blue arrow DATA DESCRIPTION

ESA is offering, for scientific research and application development, access to archive and new tasking data from ResourceSat-2 data upon submission and acceptance of project proposal. These products are available as part of the GAF Indian Satellite Imagery products.

ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project
