Short summary
Satellite interferometric synthetic aperture radar data have proven effective and valuable in the analysis of urban subsidence phenomena based on multi-temporal radar images. This technology can be considered operational thanks to a regular acquisition plan and the access to significant processing power for a regular update of the information over large areas.
