Figure 7: Geocoded image data: multispectral SPOT XS, spectral band 3 (left) and ERS-1 SAR image (right). 
Certain improvements of achieved results seem feasible 
through a more sophisticated processing of the data. In 
particular, future activities will be related to the 
implementation of alternative image matching algorithms. 
Emphasis shall be put on their applicability for SAR 
stereo pairs including images from different SAR sensors. 
Filter mechanisms for SAR image data have to be 
considered in order to reduce the SAR speckle noise and 
to provide better conditions for automatic SAR image 
matching.
