5 HRS August 2004 stereo image pairs: along-
track stereoscopic images (pixel size of 5 m along track
and 10 m across track) with ±20° forward and backward
viewing angles. From an automatic processing method
developed at IGN, using no check against ground truth
(e.g. Bouillon and others, 2006).
SPOT 5 HRS October 2004 stereo image pairs:
processed with PCI-Geomatica, using as ground truth

Geomatica software (PCI Geomatics; Toutin 2006),
constrained with a wealth of GPS GCPs in non-glaciated
areas. The resulting DEM was further corrected and
evaluated using all available profile and point observa-
tions both on and away from the glaciers (Fig. 2a,c).
