Optimization of satellite insar techniques for monitoring of subsidence in the surroundings of Karvina mine: Lazy plant

摘要

This paper deals with issues related to convenient monitoring of subsidence due to longtime mining activities of CzechKarviná Mine: Lazy plant, using satellite SAR interferometry (InSAR) techniques. It maintains approaches for optimizationsof differential InSAR, especially including available filtering possibilities. It was realized that current SAR satellites were notable to appropriately evaluate deep subsidence as it occurs in Czech mining sites. Other issues are related to the presence ofdense vegetation. Data from previous and only available L-band SAR satellite ALOS demonstrates its high potential in thisarea of interest. However, only a few acquisitions are available of the mining site disallowing usage for purposes ofcontinuous monitoring of subsidence in the area. Processing results of InSAR techniques of the Lazy plant are presented inthis paper.
