Context and objectives
The objective is to assess the possibilities and the limitations of the use of SAR images (ERS and RADARSAT) in the currently operational control system developed by the Ministry of Agriculture - CTS in the framework of the Common Agricultural Policy.
This SAR study focuses on 4 specific issues related to this application:
Expected scientific results
A SAR images preprocessing chain has been adapted to be incorporated in the crop control system of the Belgian Ministry of Agriculture. The use of SAR images in addition to the available optical images increases the efficiency of the fraudulently declared parcels detection. The classification waterfall strategy developed in this project allows to increase the efficiency of the control for any remote sensing data. Indeed this is improved the control when achieved by optical images as well through the combination of optical an radar images. A computer-assisted photo interpretation method dedicated to the SAR data and adapted to the environment of the Ministry has been succesfully proposed.
Based on the results obtained for the year 2000, some conclusions can be translated in practical recommendations:
