• The OsmAnd team has released version 1.03 of OsmAnd Web. New features include Garmin Connect integration for automatic activity syncing, ‘Smart Folders’ for tracks, improved POI information, and redesigned tools for managing and displaying GPX tracks and favourites.
• The OSRM project has released version 26.5.0 of osrm-backend. This release added Python bindings to the main repository, migrated the build system to vcpkg, reduced Boost dependencies, added support for winter_road and ice_road in routing profiles, along with many other improvements.
• Project OSRM tooted that they are experimenting with an isochrone endpoint. The feature has not yet been released but could in future support reachability analysis based on OSRM routing.
• Martijn van Exel has released version 0.8.2 of his Python Overpass library. This update now requires applications to set a user-agent header, helping to protect the Overpass API from problematic requests.
• CoMaps released version 2026.05.06. From this version onward map versions will no longer be hard-tied to an app version, allowing users to update their maps without first having to update the app. This will allow for an increased update frequency for maps, which will now be weekly.
• The Organic Maps team has released version 2026.05.08-4, which now allows you to view public transport routes at stops on a map. It also includes updated OpenStreetMap data, improved elevation charts, optimised map downloads, and many other improvements. You can read the detailed announcement on their blog.

Did you know that …

• … there is a browser extension that adds an ‘Edit Tags’ button to every object on osm.org?

OSM in the media

• CHIP has published a commentary describing ► OpenStreetMap as much more useful than Google Maps when looking for nearby places in an unfamiliar area. The article says OSM shows more detail about shops, places, and amenities, while Google Maps leaves visible gaps in the example used.

Other “geo” things

• Caleb Robinson and Isaac Corley have blogged about using a Gaussian splat approach to sharpen images from Sentinel-2. The method works by using the slight variation in the location of pixels between the different passes of the satellite to extract more information from the images.
• The Ordnance Survey and GeoPlace have demanded the removal of millions of openly published UK council tax address records, claiming intellectual property rights on behalf of the Ordnance Survey, GeoPlace, and the Royal Mail. The affected datasets had previously been released under open licences by 57 local authorities.
• The latest Garmin TopoActive Europe 2026.10 map update, based on OpenStreetMap data, is causing serious routing issues on multiple devices, including crashes ► and boot loops. Several Edge models are affected; as a workaround, Garmin currently recommends downgrading to an earlier map version.

We welcome link suggestions for the next issue via this form and look forward to your contributions.

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

1. Improve clarity, so that their visibility in e.g. nondescript woodland was better
2. Improve consistency, so that the display of them on vector and raster looked similar to each other, and the “visual weight” of each class broadly matched when looked at together on a map.
3. Reduce confusion so that two different things were not shown in similar ways.
4. Show “good quality” paths and tracks (e.g. paved and compacted gravel surfaces) differently to other ones to help answer the “will it be muddy” question.

First, a bit of background: England and Wales don’t have a general right of land access like “allemansrätten” in Sweden or the Scottish Outdoor Access Code in Scotland. It does have a series of rights of way, which are recorded in OSM with the designation tag. Knowing this is key to knowing where you can and can’t go, and what you can and can’t do there. Maps of England and Wales often show these different access rights in different colours. OpenStreetMap’s tag names footway and bridleway were also influenced by the names of these legal access rights.

The map schema that I use defines classes its “transportation” layer as follows:

• Public roads (motorway through unclassified and residential) that broadly match OSM’s tagging
• Other rights of way (“unclassified county roads”** through footway). The designation tag in OSM used to determine what goes where.
• Other ways where there may be access, but no right of way (service, paths and tracks with no designation)
• Other oddities also not generally part of any routing graph like gallop, leisuretrack, raceway, construction.

Secondly, there are a limited number of ways that you can use to help users tell between similar things (such as linear paths) on a map:

• colour
• width of line
• dashes and dots in the line

Consistency was improved just by going through each of the visual elements in the vector and raster styles and handle them all in a common vector or raster way. The technologies are very different - Mapnik (raster) and MapLibre (vector) do have different approaches, so there are still style differences between maps, but I’ve done what I can without a ground-up rewrite of the raster maps based on the vector approach (for which life is just too short). A glance at Cannock Chase in vector and raster shows a big improvement on what went before.

