WebThiessen proximal polygons are constructed as follows: All points are triangulated into a triangulated irregular network (TIN) that meets the Delaunay criterion. The perpendicular bisectors for each triangle edge are generated, forming the edges of the Thiessen polygons. WebThiessen Polygons and Voronoi Diagrams are pretty much the same for calculation in a GIS application. Voronoi lines are drawn by using perpendicular lines from all three edges of Delaunay Triangles. The intersection of three lines of a triangle will be a new node. In the end, these nodes create polygon shapes which are Voronoi Polygons.
