The Use of Air Photo Mosaics as Simulators of Spacecraft Photography in Land Use Mapping

摘要

The study investigates some of the potential limitations on land use mapping in the Pacific Northwest which may result from the anticipated small scale of future orbital imagery. Since high resolution orbital altitude photography of the area is routinely unavailable, a 1:400,000 photomosaic is used in simulation. Two scales of mapping are carried out and tested: general macro land use and thematic agricultural land use, the former by R. D. Rudd and the the latter by R. M. Highsmith, Jr. The only magnification employed was that achieved through the use of a 2x hand lens during the mapping. Substantial mapping potential is indicated despite the small scale of the photomosaic and a mapping classification is proposed. (Author)
