The ERS programme celebrated its 30th anniversary on 17 July. Today, we are still exploiting ERS data and experts continue to work on improving the altimeter, radiometer and SAR data the programme acquired.
This document is intended for geologists who are interested in broadening their knowledge of interpretation of imaging radar data. It introduces imaging radar as it may be used by technicians and image interpreters. Interferometric SAR is briefly treated, with some basic and practical hints. An illustrated application study on land subsidence is included.
