INSAR TECHNOLOGY FOR DEM CONSTRUCTION AND DISPLACEMENT ESTIMATION
Ground displacements in area of intensive oil production induced by crust blocks movement influence on pipelines leading to its destruction. Processing of great archive of ENVISAT\ASAR and ALOS\PALSAR radar data was carried out. Digital elevation models of oilfields in KHMAO region were constructed. Surface displacements caused by seasonal water level fluctuation were detected. Common principles of radar frames selection and interferometric processing features were formulated.
