ikleine Posted February 16, 2012 Report Share Posted February 16, 2012 Hello! I have ascending and descending TerraSAR-X images (3m resolution) of an area near equator. I extracted an SRTM3 (90m resolution) automatically with SARscape, geocoded (with SARscape 4.4) my images with the SRTM3 and compared ascending, descending and my groundtruth data of the area. Ascending and descending images seem to be shifted in west and east direction and they both don't fit with the groundtruth data. Do you have you any idea what could the reason of the displacement? Thank you for your help! Quote Link to comment Share on other sites More sharing options...
Administrators EmperoR Posted February 16, 2012 Administrators Report Share Posted February 16, 2012 are you aware bout the geometrical error because of terrain or the sensor? Quote Link to comment Share on other sites More sharing options...
ikleine Posted February 16, 2012 Author Report Share Posted February 16, 2012 I'm not sure if I understand your question... I think the position records of the sensor are correct. I assume the problem in the bad resolution of SRTM or the SARscape process. Quote Link to comment Share on other sites More sharing options...
