Multipart Polygon

Multipart Polygon refers to one vector feature made up of several separate polygonal geometries grouped into a single spatial feature. Individual parts of a multipart polygon may possess their own locations and shapes, but they all share identical feature attributes. Contrary to single polygons, individual polygonal parts within a multipart polygon can be totally dislocated from each other.

A multipart polygon geometry is widely applied when one geographic entity encompasses several areas located separately from each other. The examples of such entities are clusters of islands, disjoined territories of conservation areas, dispersed property lots, or administrative divisions with isolated territories. For GIS software, it is beneficial to store these entities as one multipart feature to ensure unified attribute handling and accurate reflection of the actual entities. Additionally, multipart polygons are handy for spatial database storage, cartographic mapping, land administration, and geospatial analysis purposes. GIS specialists may split multipart features into separate polygons whenever necessary or join several polygons into one multipart feature.
