| Description
| - Radar interferometry (InSAR) method uses radar images for deformation monitoring of a large area. Four ENVISAT stacks of the ASAR images acquired from 2003 till 2009 provided by ESA were processed. The processing of the whole images would be very time and memory consuming, that's why only cuts covering the area of interest were created. These cuts were coregistered to a selected master in order for all possible interferogram combinations to be created. The examined area of interest is the built-up area of Prague city. Some subsidences occurred there in the past, mainly because of the human activity. Since several tunnels were built after 2000 and others are still under construction, there is an assumption of the deformation within examined area. The permanent/persistent scatterers (PS) method was used for deformation detection. The processing was performed by IPTA (Interferometric Point Target Analysis) package, which is a part of the GAMMA software. Only appropriate point targets were used for further processing, while the rest of points are omitted. Almost all available images can be used compared to the conventional interferometry method in which the critical baseline requirement must be fulfilled otherwise the interferograms are totally decorrelated. The aim of the project is the determination of the unstable areas caused either by the natural conditions or by the human activity (e.g. tunnels construction).
