What is a .GML file?
GML is an XML standard for describing geographic features. Defined by the Open Geospatial Consortium. The same extension is also the GameMaker Language script and the Graph Modelling Language.
- Did you know
- GML is the OGC’s XML grammar for sharing maps and spatial data.
- GML was also adopted by ISO as standard 19136, the result of collaboration between the Open Geospatial Consortium and ISO’s geographic-information committee.
- GML can describe not just points and lines but coverages, coordinate reference systems and rich geographic feature models.
- 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
- .GML 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 .GML file
- Drag a .GML 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.
