DMCII Geometric Quality Testing for CAP Control with Remote Sensing Programme - Initial Findings

摘要

This report presents the geometric quality results recorded for the two samples of the DMC2 orthorectified products (processing level 1T) acquired over the JRC Maussane Test Site. It was shown that the average 1-D RMSE for the DMC2 L1T ortho product are 22m and 21m of Easting and Northing direction respectively (i.e. about 1 pixel accuracy), or 25m and 24m if point identification error is included. These values are valid if orthorectified SPOT5 Sumermode is used as reference data. These geometric quality results are very promising, however, it should be borne in mind that the tested DMC2 samples are very limited (i.e. two samples). Further testing is required, especially for diverse terrains and images characterised by high satellite inclination angle.
