  1. 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.
  2. 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!
  3. I checked all this. I even tried in ArcGIS 9.3. But the problem is the same. But I found an other solution: A program, that connect the points automatically
  4. Hello, I have a lot of points (conturs of lakes), which I want to connect to Polygons. I created a new shapefile in ArcCatalog, added it to ArcGis, created a new template, started editing this template, connected all the points as "polygon", clicked finished the polygon and had my nice polygon. Sometimes, sometimes, my problems start here. Sometimes this works fine, then I wanted to save it. I clicked save and stop editing and suddenly the vertexes of my polygon are not at the some positions like my original contur points. I did not use all my points to create the polygon and it looks a bit like ArcGis 10 did interpolate between all my conturs-points automatically. I could not change this later by editing, too. Always when I click save editings, ArcGis does what it want and save its own version of my lakes. Any ideas? Best wishes