In order to address the first aim (clarity) and the third (reduce confusion) I made all the path representations that I use slightly wider, and made them all out of slightly longer dashes and used dashes rather than dots. The latter was important to avoid clashing with disused rail on raster.

Previously I’d shown restricted byways the same colour as bridleways but with a different dash pattern. I changed this to a new colour [half-way](https://map.atownsend.org.uk/maps/map/map.html#16/-24.9952/135.1561 between “bridleway blue” and “BOAT / UCR brown”. This improves consistency and frees up “different dash patterns” to be used for better-surfaced paths and tracks.

Finally, in order to be able to show “good quality” paths and tracks differently to “normal” (potentially muddy) ones I used a slightly different dash array, consistently across each path and track type:

“Normal” paths and tracks have dashes all the same length (but wider paths and tracks have longer dashes than narrower ones). “Good Quality” ones have alternating normal and longer-length dashes. At the location of the picture at the top of this post (here in OSM) you can see a restricted byway running north-south and a bridleway running east-west. The southern part of the restricted (wide) byway and the western part of the (narrow) bridleway are both better quality (both surface=compacted in OSM). You can use the vector debugger to investigate further.

You’ll also notice from the raster legend that some paths, footways and bridleways can also be shown as “less visible” - this is used for informal paths and for those where the trail_visibility tag is set to a lower value. Completely invisible paths with no designation (along with some of the highest sac_scale ones) are in the schema as “bad” paths, and only shown on map.atownsend.org.uk via a separate raster overlay (“no vis paths”):

(see here in OSM)

** I probably need to write something somewhere about the different designation values used on highways in England and Wales, but there’s not really room here.

Недавно добавляя заметки чтобы потом по ним добавлять что-либо (ну или проверить место) одну заметку случайно оставил открытой, там я написал “Лево от 7 столба мусорка”. Я даже не мог представить насколько агрессивные местные энтузиасты. Сейчас заметки уже нет (больше месяца прошло с её закрытия) но извините, я не знал что люди умеют лить столько говна за мелкий текст. Хватало мне неделю не заходить на осм так сразу! Люди меня обзывали всем чем только можно, говорили “Смысл этой заметки? Удались!” и “ГНИДА” (просто по приколу походу. Чем я так людей оскорбил? Там на месте бывшей мусорки кто-то машину припарковал? В чём прикол срать без причины?

Ada sedikit cerita tentang hal buruk yang saya alami waktu beraktivitas di jalan raya. Tahun 2015 klas1 SMA, jalan menuju sekolah ada kejadian tidak mengenakkan, saya mengalami kontak fisik dengan orang yang tidak saya kenal, itu terjadi di jalan raya dan sekitar 2 meter dari rumah saya, dimana ada 5 orang dan 2 dari mereka melakukan kontak fisik kepada saya, tanpa izin saya. Saya kembali pulang kerumah dengan keadaan menangis. Ketika saya kasih tau orangtua saya, mama saya langsung pergi cari orang-orang itu, dan menjeput saya di sekolah. Ada salah satu teman saya perempuan juga, yang menormalisasikan perbuatan tersebut dan berkata itu hanya memengan tanggan saja. Apakah saya yang terlalu berlebihan? Tapi itu tempat umum mereka berani, bagimana dengan tempat sepi, apakah mereka tidak akan berbuat lebih dari itu? Oleh karena itu, pemetaan jalan aman bagi perempuan sangat dibutuhkan sebagai upaya untuk menciptakan lingkungan publik yang lebih aman, nyaman, dan inklusif. Pemetaan ini membantu mengidentifikasi lokasi-lokasi yang dianggap rawan, minim penerangan, sepi, atau memiliki risiko terjadinya pelecehan dan tindak kekerasan. Dengan adanya pemetaan, pemerintah, komunitas, maupun masyarakat dapat mengetahui area yang memerlukan perhatian dan perbaikan. Selain fasilitas fisik, kesadaran masyarakat juga sangat penting. Lingkungan yang saling peduli, menghormati, dan berani membantu korban dapat meningkatkan rasa aman di ruang publik. Pemerintah, komunitas, dan masyarakat perlu bekerja sama untuk menciptakan lingkungan yang inklusif, aman, dan ramah bagi semua orang, terutama perempuan dan anak-anak sebagai kelompok yang lebih rentan terhadap risiko di tempat publik.

