Abstract
We have studied the geographic position of several high-resolution spotlight TSX images by investigating the location of deployed radar corner reflectors. Results show that the geolocation accuracy is better than the resolution cell in both azimuth and range directions. The same corner reflectors as well as distinct points on buildings are used to estimate the absolute height from stereo viewing spotlight TSX images to within a few decimeters accuracy.
