Abstract: This report describes the geometric image quality of the LPIS-based RapidEye level 3A product in the context of the Common Agriculture Policy (CAP) Control with Remote Sensing (CwRS) Programme. This product is similar to the RE standard level 3A product, but the standard RapidEye planimetric auxiliary data is replaced with a set of ground control points derived from the LPIS vector data. Based on the current analysis there are two issues that most likely driving the differences in the geometric quality of the provided tiles: the heterogonous quality of the input height data and a low polynomial order for reprojection to the Gauss-Krueger. In order to comprehensively verify these hypotheses, the quality analysis must be repeated. Based on the limited RapidEye sample images, the accuracy of the LPIS-based RapidEye level 3A products is within the RE product specifications accuracy (1-D RMSE of 6.5m) provided the shift elimination based on the set of well-distributed ground control points.
