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 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
