Retrieve the altitude of a point from Terrain Base 5', GTOPO30" and SRTM

This Web service, provided by MINES ParisTech, returns the altitude value in meters from three different Digital Elevation Models:

  • SRTM: spatial coverage in degrees: [-56S;+60N] [-180W;+180E], spatial resolution 90 m, uncertainty 10 m.
  • GTOPO30": worldwide, 30" d'arc = 1 km.
  • TB5': worldwide, 5' d'arc = 10 km.
