About TopoJSON (TopoJSON)
GeoJSON's topology-preserving sibling — shared boundaries stored once, much smaller files.
Worth knowing: Read-only here: we convert from TopoJSON, not to it.
About GPS Exchange Format (GPX)
The universal GPS format for waypoints, tracks and routes. Always WGS84.
Worth knowing: Only points and lines (no polygons); fixed schema — arbitrary attributes go to extensions.
How the conversion works
- Drop your TopoJSON file above.
- We read it locally with GDAL compiled to WebAssembly — nothing is uploaded.
- Optionally pick an output coordinate system; official datum grids are applied automatically.
- Download your GPX result, with a transformation report showing exactly what was done.