Nice routing algorithm you got, but have you considered I got a map, a vague sense of direction and impeccible luck.

Bin wieder Zuhause mit einer Totalwartezeit von 11 Minuten bei 4 mal umsteigen und bin mit meiner improvisieren Route mit Bus praktisch direkt vor meiner Haustür gelandet. Vielleicht wär mein weg noch schneller gewesen wenn ich statt StreetComplete und Bauchgefühl OSMand verwendet hätte aber guess I dont need to use the data, I just contribute to it…

Mein erstes mal OSM/FOSSGIS Stammtisch Berlin heute war super, bin ab sofort öfter dabei.

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.

Tools used: Python, OSRM (self-hosted), gpxpy

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

昨日、久しぶりにOSMのアカウントにLOGINした。 めちゃくちゃ前に残していたログがなつかった。

今つくってるアプリで、ささやかにOSMに貢献できるかも、と思ってる。

ボクは西暦2001年の夏に、豊橋市の小中高の学校や神社や駅などを自転車で回ってパノラマ写真を撮りまくったり、その後も消化器や諸々、GPSのPOI記録しながら狂ったように収集してた。意味あると信じて。結局、HDDが壊れてデータが消えてしまい、いまはもう。

早上，爸爸叫我去学习“正常”的编曲，而不是我自己瞎写的“不正常”编曲，但是我不想学，但我也不知道怎么样解除爸爸的期望，于是我拿起了旁边的剪刀，试图吸引注意，结果爸爸妈妈竟然以为我要杀他们，然后从此决定不再对我有什么感情，不再对我好，并表示可能会把我送进精神病院。 该段落于收集osm商铺poi的路上写下。 还有，蕉饼，你是如何找到我的网盘的？

Garmin Connect Integration​

You can now connect your Garmin Connect account in the Web Planner and automatically sync your activities with OsmAnd.

Once connected, activities are imported as tracks and stored in a dedicated Garmin Connect folder in the Tracks section. New activities are added automatically after they are recorded in your Garmin account. Imported activities are converted into tracks, and their types are preserved when possible. You can also sync recent activity history during the initial connection.

Read more about it in our blog article.

Smart Folders Support​

Smart Folders are now supported in the web version, allowing you to view and manage track collections created on mobile devices. Smart Folders are synced via OsmAnd Cloud when Settings synchronization is enabled.

On the web, Smart Folders are displayed in the track list with a distinct star icon for easy identification. The folder content depends on its configuration on the device, and only supported parameters are applied when displaying tracks.

Track Tools​

Several improvements were introduced to make working with tracks easier and more flexible.

Track Panel Redesign​

Redesigned track panel and context menu with a new top action bar, quick access controls, and tab-based navigation between Overview, Track, and Points.

Export GPX as Simplified Track​

A new export option allows downloading GPX tracks in a simplified format. This helps reduce file size and improves compatibility when sharing tracks with other applications or services.

Public Transport Stops​

Public transport stops can now be displayed directly on the map. Stop markers indicate locations where public transport routes operate. Selecting a stop opens a context panel with key information and quick actions.

The Routes section lists all routes serving the selected stop, including the transport type and route number. Selecting a route opens a detailed view showing the full sequence of stops, with the currently selected stop highlighted on the map.

POI Context Menu Improvements​

The POI context menu has been enhanced to display more useful information about locations directly on the map.

Opening Hours​

Opening hours are now shown directly in the POI context menu when this information is available. The menu also indicates whether a place is currently open or closed.

Wikimedia Metadata​

Photos from Wikimedia sources now display additional information in the POI photo gallery. When opening a photo, users can view details such as the date, author, license information, and a description of the image.

Pinned Favorite Folders​

Favorite folders can now be pinned so that frequently used folders appear at the top of the list for quicker access. Pinned folders are displayed in a separate section above the rest of the Favorites.

Favorites and Waypoint Editing​

The Favorites and waypoint editing workflow has been redesigned with a new unified Edit panel. Favorites and track waypoints can now be edited more conveniently, including name, address, description, folder, icon, color, and shape settings.

The updated interface also adds improved appearance preview both in the editor and on the map, categorized icon selection, custom color palettes, dedicated description editing, and easier folder management with support for creating new folders directly from the editor.

