Satellite systems are increasingly efficient and generate a large volume of Earth-observation data useful for land and natural resources management and a better understanding of the 21st-century global challenges such as climate change and sustainable development. 

 

However, the added value of these data lies in their analysis to meet the needs of end-users, whether they are researchers, entrepreneurs, local authorities, or citizens. It, therefore, requires identifying the end-users needs to create or adapt satellite-based data tools to be close as possible to their requirements.
