Description: The main objective of the report is to assess whether images produced by Sentinel-2B sensor are suitable for usage in Control with Remote Sensing programme, specifically in the Common Agriculture Policy (CAP). The benchmarking presented herein aims at evaluating the usability of Sentinel-2B images for the CAP checks through an estimation of its geometric (positional) accuracy. Tests have been performed on Sentinel-2B data from the first pre-operational phase (June 2017), subsequently on data from the pre-operational hub (July 2017). See chapter 2.1. For that purpose, the External Quality Control of Sentinel-2B orthoimagery conforms to the standard method developed by JRC and follows a procedure already adopted in the validation of previous high and very-high resolution products.
