[Francophone] [veille] nouveau MNT "ouvert"

[François Van Der Biest]

Voici une première étude rapide (à ma connaissance) sur la qualité des
données ASTER:

par Markus Neteler.

Conclusion: "Despite spikes (including unexpected craters), the
overall quality appears to be acceptable for this first version of
ASTER GDEM - the standard deviation is 18m for the test area with
outliers predominantely found in the areas of complex terrain rather
than in the valley floors. A shift of -2.3m is also observed
(reprojection artifact?)."
