COPERNICUS Global Land Products and Services provide an unprecedented amount of products derived from Earth Observation (SPOT-VEGETATION, PROBA-V, Sentinel 1, Sentinel 2 and Sentinel 3). The products and services encompass a large amount of products related to vegetation, water, snow cover, land cover etc… Those products are a great opportunity for using them in the monitoring and evaluation of the Sustainable Development Indicators (SDGs) required by the custodian agencies or many other applications by a larger user community. Prior to the integration of the COPERNICUS products into monitoring and evaluation of the SGG indicators, the products go through an in -depth validation and review process through international panel of reviewers. This presentation discusses the processes put in place by COPERNICUS to ensure the highest quality of the products.
