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.
