Interferograms and time series collection on Maghreb 2014-2022
Three types of products are made available for each orbit portion processed (see <a href=" https://formater.pages.in2p3.fr/flatsim/ " target="_blank"> detailed description </a> )
- "INTERFEROGRAM": this brings together the differential interferograms, wound and unwound, in radar or terrain geometry, filtered or not, at different resolutions, as well as the atmospheric correction maps used and spatial coherence for each interferogram.
- "TIMESERIES": this includes maps of movement in time series and average speed, according to the satellite line of sight (LOS), and quality indices of time series processing.
- "AUXILIARYDATA": this directory contains maps indicating the LOS vector, the DTM in radar geometry, at different resolutions, the radar-field geometry transcoding tables, and temporal coherence, as well as a set of figures and parameter files specific to the processing of the time series.

- Purpose
-
The main aim of this project is to quantify tectonic deformation across the Maghreb, in the African/Eurasian convergence zone. In particular, it aims to estimate the spatial distribution and temporal evolution of interseismic deformation or deformation associated with recent earthquakes on active faults, from the coast to the Saharan platform. Secondary themes (landslides, coastal subsidence, dune movement in the Sahara, anthropogenic deformation associated with major structures, natural resource extraction, agriculture, etc.) will also be addressed.

- Statement
-
These collections of interferograms and displacement time series are produced by CNES as part of the FLATSIM service. This service is developed in collaboration with the ForM @ Ter Data and Services pole and the ISTerre, LGL-TPE and IPGP laboratories. The radar images used come from the TOPSAR Sentinel-1 archive (Copernicus data). The calculations are made from the NSBAS interferometric processing chain
