In future investigations we will extend our approach to slant range data. The extracted objects in the InSAR data could 
be matched with referring objects in a given 3D description of the scene. Afterwards, a geometric and radiometric 
[Ulander, 1993] correction of the SAR intensity is performed. 
The segmented regions might be incorporated in the phase unwrapping step. Shadow and layover areas, which 
correspond to high intensity and low coherence, could be masked. Only residues in the remaining data are considered. 
ACKNOWLEDGMENTS 
We want to thank Dr. Ender (FGAN-FHR Research Institute for High Frequency Physics and Radar Techniques) for 
providing us the InSAR image data. The data were recorded by the AER II experimental system of FGAN [Ender, 
1998]. We also thank Mr Konetzki of the survey department FIP-P1/V of the Flughafen Franfurt Main AG for kindly 
supplying us the paper map.
