OSM research

The United States Census Bureau has developed a socioeconomic profile of the commuters affected by the collapse of the Francis Scott Key Bridge, in Baltimore, based on OSM data and OSRM.

Maps

Daniel J. H. explored in detail the evolution and mechanics of OpenStreetMap’s vector tiles, highlighting their advantages over raster maps, detailing the Mapbox vector tile specification, and discussing challenges such as data redundancy across tiles.

Specifically, the polygons of flood areas were generalised from data from the National Institute for Space Research, which is also available from the ‘Flooding in Brazil’ activation on Disaster Charter. This initiative was blogged ► in Dr Raquel Dezidério Souto’s diary.

OSM in action

Releases

Garmin has released a new CycleMap and TopoActive map update, version 2024.10, for compatible wearable and handheld GPS devices. It improves navigation with updated map data while maintaining the same memory footprint. In case you didn’t know, these maps are based on OpenStreetMap data.
Bryan Housel announced the release of Rapid v2.3 for OpenStreetMap, introducing features such as Esri Wayback imagery for historical views, map rotation, MapRoulette integration for task management, and GeoScribbles for field notes.

OSM in the media
