AVAILABILITY AND COMPARISON OF DATA FROM SENTINEL-1 SATELLITES IN AREAS OF INTEREST IN THE CZECH REPUBLIC AND SUDAN

Popis výsledku v původním jazyce

The article is focusedon the methodology of processing interferometric images andassociatedchallenges with the processing. The article also contains useful links with explanations that can be used forprocessingdata from the Sentinel-1 satellite. To emphasize the data limits of Sentinel-1, several areas of interest were chosen for comparison –in the home environmentof the Czech Republic, the Bílina quarry area, and the Žatec area were selected. For subsequent comparison, arid areas with a rich history located in Sudan were selected.The colleagues of the author from the Faculty of The Environment of Jan Evangelista Purkyně University participate in expeditionsthere. Each of these locations is limited by different parameters–the areas in the Czech Republic are mainly limited by location because of occurring vegetation. Sudan's regions, on the other hand, are arid but are limited by insufficient coverage by capturing the Sentinel-1 satellite. To create digital height models from Sentinel-1 satellite data, it is necessary to search for data with sufficient coherence of images, and parametersof the amount of vegetation with a periodbetween individual images play an important role. The areas were compared with each other and with the commonly available SRTM elevation model, both from a visual point of view –where digital height models and shaded surface models were created, as well as statistically using RMSE.
