The mission of DORIS is to establish an operational COPERNICUS (formerly GMES) downstream service to:

• Strengthen the effective exploitation of satellite data and technology for the detection, mapping and monitoring of ground deformations, chiefly landslides and subsidence.
• Integrate satellite and ground-based data and technologies to improve the understanding and forecasting of ground deformations.
• Raise the awareness of landslide and subsidence phenomena, and of the possibility of using space data and technology to monitor the deformations, and to help managing the problems caused by the deformations.
