Mapping

CloCkWeRX asked about making it easier to import and assess data. He suggested using standard metadata and tools to improve data quality and reliability. The goal is to automate tasks while still checking for mistakes to maintain high standards and save time.
In Geoawesome, Sebastian Walczak and Nikita Marwaha-Kraetzig discussed the use of GPS tracks to turn digital footprints into urban intelligence. By analysing anonymised GPS data, platforms such as OpenStreetMap and Strava can contribute to improving urban planning, traffic management, and public health initiatives.
Gregory Peony shared a tip on how to provide efficient feedback to contributors in Tasking Manager projects as a validator.
Quinn Comendant tooted the usefulness of editing OpenStreetMap. He had marked Nortz Road as private because it goes through a military base. Several mapping tools have been updated within 21 days to now avoid the road.
StreetComplete How-To explained in a video how to enhance OpenStreetMap by adding data using the ‘Things’ overlay feature in the StreetComplete app.
Comments are requested on:
- The proposal to deprecate the tag cycleway=shared in favour of more precise tags.
- The proposal to recognise the cycleway:both=* tag as the new standard to indicate both sides.
- The proposal to replace the tag denomination=mormon with denomination=latter-day_saint.
The vote on the proposal to specify ordering-only phone numbers, SMS-only phone numbers, and related tags has concluded with 10 votes in favour, 0 against, and 5 abstentions.

Mapping campaigns

OpenStreetMap Utah is using Mapillary images to improve the OpenStreetMap data in Utah. Martijn van Exel talked about the current coverage in Salt Lake City, the gaps in recent images, and how people can contribute by taking and uploading images using the Mapillary app. OSM Utah offers tools like a GoPro MAX camera and hosts events to facilitate participation in this project.

Community

OpenHistoricalMap celebrated its 15th birthday with a retrospective and a terrible pun.

TBesse, a newcomer to the community and obvious expert on boundary stones in real life, has quickly familiarised himself with the mapping of these small historical monuments in OpenStreetMap. Apparently, Lutz Lange from gk.historic.place had a hand in providing good tips. TBesse described in his blog posts 1 ►, 2 ► and 3 > , and also documented the data with his own publications. Tobias Jordans has provided a suitable overpass query for this mapping in his comment.
UN Mappers marked the 20th anniversary of OpenStreetMap by celebrating its role in promoting open geographic data, improving global mapping, and fostering community collaboration.

It includes roughly seven hours of training material with real-world workflows and case studies in QGIS, uMap, Disaster Ninja, and Openrouteservice. The course is free and is targeted at communities, organisations, and individuals interested in using OSM more in their work. A certificate of completion is awarded.

Maps

[1] The list of venues for the 2024 Summer Olympics in Paris is now available on the OpenStreetMap wiki. This list is also available as an interactive uMap map. A nice example of what OSM can do: OpenStreetMap vs market benchmark.
Andrii Holovin, aka andygol, recently shared ►, on LinkedIn, a quick experiment with OpenStreetMap data. Using Tilemaker, OpenMapTiles styles, the Maputnik editor for styling, MapLibre GL JS for rendering, and a local tileserver-gl, he created a simple map style featuring roads and place names. He challenged viewers to see if they could identify cities from just the road network shapes without labels.

This app provides a comprehensive analysis of population distribution and public service coverage in six priority Asia-Pacific countries: Vietnam, Laos, Myanmar, Nepal, Afghanistan, and Pakistan.
Tatvic Analytics compared MapMyIndia, Google Maps, and OpenStreetMap. It found that the best choice depends on your specific business needs. MapMyIndia is considered best for detailed local data in India, Google Maps for global reach and comprehensive features, and OpenStreetMap for open-source flexibility and budget constraints.
An article on CSDN provides a guide on downloading and using OpenStreetMap road data. The article explained the benefits of OSM and offered instructions on obtaining data from the OSM website and Geofabrik. The guide also covers using OSM data in GIS software like ArcGIS.

OSM in action

Using OpenStreetMap data, the emergency section of the app shows the geolocation of the nearest police stations, Women’s Emergency Centre offices, and other resources. With more than 11,000 downloads, it has established itself as an important support tool for women in situations of violence.

Software

In OSMfocus Reborn 1.6 you can now view OSM nodes, ways and relations separately. The application has also become more stable when working with a poor internet connection.

The guide also shows you how to add and display map markers.
Prabinoid described moving Tasking Manager from Flask to FastAPI and from psycopg2 to asyncpg. This aimed to improve performance and scalability by using asynchronous programming, modern Python features and optimised database interactions. Despite challenges like learning the new system and changing code, he stated in a community discussion that the move offers benefits including better throughput and simpler API development.
Milan Janosov showed how to use Python libraries to create isochrones, which show areas accessible within a specific time frame from a starting point. The post guides you through setting up the environment, obtaining OpenStreetMap data, building a graph of the road network, and calculating isochrones.
