Radar satellite systems represent a viable solution for monitoring geomorphic processes and slope instabilities in alpine environments as they cover large areas and have a sufficient spatial and temporal resolution. In this paper, we present some results of the Interreg project SloMove that focused on monitoring slow mass movements in high alpine areas using terrestrial and remote sensing techniques. We found that DInSAR is well suited for monitoring of geomorphic processes if the test sites are carefully selected, matching the geographical situation of the slope with the geometric conditions of the satellites. Movement trends and areas of increased activity can then be identified with high reliability. However, satellite remote sensing needs to be supported by terrestrial measurements, particularly in the case where the results aim for supporting civil protection purposes. The validation with groundbased methods, in our case DGNSS and TLS, showed that the magnitude of displacement cannot be assessed with the same accuracy and that punctual data represent good reference points for comparisons of the different measurement techniques.
