Hintereisferner (Alps)

Located in the Austrian Alps (46°47‘43”N 10°46‘01”E), RGI60-11.00897.

The sources available are: ASTER, COPDEM, AW3D30, DEM3, MAPZEN, NASADEM, SRTM and TanDEM-X.

Summary

  • in an easy location in the mid-latitudes, all DEMs are qualitatively OK
  • DEM3 is the most different from all, with an obvious higher elevation tongue
  • worrying generalised bias between SRTM and TanDEM-X, the latter being higher of 40m in average
  • ASTER and SRTM agree the most
  • NASADEM shows noticeable differences to SRTM in steeper (often unglaciated areas) which are also present in e.g. AW3D30. But the flatter parts of the glacier are very similar.
