This paper presents the beginning of a three year pro ject which
regroups four laboratories to develop and combine specific
methods to extract information from optical and radar re-
mote sensing data. Preliminary results are presented on
three different information sources: airborne photography,
space-borne multi-spectral images and SAR interferome-
try, which respectively allow the compution of high reso-
lution DTM, the detection of glacial lakes and the mea-
surement of glacier surface velocity. Results obtained on
two glaciers located in the French Alps are compared and
validated with ground measurments.
