Abstract: This report summarizes the initial outcome of the geometric quality testing of the panchromatic, pan-sharpening and multispectral THEOS images (level 1A and 2A) acquired over the JRC Maussane Test Site for the Common Agriculture Policy (CAP) Control with Remote Sensing (CwRS) Programme. Based on the limited K2, THEOS and DMCII sample images that were made available to us the THEOS PAN orthoimage can reach 2m accuracy provided that a dedicated rigorous model based on at least 9 well-defined, well-distributed ground control points (GCPs) of high accuracy (i.e. RMSEx,y < 0.90m) is applied; while the orthorectified THEOS 1B MS product accuracy can reach 6.8m, provided that a dedicated rigorous model based on at least 9 well-distributed GCPs of appropriate accuracy is applied
