Ground Deformations Risk Scenarios: an Advanced Assessment Service
Date du début: 1 oct. 2010,

"DORIS is an advanced downstream service for the detection, mapping, monitoring and forecasting of ground deformations, that integrates traditional and innovative Earth Observation (EO) and ground based (non-EO) data and technologies. The service delivers innovative products tailored for Civil Defense authorities. DORIS integrates state-of-the-art technological and scientific capabilities with existing European upstream services, complies with guidelines provided by the Emergency Response Core Services Interdisciplinary Group, and is linked to existing Core Services, including SAFER and GMES EMERGENCY. DORIS goes beyond the state-of-the-art technologies used to detect, map, monitor and forecast ground deformations. DORIS uses the unique ERS-1/2 and ENVISAT C-band SAR archives to provide unprecedented, very long time-series of ground deformations. DORIS evaluates new SAR sensors, including ALOS, COSMO-SkyMed and TERRASAR-X, exploiting the different bands (L/X), the significantly reduced revisiting time, and the higher spatial resolution offered by these sensors. DORIS moves forward the integration of satellite and ground-based SAR interferometry, coupled with GPS measurements and geophysical probing. DORIS exploits multi-spectral images to map ground deformations, to identify the elements at risk, and for dynamic risk scenarios design. Finally, DORIS investigates the possibility of using thermal images for the assessment of landslide susceptibility and hazard. DORIS will be tested in six study areas in Europe. Successful application of the service in these areas guarantees that the downstream service will work in Europe. DORIS will provide a business model for long term self-sustainability of the service; the project is proposed by a unique team of public administrations, research institutes, and enterprises with experience in EO technologies for Civil Defence applications. DORIS favors knowledge and technology transfer, and will stimulate European competitiveness."
