Résumé du projet

GEOSUD aims to boost uses of satellite imagery by researchers and public policy actors in the fields of environment, agriculture and land development. To this end, the project consists of setting up an earth observation Data and Services Infrastructure (DSI) and accompanying user communities. The project started in 2011 and will be completed by the end of 2019. The investment phase was extended until the end of 2017. GEOSUD made it possible to acquire high spatial resolution images with an “all public actors” license. These include annual coverage of the national territory since 2010 and Pléiades images on areas at stake. In 2015, a receiving station was installed in Montpellier with a 1st reception terminal for SPOT 6-7 images. Six partners formed a consortium to purchase a base volume of SPOT 6-7 telemetry for 5 years. These investments now allow to continue producing national coverage and to acquire SPOT 6-7 images on demand worldwide. A 1st version of the DSI provides access to the entire GEOSUD archives and to new images. A 2nd release planned for the end of 2017 will provide users with on-line processing capabilities on high-performance computing environment. Methodological and thematic researches have been carried out within the consortium to assist in the development of the equipment. Training materials and courses for imagery management and thematic applications, including for distance learning, have been developed. At the end of 2016, GEOSUD comprises 438 members and 600 people have opened a user account. As of 2012, GEOSUD has contributed strongly with CNES and CNRS INSU in bringing out the Theia Land data Centre. Theia enabled GEOSUD to increase its capacity for action and to structure the national community in a much more ambitious way. These efforts are being pursuing since 2016 on an even broader scale to create a national research infrastructure that will bring together the 4 data centres and a national image access mechanism partly based on GEOSUD.
