DEFINITION

What is a Thiessen polygon?

Thiessen polygons are generated from a set of sample points such that each polygon defines an area of influence around its sample point, so that any location inside the polygon is closer to that point than any of the other sample points.

Thiessen polygons (also called Voronoi Diagrams) can be used to show catchment areas for a group of facilities.