Selected Object​

When an object on the map (such as a POI, favorite, or navigation point) is selected, it is now highlighted with a distinct pin marker. Only one object can be selected at a time, and the map scrolls to it only if it is not currently visible on screen.

Bug fixes​

• Map jumped away from the selected track.
• Favorites were not displayed when opening folders.
• Scrolling issue in the track list.
• Favorite folders ending with .gpx could not be renamed.
• Incorrect statistics calculation for some multi-segment tracks.
• Slow route analysis when building complex routes.
• Crash when importing GPX files with longitude equal to 0.0.
• Shared track links required a page refresh to open correctly.
• Incorrect geocoding results for some addresses.
• Some Wikimedia photos were not displayed for POIs.

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 isn’t legal advice]

Lots of data is Switzerland is produced by the cantonal GIS offices (while it might seem to originate from swisstopo it often doesn’t), for example the hiking path/trail data is all cantonal and we can only utilise such data, even when using the data distributed by swisstopo, if the cantonal terms are compatible with our license.

In the following I’m using open in a hand wavy, “close enough” fashion here, and not applying the strict definition as per the open defintion. Class A refers to the federal ordinance definition for generally accessible geo data¹.

To set the scene: Switzerland does not have sui generis database rights regulation or anything similar, nor does it adhere to a sweat of the brow copyright doctrine. Between non-government entities any (minimal) protection available is based on contract and fair competition law. The big exception is geo data where the federal government has written in to law rights that are essentially a “data copyright light” and many of the cantons have followed suit.² There is no relevant case law that I know of and how any of this would work out in an actual dispute is, well, open.

The cantonal regulations are, being nice, quirky. For example Appenzell Ausserrohdens reference to federal copyright law that is going to put any lawyer that needs to determine if access is possible in to a tail spin. And while referencing GeoIV Art 30 (the federal ordinance) as Luzern does, would superficially seem to be good given that we have access to swisstopos data, it actually rules out use in OSM.³ Most of the No entries for otherwise “open” data are due to downstream attribution requirements. In some cases the “ToU” or similar are available in separate documents or are distributed with the data, obviously I can’t make any overall statement in such cases. I would further note that a No in the OSM compatible column isn’t absolute but it does imply high friction and potential negotiations on a dataset by dataset base, for example we imported addresses from the Canton Berne back in 2016 https://sosm.ch/building-addresses-canton-berne/.

NOTE this does not cover access to cadastre data (AV, Amtliche Vermessung) that typically has specific regulations, but naturally if “normal” class A data isn’t open the cadastre data isn’t going to be either.

? law or ordinance unclear or delegates to tou that are not included in the relevant law or ordinance

Updates: - 2026-05-15 BS removed any attribution requirement for class A in February 2026.

2. why these offices felt the need for these counterproductive rules is unclear, maybe it is a holdover from the old days when the main product was maps, which are naturally covered by classical creative work copyright. In any case it leads to absurd consequences for example the EMBAG https://www.fedlex.admin.ch/eli/cc/2023/682/de#art_10 having to make a specific exception to cater for this silliness and making the data unavailable for the largest open geo data project in the world. ↩

3. the swisstopo data is accessed based on a specific exception in their ToU that we had to fight for and which does not exist for the canton Lucerne, see https://sosm.ch/use-of-swisstopo-data-and-products-with-and-in-openstreetmap/. ↩

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.

Hello friends!
We are excited to announce a new feature that allows you to sync your activities from Garmin Connect™ with OsmAnd. This integration, now available for OsmAnd Pro users, enables you to automatically import your Garmin activities and view them in the Tracks section under a new folder called "Garmin Connect."

You can now easily access your Garmin activities within OsmAnd to use them for navigation, analysis, or sharing. This update makes it simpler to keep all your outdoor adventures in one place and seamlessy integrate your Garmin data with OsmAnd’s mapping tools.

How it works​

First, you need to sign in to OsmAnd web using an active OsmAnd Pro subscription. Then you will need to connect your Garmin Connect™ account with OsmAnd Web. Once connected, OsmAnd will automatically sync your activities from Garmin Connect™ and create a new folder called "Garmin Connect" in the Tracks section. All your synced activities will be stored in this folder, allowing you to easily access and manage them.

Connecting​

To connect your Garmin Connect™ account with OsmAnd Web, follow these steps:

Go to OsmAnd Web Map > OsmAnd Account > Connected Apps and click on the "Connect" button.

