banner1.pngVoronoi Tesselation and Delaunay Trianglulation both perform spatial calculations on a set of irregular points. Voronoi Cells (sometimes referred to as Thiessen Polygons in the GIS world) make up a Voronoi Tesselation, which is the partitioning of a plane into polygons based on a set of points, so that for each point there is a corresponding polygon where the area in the polygon is closer to the corresponding point than any other point. Delaunay Triangulation is when a set of irregular points are divided into triangles, so that no point in the set is inside the circumcircle of any triangle created from the points.

 

Both of these processes have a bunch of really neat spatial analysis applications. In this article, we will talk about their implementation in Alteryx.

No plan works as expected and not every connection is obvious. Our team discovered this through the use of Alteryx and Neo4j.
