We have acquired TSX high-resolution spotlight images with several incidence angles. The TSX orbit data is used to estimate the absolute elevation height of some deployed corner reflectors, but also some known building structures. The estimated height is surprisingly estimated to within a few decimeters accuracy. This technique can be used to extract ground control points that may be used further in interferomtric SAR data processing.
