directions can be locally optimised, based on DEM and maps 
from a GIS. 
Especially in dense urban areas, context information provided 
by GIS should be integrated in the analysis of SAR data. 
Particularly, high resolution DEM are useful for the mapping of 
the map data to the correct location in the data. The influence of 
the vegetation should not be neglected even in a dense urban 
environment. With a 3D vector representation of man-made 
objects, possible locations of strong scattering can be detected. 
Detailed information concerning the surface material of objects 
is usually not available. We recommend exploiting vector data 
of a 3D city model together with 3D raster data of the 
vegetation for the event-driven acquisition and analysis of SAR 
images. 
ACKNOWLEDGMENT 
We want to thank Prof. Dr. Ender and Dr. Brenner (FGAN- 
FHR Research Institute for High Frequency Physics and Radar 
Techniques) for providing the InSAR data acquired with the 
AER-II sensor (Ender, 1998).
