    Orthorectification and geometric verification of high resolution TerraSAR-X images
    (2011) Badurska, Monika
    TerraSAR-X is a German radar satellite, which was launched in June 2007. The satellite is equipped with a modern SAR system using the X band microwave radiation frequency and is capable of acquiring very high resolution SAR images independent of weather conditions and illumination. The paper presents the results of geometrical correction of high resolution TerraSAR-X images. The research was based on images acquired in HighResolution SpotLight mode in single polarisation HH with spatial resolution about 1 m. In orthorectification process the data supplied by the distributor in the SSC format was used. The results of orthorectification using various amount of ground control points was checked. The influence of the digital terrain model used in orthorectification process was also analysed. The last part of the work presents verification of geometric precision of geocoded product (EEC) generated by the distributor.
