Abstract: This report summarizes the initial evaluation of the geometric characteristics of the single sample the radiometrically corrected Kompsat-2 image acquired over the JRC Maussane Terrestrial Test Site. The objective of this study is threefold: (1) to evaluate the planimetric accuracy in a routine basis production of orthorectified Kompsat-2 imagery; (2) to determine the optimal number and spatial distribution of the GCPs (Ground Control Points) for the Kompsat-2 orthorectification process; (3) to check if the orthorectified imagery of the Kompsat-2 optical sensor fall within the required accuracy criteria for the CwRS 1:10.000 scale of absolute 1-D RMSE of < 2.5m. Based on the limited sample images, the Kompsat-2 orthoimage product accuracy meets the geometric specification of 2.5m (1D) RMSE corresponding to EU technical requirements on the condition of using at least 12 well-distributed ground control points for image correction and orthorectification.
