    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.

    The subject of the presented work is analysis and evaluation of usefulness of high resolution radar data in the context of creating land cover maps for urban areas and checking the suitability of the proposed method of classification. The potential of mapping and interpretation of high resolution TerraSAR-X data was examined and an optimal way of processing this data from the point of view of obtaining information about land use and land cover for urban areas was presented. The attempt of developing guidelines for the selection of appropriate data set was also made to carry out the correct classification and suitable analysis. For this purpose, data sets of six, single-polarized TerraSAR-X images were analyzed in detail. The images acquired with different parameters and from different types of orbits (descending and ascending), for an area of Cracow were used. On their basis, an automatic classification scheme of high resolution radar images was developed, in objectoriented approach using parametric method, based on a hierarchical database decision rules. Additionally, benefits from an integration of radar and optical data, in order to increase separation chance of land cover elements were checked.