You will be redirected to the Garmin Connect™ login page. Enter your Garmin Connect™ credentials and authorize OsmAnd to access your Garmin Connect™ account. Here you can choose sharing of Historical data (see details below). Click to "Save" button for continuation.

Menu​

After successful authorization, you will see the Garmin Connect™ menu in your OsmAnd Web account with two section - "My data" and "Settings".
"My data" section contains "Synced activities" folder with all synced activities from Garmin Connect™, button "Last synced" activity, and Button "View on Garmin Connect™" that will redirect to your Garmin Connect™ account.
In "Settings" section you can choose type of activities to sync and the disconnecting button.

My Data​

• All your synced activities from Garmin Connect™ will be stored in the "Garmin Connect" folder in the Tracks section.

You can view, analyze, and manage your activities directly within OsmAnd Web. This integration allows you to have all your outdoor adventures in one place, making it easier to track your progress and share your experiences with friends.

The "Garmin Connect" tracks folder will be synced with OsmAnd mobile app, so you can also access your Garmin activities on the go. This means that you can view your Garmin activities on your mobile device and use them for navigation, analysis, or sharing with friends while you're out exploring.

• The "Last synced" activity button opens last synced activity from Garmin Connect™ in OsmAnd Web. This allows you to quickly access your most recent activity and view it in detail.

• The "View on Garmin Connect™" button will redirect you to your Garmin Connect™ account Activities page, where you can view your activities in more detail and access additional features provided by Garmin Connect™.
  Not all activities from Garmin Connect™ may be synced with OsmAnd Web. Currently, only activites types what you choose in "Settings" > "Activites to sync" section will be synced.

Settings​

Here you can choose which types of activities to sync with OsmAnd Web. Go to "Settings" > "Activities to sync" and select the activity types you want to sync.

After selecting the activity types, OsmAnd Web will automatically sync only those activities from your Garmin Connect™ account that match the selected types. This allows you to customize your syncing preferences and ensure that only relevant activities are imported into OsmAnd Web.

For disconnecting your Garmin Connect™ account from OsmAnd Web, go to "Settings" > "Disconnect" and click on the "Disconnect" button. This will revoke the access of OsmAnd Web to your Garmin Connect™ account and stop any further syncing of activities.
Your tracks from Garmin Connect™ will remain in the "Garmin Connect" folder in the Tracks section of your OsmAnd Web account, but no new activities will be synced until you reconnect your Garmin Connect™ account.

Sono entrato a far parte della community OSM da poco, e nell’ultimo mese ho iniziato a prendere sul serio l’attività, decidendo di impegnarmi per tenere aggiornato e arricchire il database. La domanda è: ci sono dei mappatori in provincia di Varese che sono disposti a scambiare opinioni e consigli?

海西州飛地一大塊全劃到西藏去了…怎麼沒人改呢…無語…

二編：已得知唐古拉山鎮南部均租借給西藏。

你好，陈欣恬，我是钱辰飞。很快就又到你的生日了，这一年来，你从未回我一句话。上次你生日，那个球可真好玩，可是我估计一辈子也不会再做出那个球了，因为我已经忘了怎么做了，这有点可惜。初二下对我是很有意义的，这是在小组死后我拥抱个人的降级选择，我和你发生了许多有趣的事情，这些事情历历在目，不可再来，但我也对你做了很多错事，例如硬要送你钱，即使你不要，或者乱说爱你，还有在11上把你弄摔倒。这些事情是个大问题，因为我竟然不考虑你的感受，这可能也是你离开的原因吧。我现在好抱歉，我一直对你做错事，让你在学期末时其实很讨厌我了，而且我在小组群里一直发乱七八糟的东西，偏离了小组的宗旨，让我被其他人也讨厌。桃源兴城苑我是不敢再进去了，我也不应该进去，虽然经常路过，但也就只能远远看看，我也不知道你到底还在不在里面，只是暗中相信你还在。那里真的挺美，地下天窗好好看，好有趣，你和我在那里向下看真实有趣又神经。未来还能不能见到你，我对这个问题的答案是偏向于否定的，我其实不觉得你会想要见到我，反而见到米豪的概率大一点，我可能会带米豪去浙江。 再见，来自小组：钱辰飞。

On the quiet early morning of 18 July 2018, pilgrims from the Mega Arafah Hajj Guidance Group (KBIH Mega Arafah) gathered at the Mega Arafah office near Gedung Sate.

