Introduction 

A Voronoi diagram divides a plane containing x points into x convex polygons containing one of these points. The first tutorial explains how a Voronoi diagram is constructed. The second one shows how to add it to a map in QGIS.   

Tutorial(s) 

Voronoi diagram theory  

The following tutorial explains how the Voronoi diagrams are created.  

• What is a Voronoi diagram and how is it constructed   Hugo Ledoux: “Triangulations & Voronoi  diagram”    Language(s): English  Time: 17min 23s   Chapters: Voronoi diagram, Delaunay triangulation, duality between the Voronoi diagram and Delaunay triangulation, construction of a Delaunay triangulation and Voronoi diagram  https://3d.bk.tudelft.nl/courses/geo1015/les/2.1/  

Voronoi diagram in QGIS  

A Voronoi diagram can also be constructed in QGIS.
