The Institute of Computational Technologies of SB RAS (ICT SB RAS), Novosibirsk, Russia The article devoted to the developing the software package for the processing radar images. It consider the ability of the visualization, configuration and running algorithms of main stages of the Persistent Scatterer method. The integration with the massively parallel processing system had shown the fast execution of calculations of the ground displacement algorithm. The paper includes main scheme of data streams routing in the Apache Spark tasks to demonstrate the network data swapping between system components in the real-time calculations. The software implementation presented as a web portal based on ReactJS+Redux components, including the automatic downloading and updating the Sentinel-1A radar database within native RESTful API. Using the approach of the Apache Spark code development paradigm allowed achieving the high performance in low execution time of calculation stages.
Mots-clés : monitoring of the ground displacements, radar interferometry, massively parallel processing, radar satellite imagery.
