Abstract
Data base management concepts applied in an established multicounty regional planning commission are identified and reviewed. The need for data base management is noted. Data base applications are examined, as used and interralated in described work programs of environmental planning—including air quality, water quality, and floodland management—and of related land use planning. The existing data structure and actual data file content are reviewed. The organizational setting is described, and the evolution of data base design is traced from large-cell data storage, to small-cell data storage, to digitized storage of irregularly shaped cells. Comparisons to state-level data base development for natural resource management are noted. The prognosis for overlay of areal data with line and point data is described, as is the potential use of optical scanning equipment for data entry of mapped information.