Their first stop was West Java Regional Police headquarters (Mapolda Jabar Gedebage), where pilgrims from across Bandung had assembled.

Soon, ten buses departed together toward the Embarkasi Haji Bekasi, creating a convoy stretching along the highway out of the city.

The trip to Bekasi took around six hours. Along the way, the convoy stopped for lunch at a restaurant (RM Cibening Sari) in Purwakarta before continuing westward. By evening, the embarkation complex was bustling with pilgrims from West Java, Jakarta, Banten, and Lampung, all preparing for the same journey.

The next day began long before dawn.

At 2 a.m., pilgrims woke to prepare for departure to Soekarno–Hatta International Airport. By 4 a.m., buses rolled out from the embarkation center, and at 7 a.m. the pilgrims boarded their aircraft. At 8:15 a.m., the plane lifted into the sky, carrying pilgrims toward Saudi Arabia.

Around 2 p.m., the group landed in Medina. After immigration and airport procedures, buses brought them toward their hotel. Twenty minutes later, they arrived at Taiba Arac Suites, located near Gates 16 and 17 of Al-Masjid an-Nabawi.

During their stay, the pilgrims joined several city tours, visiting Quba Mosque (regarded as the first mosque in Islam) as well as Mount Uhud, the historic battlefield of the Battle of Uhud. They also visited date orchards on the southern outskirts of the city.

After eight days in Medina, the journey continued toward Mecca. On the afternoon of 17 July 2018 (16.30 pm), the buses departed the city. About thirty minutes into the journey, the pilgrims stopped at Dhul Hulayfah Miqat Mosque, commonly known as Bir Ali Mosque, to enter the state of ihram before continuing the six-hour trip southward across the Arabian desert.

As the buses approached Mecca, they passed through security checkpoints near the city boundary.

Around 1 a.m., the convoy finally arrived at their hotel in the Syisyah 2 district. The pilgrims rested only briefly before preparing for their first umrah. At around 2 a.m., they boarded free buses provided by the Indonesian government toward Masjid al-Haram. The ride from Syisyah 2 to the Syib Amir terminal took roughly twenty minutes.

From Syib Amir, the pilgrims entered through the Marwah side of the mosque complex and walked toward the Kaaba through the sa’i corridor.

Stepping into the mataf area, the pilgrims began their tawaf, starting from the Hajar al-Aswad. The tawaf took around an hour. After tawaf came the sa’i between Safa and Marwah. Their sa’i was briefly interrupted by the approaching Subuh, and they completed the sa’i around 6 a.m. The umrah concluded with tahallul, marking the end of the ihram state. The pilgrims returned to Syib Amir terminal and traveled back to their hotel in Syisyah 2.

The days that followed were filled with additional visits around Mecca. One stop was the Al-Kakiyah goat market, where pilgrims arranged their animals. They also visited Mount Arafat, Mina, and Jabal Nur.

As the days of Hajj approached, preparations intensified. The Saudi government announced that the wuquf in Arafah would take place on Monday, 20 August 2018. On the previous day (Sunday, 19 August 2018), Indonesian pilgrims began moving toward Arafah.

At around 1 p.m. on Sunday, the pilgrims gathered in the hotel lobby before boarding buses bound for Arafah. The journey took about forty-five minutes. Upon arrival, endless rows of white tents covered the plain beneath the rocky hill of Arafah.

On 20 August, the wuquf officially began after noon.

Later that afternoon, the pilgrims prepared to leave Arafah for Mina. Heavy traffic slowed the movement of buses, and they did not arrive at their Mina tents until around 10 p.m.

Near midnight, preparations began for the Jamarat Aqabah. The pilgrims walked roughly five kilometers from Mina toward the Jamarat Bridge complex. After completing the Jamarat, they walked all the way back to Mina, arriving around Subuh time the next morning. With the completion of Jamarat Aqabah and tahallul, the state of ihram came to an end.

As the days of Tashriq continued, the rhythm of the pilgrimage became increasingly demanding. Around midnight, the pilgrims once again walked toward Jamarat, arriving around 2 a.m. to perform the Jumrah Ula, Wustha, and Aqabah. Afterward, instead of returning to Mina, they continued on foot directly to their hotel in Syisyah 2, reaching it around 4 a.m. after walking approximately three kilometers.

