GEOMETRIC AND CARTOGRAPHIC ACCURACY OF ERTS-1 IMAGERY

The potential applications of the RBV and MSS images in cartographic mapping is limited by resolution rather than by geometric fidelity. A bulk RBV image from ERTS-1 should have sufficient geometric fidelity to meet the National Map Accuracy Standards for mapping at 1:500,000 scale. With four or more control points for distortion correction, a bulk MSS frame could also be processed to meet the NMAS requirement of 1:500,000-scale mapping. In digital processing, a relative positioning accuracy of plus minus 55m should be attainable for both RBV and MSS images. High-order polynomials were found to be very effective in modeling the total geometric distortions in both the RBV and MSS systems.
