GeoJSON vs GPX: Web Mapping vs GPS Tracks
GeoJSON is a general-purpose geospatial format for web maps and APIs, supporting any geometry type with arbitrary attributes. GPX is a specialized XML format for GPS data — optimized for tracks, waypoints, and routes with native timestamp and elevation support.
Bottom line
Use GeoJSON for web mapping and general GIS. Use GPX for GPS device data where native timestamp and elevation semantics are important.
GeoJSON vs GPX: feature comparison
| Feature | GeoJSON | GPX |
|---|---|---|
| Geometry types | Points, lines, polygons, multi-* | Waypoints, tracks, routes |
| Timestamp support | Via properties | Native per track point |
| Elevation support | Via properties | Native (3D) |
| GPS device support | No | Yes (Garmin, Wahoo, etc.) |
| Polygon support | Yes | No |
| CRS | WGS 84 | WGS 84 |
GeoJSONWhen to use GeoJSON
- Web mapping with Leaflet, Mapbox, or MapLibre
- Datasets with polygon or complex geometry
- APIs and data exchange needing rich attributes
GPXWhen to use GPX
- Exporting GPS tracks from a device or app
- Hiking, cycling, or navigation data
- Any workflow needing native track/waypoint semantics

Frequently asked questions
Q.Can I convert GPX to GeoJSON online?
Yes. Maparz converts GPX to GeoJSON — track segments become LineString features and waypoints become Point features.
Q.Does GeoJSON support elevation data?
Yes — GeoJSON coordinates can include a third Z value for elevation. However, most web mapping libraries ignore the Z value for rendering.
