Coverage data
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 .
