Abstract

The main subject of this paper is an assessment of the potential to generate large scale digital elevation models by means of interferometric processing of ERS SAR data. A DEM of the entire Czech Republic has been produced using Tandem data preferably from the winter period 1995/96. The corresponding processing steps, with emphasis on data selection and mosaicking, are presented. The results are compared to reference elevation information and show a typical vertical accuracy in the order of 10 m, indicating the potential of the methodology to generate large area DEMs on principle. Finally, elementary limitations are discussed
