Abstract
Abstract Methods of SAR interferometry data processing can detect and monitor low-amplitude motion of the earth's surface having the natural or man-made nature. The method of Persistent Scatterers Interferometry (PSI) successfully used for monitoring above mentioned processes in many cities around the world. The results of PSI technologies allow to providing geodynamic zoning of urban areas and identifying the objects exposed to linear deformation - separate objects, extended linear features (e.g. subway). The paper present the results of PSI COSMO-SkyMed data processing for Astana city (capital of Kazakhstan), including the displacement distribution for individual buildings and structures, and areal coverage analysis of surface movements. Data of ENVISAT ASAR images for Almaty city received from ESA grant C1.P15390 “Spatio-temporal analysis of surface displacements in urban areas with high seismic risk by SAR interferometry data”.
