What is a .GeoJSON file?
GeoJSON is a JSON format for geographic features such as points, lines and polygons.
- Did you know
- GeoJSON was published in 2008 and standardised as RFC 7946 in 2016.
- GeoJSON deliberately lists coordinates as longitude before latitude, the reverse of how people usually say a location aloud, which trips up many newcomers.
- The RFC 7946 standard fixed all GeoJSON coordinates to the WGS 84 datum used by GPS, dropping the alternative coordinate systems the original draft had allowed.
- The format mandates a right-hand rule for polygon winding order, so the way you list a ring’s points encodes which side is the interior.
- A .GeoJSON file is plain text, so you can open and edit it in any text editor.
- What Analyser shows you
- Parse GPX tracks, KML placemarks, and GeoJSON features - counts, distance, elevation, time span, and bounds - plotted on an OpenStreetMap map.
- Open a .GeoJSON file
- Drag a .GeoJSON file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
