Inspect GPX
GPX 1.0/1.1 UTF-8 with matching Topografix namespace, version and creator. Tracks keep segment boundaries; routes and waypoints are separate. Distances use a mean-Earth-radius (6,371,008.8 m) spherical great-circle model and ignore altitude. Elevation totals use adjacent measured heights, never bridge missing heights or invalid points. Reject bad coordinates or explicitly keep gaps. Extensions are omitted; this is an inspection profile, not XSD certification. Coordinates/heights must round-trip as finite JSON numbers with safe integers; precision changes are rejected (invalid GPX heights are diagnosed and omitted).
