Thiessen polygon generation
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. WebThiessen 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 …
