Community

[1] Calvin Menttor blogged, in his OSM user diary, about his participation in the State of the Map Nigeria 2024. Kingsley Amankwe also published about his experience in the event and both were very pleased with the opportunity to participate.
Alexey Zakharenkov discussed an algorithm designed to detect missing stations on public transport routes in OpenStreetMap, overcoming problems such as accidental station deletions by comparing pairs of route variant ‘twins’ for discrepancies using the Wagner-Fischer algorithm, which detects mismatches similar to text-editing errors.
jjKlaus asked, on the OSM Community forum, how to handle the ongoing border disputes between Guyana and Suriname and between French Guiana and Suriname in South America.
SColchester shared insights from the 10th annual Missing Maps meeting in Nairobi, Kenya, where members discussed the project’s growth, challenges with their website, strategies for using OpenStreetMap data in humanitarian work, and plans to relaunch a data quality internship to promote community engagement and skill-building.
Some Amateur described the use of OpenStreetMap data during a firefighting operation, highlighting the critical role that detailed land-use mapping (such as ponds and wetlands) plays in real-world navigation, especially for emergency responders and outdoor enthusiasts who rely on offline, terrain-based guidance.
Christopher Beddow explored the evolution, cultural significance, and changing nature of place names (toponyms) throughout history, from colonial renaming and local vernacular names to digital innovations that may erase or preserve traditional toponyms. He highlighted examples such as Aotearoa in New Zealand, Romansh names in Switzerland, and the mixing of indigenous and colonial names in North America, noting how past naming conventions reflect local culture and geography.

Campus du libre will be held ► at the Université Jean Moulin Lyon 3, campus de la Manufacture des Tabacs (Campus of the Tobacco Factory), on Saturday 23 November.
The OSM Kerala Community Meetup 2024 is now the State of the Map Kerala 2024, the first regional OpenStreetMap conference to be held in India. The event will be on 16–17 November in Wayanad, Kerala and will focus on open mapping for disaster resilience, GIS, and humanitarian needs. Sponsored by partners including Meta and FOSS United, the event invites mapping enthusiasts to participate in talks, workshops, and networking activities. The sessions will be covering disaster preparedness, community resilience, and open data initiatives, among other topics.
State of the Map’s official Mastodon account tooted on several upcoming local, regional, and national State of the Map conferences, as well as other map-related events around the world. They suggested that event organisers who are planning a local State of the Map event apply for a SotM Quick Licence from the OpenStreetMap Foundation.

OSM research

Students at Malmö University (Sweden) have investigated the effectiveness of using OpenStreetMap data versus traditional cadastral data for predicting public violent crime in three Swedish cities of different sizes and found that while cadastral data generally produces more accurate predictions in smaller cities, OSM data produces comparable results in larger cities, suggesting the potential utility of OSM for spatial crime analysis.

Humanitarian OSM

The Spanish OpenStreetMap community has organised ► a mapping response to the tragic flooding that occurred on 29 October in the Valencia Province.
The Indonesian OpenStreetMap community has organised a mapping response to the Mount Lewotobi Laki-Laki eruption in East Flores, East Nusa Tenggara, Indonesia, which occurred ► early on Monday 4 November at 02:48 local time, resulting in at least nine fatalities. Many victims were killed ► by large rocks from the eruption that broke through house roofs. The eruption also triggered ► intense fires in homes and a school building, causing extensive damage.

Maps

Christoph Hormann discussed updates to his AC Style map symbols, including redesigned waste and recycling symbols, new symbols for towers, masts, cranes, benches, and oil wells, with an emphasis on readability, functionality, and cultural relevance for global map users.

OSM in action

The Louvre is using ► an OpenStreetMap-based map on its website to visually display the locations of its loaned artworks around France and internationally, improving public access to its collection through geographic mapping and cultural outreach.
Altilunium has developed Cmaxz, an OpenStreetMap-based weather radar map viewer.
PickYourPlace announced the launch of its real estate platform designed to provide comprehensive neighbourhood insights, such as safety, property values and accessibility data, to help users make informed housing decisions, initially focusing on Calgary, Canada, with plans for expansion.
OldMapsOnline is offering ► a vast, interactive archive of over 500,000 historical maps, allowing users to overlay these maps with modern OpenStreetMap data for comparison. The platform features a timeline slider to explore specific time periods and is valuable for historians, genealogists, and urban planners interested in studying geographic change and urban development over time.
Sylvain Machefert tooted that the Bordeaux-Nantes Intercités trains use dynamic displays with an OpenStreetMap-based map and Wikimedia Commons photos, although he noted the lack of Creative Commons licence attribution for the images.

Open Data

OpenSuperMaps has extended its data coverage to New Zealand, allowing users to download enhanced map files with detailed address and geographic data for use in mapping applications such as OsmAnd.

Licenses

KevinOs reflected on his effort to align local open data licences with Canada’s Open Government License, by comparing regional variations, noting minor differences in wording and attribution requirements tailored to specific legal frameworks. He highlighted inconsistencies in documentation across Alberta cities and advocated for clearer attribution guidelines and wiki updates by OpenStreetMap’s legal working group to ensure compliance and transparency.

Software

The Prototype Fund, a key resource for supporting OpenStreetMap and other open source projects, confirmed ► its continuation until at least 2029, with one funding round per year. New updates include increased team funding of up to GBP 78,800 (USD 102,000), eligibility for EU-based team members, and a shift in funding priorities to support data security and software components projects and less on civic tech.
Jaller94’s tool provides downloadable GPX files that identify missing Stolpersteine (Holocaust memorial stones, we have covered previously) in the neighbourhoods of Berlin, Germany, and allows users to upload these files to OpenStreetMap applications such as OsmAnd to complete local data for memorial locations.
