The collection consists of a series of products (DSM, hillshades, quality maps) of interest for the Earth and environmental science community. It covers various sites and landscapes over the World. The dataset is an open collection with regular updates according to the availability of Pléiades stereo-imagery for science and/or public organizations and the generation of topographic products with the <a href="https://www.poleterresolide.fr/le- service-dsm-opt/" target="_blank">DSM-OPT on-demand service</a> . The collection is disseminated using FAIR principles under the Digital Object Identifier (DOI): doi:10.25577/0JGV-V947

The Pléiades Glacier Observatory (PGO) dataset collection is an initiative of the French Space Agency / CNES, of the Laboratory of Space Geophysical and Oceanographic Studies / LEGOS and of Institut National des Sciences de l'Univers / CNRS-INSU to facilitate access to Pléiades satellite stereo-imagery over glacier targets. The collection consists in Very-High Resolution (0.5m) Digital Surface Models (DSMs) and ortho-images for the glaciology community.

The objective of the project is to quantify and model the current deformations on the eastern edge of the Tibetan plateau. It focuses on deformations of tectonic origin, at the scale of active faults as well as at the continental scale, to address issues of the seismic cycle and uplift mechanisms of the Tibetan plateau. This project is also interested in non-tectonic signals present in time series (hydrological overloads in particular). 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.

This project aims to better understand the deformations of tectonic origin in the area of ​​the Okavango Delta (associated with the functioning of the Okavango rift and the East African rift), or of hydrological origin (linked in particular to the flood cycle. ), and the possible interactions between tectonics and hydrology in this region.

This project focuses on the study of the deformations associated with the Ozark aquifer (south of the Mississippi basin) subjected to strong variations in groundwater level, and in neighboring regions where significant seismicity is observed, at strong seasonal component (New Madrid), or linked to wastewater injections (Oklahoma). The objective is to better understand the geodesic signature of the hydrological cycle.

This project aims to better understand the seismic cycle of the Andean subduction zone in Peru and Chile and the crustal faults in the Andes, to follow the functioning of the large active volcanoes in the region (and to detect possible precursors to eruptions) , and to study the seismic, climatic and anthropogenic forcing on the dynamics of landslides in the Andes.
