This site, under construction, aims to facilitate the use of remote sensing data for the observation of land surfaces.

It therefore endeavors to propose tools allowing the exploitation of free data (Landsat, Sentinel-1/2, …) from processing carried out on free software (QGIS, Orfeo ToolBox, …). In addition to the software and processing that can be downloaded freely, you will also find training materials and tutorials, designed for various operational projects, as well as links to existing resources.
