【Abstract】 Our Landsat Ground Station can receive, process TM (as well as MSS) image data from the Landsat 4 and 5 (U. S. A.), and produce systematically and geodetically corrected imagery.In order to certificate accuracy of its image products, an accuracy comparison has been conducted between geodetically corrected TM images produced by our ground station and U. S. NOAA based on 1:24000 topographic maps. In this paper the differing as well as common aspects of processing algorithms used in these two systems are highlighted and the general approaches for accuracy comparison of their products are illustrated. The comparison results show that the geodetic accuracy and internal geometric fidelity for both products are about the same.更多还原
