Sentinel-1 radar data
The C-SAR instrument is capable of measuring earthquake-affected regions, land subsidence, uplift ... through the creation of interferometric synthetic-aperture radar (InSAR) images.
The analysis of phase changes between two or more synthetic aperture radar images taken at different times is able to create maps of the digital elevation and measure the land surface deformation of an area. High spatial (20m) and temporal (6 days) resolutions allow S1 to improve on current InSAR techniques and provide systematic continuity to the data.
