    Sentinel-1 Interferometry Systemin the High-Performance ComputingEnvironmentMilan Lazecky, Fatma Canaslan Comut, Yuxiao Qinand Daniele PerissinAbstract This paper describes the architecture of the system for monitoringdeformations based on interferometrical processing of Sentinel-1 satellite data usingspecif i c software installed at the facility of the Czech national supercomputingcenter (IT4Innovations). The system is ready for Big Data storage and processingand leads to partially autonomous competitive environment for following defor-mation monitoring projects. The processing chain is prepared to be performed usingSarproz software where the reader of specif i c Sentinel-1 Terrain Observation withProgressive Scans in azimuth data was newly introduced—the reader implemen-tation is described in the paper. First application of the system has been applied tosubsiding area of Konya city in Turkey. The processing was performed using asmall fraction of the supercomputer power, i.e. using 23 processors running at2.5 GHz speed, and led to results estimating subsidence in Konya city during 2014–2015—a subsidence of Konya buildings in the rate of more than 6 cm/year has beenevaluated, that is slightly more than the expected values from previous analyzes.The processing strategy of the described system is demonstrated in this case study.Keywords Satellite radar interferometry ?
