About the Disaster Risk Reduction Pilot of NextGEOSS

Info: This site is providing access to NextGEOSS’s DRR products. Namely, it contains line of sight ground velocities estimated at selected points characterized as Persistent Scatterrers (PS), extracted from time-series of Synthetic Aperture Radar imagery. Each PS contains information on the evolution of the deformation during the observation time-span, a linear fit to these deformation values to estimate the annual deformation rate and a quality metric that corresponds to the standard deviation error of this velocity estimate. The analysis was conducted using the Persistent Scatterer Interferometry technique, with a variant implementation of StaMPS (Stanford Method for Persistent Scatterers). Users are free to view and download the ground deformations (velocities), request new service for another Area of Interest and provide feedback to the provided outcomes.
