Multi-Temporal InSAR processing comparison in presence of high topography

Abstract

In this paper we compare the results obtained by three different InSAR tool packages, StaMPS, SARPROZ and P-SBAS (CNR-IREA) on G-POD for the processing of a mountainous area with up to 2,000 m high differences. For that we use two dataset ERS-1/2 and Envisat ASAR. The area (Sierra Tejeda, southern Spain) is located close to the coast line in the Internal Zone of the Betic Cordillera. The recent NW-SE convergence of the Eurasian-African plate boundary makes this area to belong to a large fold which continues active up to present. The uplift of the mountain ranges is mainly related to the development of folds in this regional compressive setting. This paper investigates and compares the velocity pattern obtained by the three different algorithms to help to constraint the geological hazard in this part of the Betic Cordillera.