The following day, they returned once more to Jamarat, this time walking through the Mina tunnel system (King Fahd Road Tunnel). Although they arrived around sunset, the actual Jamarat was performed later at around 2 a.m.

With the completion of the second day of Tashriq, the group chose nafar awal and departed Mina earlier.

From Jamarat, they walked all the way to Masjid al-Haram.

By the time they arrived, the Subuh was approaching. After performing Subuh, the pilgrims completed the tawaf ifadah followed by sa’i.

At that moment, their Hajj pilgrimage was finally complete.

Since the free bus services were not yet operating at that hour, the pilgrims returned to Syisyah 2 by taxi.

Two days before departure from Saudi Arabia, the pilgrims returned once more to Masjid al-Haram to perform the tawaf wada, the farewell tawaf. This final tawaf took place around Subuh time. By then, the free Indonesian bus services had resumed, making the journey to the Grand Mosque easier.

One day before departure, suitcases filled the hotel lobby as baggage was collected for airport transport. The following morning, shortly after Subuh, the pilgrims boarded buses leaving Mecca for Jeddah. The drive to the airport took around two hours.

At 2 p.m., 29 August 2018, they boarded their flight at King Abdulaziz International Airport.

After nine hours in the air, the plane landed back at Soekarno–Hatta Airport around 3 a.m. the next day.

From there, buses carried the pilgrims back to the Bekasi embarkation center, before the final journey home to Bandung.

Я створив невеликий втулок для JOSM з назвою Fillet Tools (fillettools.jar).

Він додає інтерактивний режим для заокруглення кутів ліній, подібний до інструмента «fillet» у CAD-програмах. Основний сценарій використання — контури підʼїзних шляхів та інша точна геометрія, де ручне розміщення кількох точок для заокруглення кута займає багато часу.

Ви можете знайти проєкт у репозиторії GitLab, а завантажити перший тестовий jar-файл — зі сторінки релізу v0.1.0.

Як це працює:

• увімкніть режим Fillet Tools на панелі інструментів (або натисніть клавішу V);
• наведіть мишу на лінію або всередину замкнутого багатокутника;
• біля доступних кутів зʼявляться маленькі маркери (ручки);
• потягніть за маркер, щоб побачити і підібрати радіус бажаної дуги;
• відпустіть кнопку миші, щоб застосувати заокруглення.

Також є дві корисні клавіші-модифікатори:

• Shift привʼязує радіус до фіксованого кроку, що полегшує створення кількох кутів з однаковим радіусом;
• Alt / Option дозволяє «надмірне» перетягування для створення більших дуг. Втулок усе одно перевіряє фінальну геометрію перед застосуванням змін.

Я намагався зробити так, щоб втулок дбайливо ставився до даних. Він використовує стандартний стек команд JOSM, тому скасування дій працює належним чином. Він також намагається не замінювати і не видаляти важливі вже наявні точки. Початкова кутова точка разом із історією залишається на новій дузі.

Важлива примітка: я абсолютний новачок у програмуванні й використовував ШІ-агента для написання цього втулка. Тож у коді можуть траплятися дивні, неефективні або просто помилкові речі. Будь ласка, майте це на увазі, якщо переглядатимете репозиторій або тестуватимете втулок.

Наразі втулок недоступний у загальному списку JOSM. Щоб протестувати його, вам потрібно завантажити fillettools.jar зі сторінки релізу, вручну покласти його до теки втулків JOSM і перезапустити редактор.

У багатьох дистрибутивах Linux це: ~/.local/share/JOSM/plugins/

На macOS це зазвичай: ~/Library/JOSM/plugins/

На Windows це: %APPDATA%/JOSM/plugins/

Буду радий, якщо хтось протестує його на практиці. Відгуки, звіти про помилки, випадки з дивною поведінкою та пропозиції можна писати тут у коментарях або на GitLab.

I made a small JOSM plugin called Fillet Tools (FilletTools.jar).

It adds an interactive mode for rounding corners of ways, similar to a fillet tool in CAD software. The motivation is simple: in the real-world, many objects are not designed with sharp corners. Roads, sidewalks, residential landuse areas, sports fields, running tracks, and other planned infrastructure often have smooth, consistent curves. Mapping these curves by hand usually means placing several nodes one by one, which is slow and often inconsistent. Fillet Tools is an attempt to make this specific editing task easier in JOSM.

