Central Atlantic regional ecological test site: A prototype regional environmental information system

During this reporting period progress was made on a Level III land use classification to respond to more detailed user requirements and to exploit the fullest resolution potential of ERTS data. A small area of the Norfolk-Portsmouth SMSA test site was mapped on Level III, with the use of high altitude aerial photography, topographic maps, and other local maps. It was also decided to attempt to identify as many Level III land uses as possible during the land use mapping of CARETS from ERTS.
