in case of cloudy areas in the stereo pair) of the gen- 
erated DEMs. The fusion of optical and inter- 
ferometric data for Land Use Classification seems to 
be very promising. In particular, the coherence im- 
ages give a significant contribution for the detection 
of different land cover classes. The first results ob- 
tained by the authors have been issued from a very 
simple data set. The procedure is going to be ex- 
tended to a bigger number of layers.

and the SPOT orthoimage used for the data fusion 
with the interferometric data.
