Terrain measurement in the dragon-2 program

In the project 5297 under the theme "Terrain Measurement" within the ESA-MOST Dragon 2 program, our research focused on topographic mapping and deformation measurements with SAR data acquired by ESA missions as well as third party missions. SAR data was used to map the topography in mountainous area using interferometry and stereoscopy. Deformations due to slow landslide movements, urban ground subsidence, and deformation of large infrastructure elements were measured using D-InSAR and PSI techniques. Application of the RPC model in geometric processing of SAR data was explored. In this paper an overview of the studies undertaken is given and the achievements are summarized.
