Main Page | See live article | Alphabetical index In geographic information systems, a coverage is a mapping of one aspect of data in space. It represents a "domain" (the universe of extent) in terms of charateristics expressing a range of values. For example: a satellite image derived from remote sensing might record varying degrees of light pollution. As a contrast to coverage data we find feature data, which concentrates more on the numerous characteristics of a spot and less on its spatial surrounds. This article is from Wikipedia.
