GPX vs GML: GPS Tracks vs OGC XML
GPX is a specialized GPS data format with native track, waypoint, and timestamp semantics. GML is the OGC's general-purpose XML geospatial standard for WFS services and government data exchange. They are rarely compared directly but you may encounter both in geospatial workflows.

Bottom line
Use GPX for GPS device data. Use GML for OGC WFS services and government standards-compliant data exchange.

Frequently asked questions
Q.Can I convert GPX to GML online?
Yes. Maparz converts GPX to GML — tracks become LineString features and waypoints become Point features in the GML output.
