5. CONCLUSIONS 
Satellite data acquisition systems for mapping are 
now in the state of rapid development. This will not 
only make images available to the mapping 
community, but it will also add a boost to value 
added technology development. New techniques of 
stereo-satellite-image matching for DTM generation 
will compete with radar interferometry, and geo- 
coding of satellite images will compete with digital 
  
orthophoto mapping via digitized aerial photos in the 
integration of image data into geographic informat- KEY 
ion systems. [eye 
This is an exciting time for photogrammetry. ISPRS | ABS 
is called for in comparative testing of the widely | 
differing technologies now becoming available for High-
