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.
