New sensors benchmark report on KOMPSAT-3A : geometric benchmarking over Maussane test site for CAP purposes

Imagery collected by KOMPSAT-3A satellite can be potentially used in The Common Agricultural Policy (CAP) image acquisition Campaign. The qualification and certificate is conducted by performing benchmarking tests, i.e. it has to be checked whether the planimetric accuracy of the produced orthoimages does not exceed certain values regulated by JRC. Therefore, a benchmarking test was carried out based on two KOMPSAT-3A imagery collected in February 2017 and March 2018. The first part of the report (chapter 2-6) describes in detail how the tests were performed, i.e. the auxiliary data, methodology and workflow used as well as outcome from the Internal Quality Control (IQC). The second part (chapter 7-9) deals with External Quality Control (EQC) and conclusions made on the basis of this assessment with regards to the VHR Image technical specifications criteria [iii]. While the first part, i.e. production of ortho imagery, was carried out by external an contractor (European Space Imaging - EUSI) the second part, i.e EQC, was performed by Joint Research Centre (JRC). In this way an independent and objective test was assured.