You can find the project in the GitLab repository, and download the test JAR from the v0.1.2 release.

How it works:

• enable the Fillet Tools mode from the toolbar or by pressing v;
• move the mouse over a way or inside a closed polygon;
• small handles appear near available corners;
• drag a handle to preview the radius;
• release the mouse button to apply the rounded corner.

There are also two useful modifier keys:

• Shift snaps the radius to a fixed step, so it is easier to make several corners with the same radius;
• Alt / Option allows a larger “oversize” drag for bigger arcs. The plugin still checks the final geometry before applying the change.

I tried to make the plugin careful with data. It uses the normal JOSM command stack, so undo works as expected. It also tries not to replace important existing nodes. In the usual case, the original corner node is moved onto the new arc instead of being deleted, so its local/OSM id history is preserved as much as possible.

Important note: I am an absolute beginner in programming, and I used an AI coding agent to help write this plugin. So there may be strange, inefficient, or simply wrong things in the code. Please keep this in mind if you look at the repository or test the plugin.

For now the plugin is not available from the JOSM plugin list. To test it, you need to download FilletTools.jar from the release page and copy it manually into your JOSM plugins directory.

After copying the file, open Preferences → Plugins in JOSM, search for Fillet Tools, and enable the checkbox next to it. Then restart JOSM. After restart, the plugin should be ready for testing.

Typical plugin directories are:

On Linux:

~/.local/share/JOSM/plugins/

On macOS:

~/Library/JOSM/plugins/

On Windows:

%APPDATA%/JOSM/plugins/

I would be happy if someone could test it on real mapping tasks.

Feedback, bug reports, strange geometry cases, and suggestions are very welcome. You can write them here in the comments, or on GitLab.

Quienes se interesan en la región de América Latina saben que somos relativamente jóvenes en la organización de los States of the Map regionales, iniciados en 2015 después de un encuentro fortuito entre personas apasionadas por OpenStreetMap de diferentes partes de la región durante la conferencia Abrelatam en la Cineteca Nacional de la Ciudad de México en 2014 (mismo contexto en el que se decidió crear un chat de Telegram regional, semilla de la comunidad actual). Posterior a este año, se tuvo cierta continuidad hasta la pandemia, por obvias razones, y también por una desmotivación generalizada de la comunidad, que había vivido cierto “renuevo generacional” que había tenido poca interacción con las pasadas, y, claro, también por la precarización general causada por la pandemia, de la que no nos hemos repuesto ante la situación global actual.

Retomaron después de 5 años las conferencias en Belén, Brasil, en 2024, desde una agrupación de personas entusiastas, relativamente continuas con la organización del evento siguiente en Medellín en 2025 y con relativa continuidad también con este próximo evento de 2026 en Ciudad de México.

Hoy estamos a medio proceso de esta gestión y muy emocionadxs. Si algo caracteriza a México es el orgullo y felicidad por compartir lo suyo. Felices de unir a muchas personas de LATAM y de otros lados, estamos en pleno periodo de convocatoria abierta

para charlas y talleres, en torno a tres ejes: el eje general; un eje académico (estudios con más rigor y con proyecto de publicación colectivo en revista científica); y un eje institucional. ¡¡Anímate a participar, desde cualquier parte del mundo!! -> https://www.facebook.com/share/p/18bRwJ5Xr4/ -> https://www.instagram.com/p/DXYCczJl7fu/?img_index=1 -> https://www.osmlatam.org/sotm/2026-es/

Compártenos experiencias, reflexiones, casos de uso, propuestas comunitarias, posturas sobre la comunidad OSM Latam, talleres técnicos básicos y avanzados, tecnologías, etc. Una visión propia de esta edición, es un deseo grande de institucionalizar el uso de OSM en organizaciones públicas y la toma de decisiones que afectan los territorios.

Esta edición tiene también un fuerte liderazgo femenino y joven, con la participación siempre más central de las participantes de Geochicas, y un comité de diversidad e inclusión, y la participación desde el comité organizador de la generación comunitaria de los recientes años. El evento sucederá junto a los 10 años de Geochicas, un seminario en los días posteriores.
