CARTOGRAPHIC UTILITY OF SPACE PHOTOGRAPHS Frederick J. Doyle In October 1971, an International Symposium on Orthophotomapping was held in Paris, France. At that time the theoretical basis for preparing orthophotomaps from space photography was presented (1)*. Also presented were the characteristics of the imaging systems to be carried on the Earth Resources Technology Satellite (ERTS-1) and the Skylab. This was followed by a projection of the cartographic applications which could be accomplished from these records. The ERTS-1 spacecraft was launched in July 1972 and has been oper ating continuously since that time. The three manned occupations of Skylab have been completed, and all data have been obtained. Though it is still too early to reach final conclusions on the value of these records, it is appropriate to review what has been accomplished and what has been learned about the utility of these types of space photographs for cartographic applications. Theoretical Basis The major advantages of space photography for preparation of ortho phot omaps are: 1. Narrow angular field. This reduces image displacements due to topographic relief and makes possible the production of orthophoto products without the necessity of differential rectification. 2. High image resolution. This is made possible by the combination of narrow-field optical systems and extremely stable vibration-free platforms. 3. Synoptic view. The ultra-high altitude of space vehicles makes possible a wide area of coverage per frame despite the narrow angular field. Counteracting these advantages are: 1. Small image scale. Despite relatively long focal lengths, the extreme altitude produces small-scale images. ♦Numbers in parentheses denote references.
