Orthophotoquads for Arizona Land-Use Mapping and Planning

After initial evaluation of National Aeronautics and Space Administration (NASA) high altitude aerial photography in 1971, the interest in application of high altitude coverage of Arizona resulted in an agreement between NASA, U.S. Department of the Interior, and the State of Arizona, to conduct the Arizona Land-Use Experiment. Space imagery and photography, high altitude aerial photography, training of state agency personnel, orthophotoquad production, and preparation of a manual of results are principal components of the agreement. Numerous applications for the photography, orthophotoquads, and space data are under development in a coordinated program involving key state agencies. The Arizona State Land Department routinely uses the high altitude photography and plans to incorporate 1:24,000 scale orthophotoquads into a comprehensive set of maps and thematic overlays for use in its land management program. Uses by the Arizona Highway Department include updating of photogrammetrically prepared transportation planning maps and highway alignment digitization from the orthophotoquads.
