The CopernicusLAC EO Service activities include the development of twelve innovative services for disaster risk reduction (DRR) based on Copernicus Sentinel satellite data. These services will be integrated into the future CopernicusLAC Panama Centre, which will provide users in Latin America and the Caribbean (LAC) access to the information, services, and processing capabilities established by the Centre in the region.
The geohazards theme will leverage the power of Synthetic Aperture Radar (SAR) from Copernicus Sentinel-1 to detect a wide range of ground motion phenomena. During the development phase, the synergies between SAR interferometry, optical remote sensing, geological and morphological terrain analysis, asset exposure, and artificial intelligence will be leveraged to develop three specific services for DRR in the LAC region. These services will be related to landslides as well as the detection and monitoring of other geological hazards, such as seismic activity, subsidence, and active faults.
Landslide susceptibility mapping
This service integrates multiple data sources (geological layers, Digital Surface Models, EO, and landslide inventories) into a Machine Learning model to derive landslide susceptibility maps. The product is integrated with average velocity data from the Interferometric Stacking service to derive a map of potential landslide hazard.
Interferometric Stacking
Service to generate interferometric stacks from Copernicus Sentinel-1 data. Products include average ground motion rates per pixel and decomposition into vertical (up-down) and horizontal (East-West directions) ground motion components.
PSI Geometric Decomposition
Service for extracting the actual components of terrain motion in vertical (up-down) and horizontal (East-West) directions from the output of the SNAPPING-PSI service.
SNAPPING-PSI Full Resolution
Ground motion mapping and monitoring service at full Copernicus Sentinel-1 resolution using a Persistent Scatterer Interferometry InSAR technique. Products include average ground motion rates and displacement time series at point targets.
SNAPPING-PSI Medium Resolution
Service for terrain motion mapping and monitoring, using Persistent Scatterer Interferometry InSAR technique over large areas. Products include average ground motion rates and displacement time series at point-like targets.
