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.

About Geography Markup Language (GML)

The OGC XML standard used by government cadastres and INSPIRE datasets across Europe.

Worth knowing: Schema-heavy; application schemas may need the companion .xsd.

How the conversion works

Drop your GPX 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 GML result, with a transformation report showing exactly what was done.
