Využití satelitních snímků pro geologické mapování a strukturní analýzu

Sokolová, Anna

The use of remote sensing data is becoming very important in Earth sciences. Satellite images are invaluable for studying hardly reachable places on Earth and they can significantly help increase the efficiency of work in areas with existing field data . In arid areas where rocks are exposed and directly visible at the surface, a lithology contacts mapping can be done based on satellite images. An overview of the possibilities of processing multispectral images is included in the theoretical part of this thesis, as well as a description of previously known methods for performing structural analysis based on remote sensing data. As the main part of this thesis, a new method for finding orientations of planar geological structures including a quality control of the input data was developed and described. This method was then applied in the Bodonchin area of the Mongolian Altai where the metamorphic foliation and pegmatite veins were analyzed. The method showed good applicability in the given area despite its limitations which are also discussed in the thesis.
