Vicmap Features - Geomark Index Extent Polygon
Polygon extent of named or 'could be' named Victorian topographic features. Inclusions are rivers, water bodies, transport (excluding roads), geographic features and most of the Vicmap Features of Interest content. These features all reside within the Vicmap Framework Products. Features are combined to create one piece of geometry based on name and type. The extent table holds ALL features ONCE regardless of whether they were derived from a point, line or polygon.
