Community

TomTom’s video celebrated OpenStreetMap’s 20th anniversary, highlighting its journey from a community-driven project, founded by Steve Coast in 2004, to one of the world’s most detailed maps. Steve Coast reflected on OSM’s evolution, its global impact on democratising mapping, and its role in empowering millions daily through open collaboration, as the video invites viewers to envision the future of mapping.
As the year comes to an end, OpenStreetMap Utah community has spotlighted some of their key achievements of 2024.

Imports

IVIDES.org has updated / their correspondence table between the CNEFE 2022 variables (The Brazilian National Address Register for Statistical Purposes) and the OSM labels for mapping educational POIs. This phase is part of the effort to import ► the CNEFE 2022 data, which is the result of the 2022 Brazilian Demographic Census and had its revised version released in 2024.

OpenStreetMap Foundation

OpenStreetMap has been selected as one of the 10 beneficiaries of Proton’s 2024 Lifetime Account Charity Fundraiser.
The OpenStreetMap Foundation has been awarded a 384,000 EUR service agreement by the Sovereign Tech Fund, supporting the modernisation of OpenStreetMap’s core software over the next two years. The funding will enhance code standards, improve documentation, and create new roles, including a Core Software Development Facilitator, to strengthen the platform’s infrastructure and community contributions.

Events

SotM Latam 2024 was held from 6 to 8 December and many of the participants have shared their views on the event.

OSM research

Researchers have developed the GURS dataset (Global Urban and Rural Settlements) at a 100 m resolution for 2000–2020, using OpenStreetMap data to classify urban and rural settlements worldwide. OSM’s ‘place’ feature provided essential labels for identifying settlement types, showcasing its critical role in creating accurate dynamic maps for global urban-rural studies.
Raquel Dezidério has blogged /, in her diary, about two studies presented at the VII Geotechnologies’ Journey of the State of Rio de Janeiro, which used collaborative data from OpenStreetMap in researching high density urban areas in the City of Rio de Janeiro (Brazil). One of the studies was aimed at identifying public areas and the other at classifying images to detect smaller targets, such as rooftops and water tanks. Both extended abstracts can be accessed in the e-book of the event.

Maps

Hywelm has built [CY] an OpenStreetMap-based interactive [CY]► map that shows the percentage of households with dependent children where all adults can speak Welsh, based on the 2021 Census data.
Eugene Alvin Villar has created the classic 15-puzzle game featuring standard OpenStreetMap tiles as the sliding pieces. You can choose from 20 different map locations to play.

OSM in action

Simon Poole noted that Niantic funds the Linux Foundation’s Overture Maps initiative but has not directly supported OpenStreetMap. Nevertheless the story about Pokémon Go helping a stranded group after Google Maps failed them is positive press for OSM.

Open Data

Amanda McCann revealed that WaterwayMap now includes a first attempt at data export. This is updated daily and compressed into a 6.5 GB CSV file. The data is extremely detailed, but difficult to work with in some GIS software; feedback on preferred formats is welcome.

Software

Organic Maps has celebrated its 4th anniversary, reflecting on its growth to nearly 3 million users globally, while remaining a privacy-focused, open-source alternative to proprietary map services. Launched during Christmas 2020 as a response to the decline of MAPS.ME, Organic Maps continues to thrive with no marketing spend, relying solely on community contributions and organic growth.
The community is questioning whether the SCEE StreetComplete fork has been discontinued, as development has slowed significantly due to the lead maintainer’s limited availability, prompting discussions about its future and potential contributions from others.
The Prototype Fund has funded OSM2World in its 16th round, supporting a roadmap focused on integrating 3D model generation into applications, introducing features including 3D tile generation in glTF and Cesium.js-compatible formats, customisable assets, modular architecture, and enhanced map styling. These improvements aim to simplify the tool’s use for developers and encourage its integration across diverse platforms.
The yearly wrap-up of GNOME Maps highlighted significant advancements made in 2024, including client-side vector tile rendering with features like dark mode support, clickable POI icons, and localised labels. Other updates include UI improvements using modern libadwaita widgets, an enhanced OSM POI editing dialogue, and integration of public transit routing through Transitous with future updates expected for improved performance.
Andreas Gruber is developing touring.studio, an iOS travel guide app powered by OpenStreetMap data.

Programming

^[1] Pascal Neis first conducted a study that identified regions (locations) in Germany that still had potential for more detailed OSM mapping in 2010. In 2016 Pascal extended the analysis to the whole world. He has recalculated the analysis as at 7 December 2024 and published the results on his website: ‘Unmapped Places of OpenStreetMap‘.
Dmytro Lapko, a 17-year-old programmer from Kyiv, Ukraine, has developed a model of an autonomous navigation system for UAVs that uses OpenStreetMap data and laser rangefinders to map and navigate urban environments without relying on GNSS or internet connectivity, making it resistant to electronic warfare.
SB-AI-Lab has developed ► RIDE, a Python library designed to perform shortest path calculations. The library includes built-in functionality for calculating routes directly from OSM data.

Releases

Bryan Housel announced the release of Rapid v2.5, which comes with a boost in performance thanks to the upgrade of its rendering engine, Pixi, to version 8. This version also introduced a new kerb validator and added two new datasets: Overture places, containing over 50 million POIs, and Open Map Data footways, currently only available in 5 US cities.
GeoTools 31.5 has introduced improvements including simplified feature collection handling, enhanced styling APIs, and extended support for raster data formats, providing developers with a more efficient tool for geospatial data management in Java-based applications.
Kelsey Taylor shared the new release of Stamen Location Service, which shows land cover at zoom level 1. You can find it on AWS.

OSM in the media

GeoGuessr user rainbolt showed how he uses Overpass queries to help him find the location used for an album cover photograph.
wwwhatsnew.com highlighted ► WaterwayMap for its visually striking and interactive design, which uses OpenStreetMap data to represent rivers with widths based on tributary contributions, colour-coded systems for clarity, and tools to explore watershed and water flow dynamics, offering valuable insights for education and environmental awareness.
EditorDavid has published a summary, on Slashdot, detailing the recent extended outage of OpenStreetMap.

Other “geo” things

UNICEF’s Frontier Data Lab, in partnership with Thinking Machines, has developed Geowrangler, an open-source tool that simplifies geospatial data preparation by automating tasks like feature extraction from OpenStreetMap and satellite data. This innovation has enabled applications such as mapping internet connectivity for schools, estimating vaccination coverage, and improving air quality monitoring, significantly enhancing the efficiency of humanitarian projects.
NASA highlighted the use of Global Navigation Satellite System (GNSS) data for tsunami detection, employing ionospheric ionisation waves caused by undersea earthquakes. This innovative method utilises GNSS signals to monitor atmospheric disturbances, offering a promising early warning system for coastal populations.
