Data in Use
ERS-1, ERS-2, Envisat, Radarsat-1, Radarsat-2, ALOS, Cosmo-SkyMed, TerraSAR-X
TRE processes satellite radar imagery to provide surface displacement maps to regional governments for landslide mapping. Instability maps are interpreted by geological institutions to delineate landslide boundaries and detect changes in the rate of ground movement, ultimately identify areas of potential hazards, as well as updating existing landslide inventories. This unique service provides high density data and frequent updates.
Wide area monitoring of ground instabilities provides an early detection tool for the identification of areas at elevated risk of landslides.
Added value through GMES
Sentinel-1A will ensure the continuation of SAR data acquisition, required for the landslide mapping service. The launch of Sentinel-1B will create a more robust service with the possibility of weekly updates.
