Cartography and remote sensing are two disciplines that share several common characteristics. The techniques employed by both are usually supportive to other disciplines such as geology or forestry and are not usually applied in the absence of user prerequisites. Both are subdivided into professional subdisciplines such as photogrammetry, geodesy, and computer image processing. And both share a parallel series of endeavors--categorization, rectification, design, and publication. With the advent of digital cartography, the symbiotic relationship with remote sensing is further enhanced and the capability to perform sophisticated analysis using digital data bases will he extended to the point that instant customized maps, both conventional and video, will be common and widely available. The extensive knowledge of rectification by cartographers can he especially valuable when applied to remote sensing and will be essential to achieve optimum map projections and data overlay.
