MULTISENSOR MAPPING USING SAR IN CONJUNCTION WITH OPTICAL DATA

In the nineties, operational SAR satellites like ERS-l, JERS-l or Radarsat will provide microwave image data. Simultaneously, existing and future satellite missions will acquire optical image data. This paper focusses on the feasibility of stereo fusion of SAR and optical image data, which is difficult due to the different radiometry of the images. A first experiment on multi-sensor stereo mapping using the RSG software package to combine a multi-parameter airborne SAR image with a SPOT HRV image of moun tainous terrain in the Austrian Alps is presented. Basic steps and results of 3-D data extraction from this image pair and subsequent quality control are illustrated.
