DEFINITION

What is a Voronoi Diagram?

A Voronoi Diagram partitions a plane with points into polygons such that each polygon contains exactly one generating point and every point in a given polygon is closer to its generating point than to any other.

A Voronoi Diagram (also knows as Thiessen Polygons) can be used to show catchment areas for a group of facilities.
