The objective of this study was to determine if the quality of the ERTS imagery could be improved by averaging successive passes over the same physical area.

The U.S.G.S. designated five passes over two areas of study: Washington, D. C. and Phoenix, Ariz., with the requirement that optimized imagery be derived directly from the EROS Data Center Bulk CCT's. The Mead system goes directly from the Bulk CCT's to hard-copy print-out, thereby by-passing any intermediate electronic, electro-optical, or photographic processes which may lead to image deterioration.
