Identity

The topological overlay of a coverage (input) with a polygon coverage (identity). For each feature in the input coverage, the intersection with identity features is determined, creating new features of the same feature class as the input coverage. For example, a road (input coverage, arc feature class) passing through two counties (identity coverage) would be split into two arc features, each with the attributes of the road and the county it passes through. Compare with intersect and union.

A unique name of an individual person. Since the legal names of persons are not necessarily unique, the identity of a person must include sufficient additional information to make the complete name unique.

A unique piece of information which is recognized as denoting a particular entity within a security domain. The identity information is only unique within the domain [ECMA138].
