Scientific paper

In the framework of European Agricultural Guidance and Guarantee Fund (EAGGF) each EU member have to yearly control a proportion of the subsidized surface. Since 1995, the use of optical remote sensing for this control increases and becomes one of the major civilian operational applications of remote sensing. In Belgium the Cellule de Techniques Spéciales belonging to the Ministry of Agriculture run an automatic system based on the classification of minimum three high resolution images acquired during the growing season. The time constraint of this operation is very severe as this 39 crop discrimination must guide the in-situ observation of the cultivated fields. This SAR study focuses on two specific and critical issues related to this application: Can SAR images substitute the summer optical image which is the main current time constraint for the information delivery? Can SAR images increase the current accuracy obtained from the optical images?
