What is a .OSM file?
OSM is the XML data format of OpenStreetMap, the crowd-sourced world map.
- Did you know
- OpenStreetMap, started in 2004, is built by volunteers mapping the whole world.
- OpenStreetMap was started by Steve Coast after the UK’s Ordnance Survey declined to release its mapping data under a free licence.
- Map data is published under the Open Database Licence, and the entire planet is offered as either this XML or the more compact binary PBF form.
- What Analyser reads
- Inspect geospatial and GIS files without a map: TopoJSON, OpenStreetMap XML, Esri Shapefile siblings (SHP/SHX/DBF/PRJ/CPG), world files, GML, NMEA GPS logs, IGC flight logs, MapInfo TAB/MIF, GDAL VRT, PMTiles, DTED terrain, Esri ASCII grids and SRTM .hgt - surfacing CRS/EPSG, feature/record counts, bounding boxes and elevation ranges. GRIB/NetCDF/GeoPackage/MBTiles/MrSID/ECW identified.
- Depth of analysis
- .OSM is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .OSM file
- Drag a .OSM file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
