# GRASS Help System

area - A homogeneous region containing data having the same category value. An area (a.k.a., polygon) is formed by the series of arcs outlining its perimeter. GRASS vector format does not store polygons explicitly; when used to describe vector data, therefore, areas refer to area edges. More generally, area can refer to a geographically defined region (rather than to a region defined by a category value).
