Unit

## Definition

A specific geographic unit of a defined Unit Type. A geographic unit may change its name, composition, or geographic extent over time. This may be tracked by versioning the content of the geographic unit. Normally a new version of a geographic unit would have a geographic (spatial) overlap with its previous version (a city annexing new area). A geographic unit ends when it is no longer a unit of the same unit type.
