Disaster Risk Reduction

NextGEOSS’s Research pilot on Disaster Risk Reduction (DRR) aims to provide an enhanced multi-hazard risk assessment framework based on the statistical analysis of long time series of data accessible through the NextGEOSS Data Hub. Focus will be given on landslide events monitoring and landslides susceptibility estimation. More information can be found on https://nextgeoss.eu/pilots/disaster-risk-reduction/ In this pilot, three discrete steps are taking place: 1. Generation stack of interferograms derived from SENTINEL-1 images for a specific area of interest, calculated on the NextGEOSS cloud environment; 2. Stack of interferograms are used as input data for the generation of line-of-sight ground velocities based on Persistent Scatterer Interferometry technique, processed on the NextGEOSS cloud environment. This component provides ground velocities as output feature data (WFS) with ground deformation information embedded; 3. The third step updates the landslide inventory, based on the ground velocities (Step 2) and a specific reasoning (e.g. volume, slope, LU/LC). After the identification of new landslides, NOA’s enhanced landslide model runs and provides the updated landslide susceptibility map (WMS). This model runs on NOA’s dedicated server based on the ground velocities;
