  skos:definition "The Voronoi diagram (also called a Dirichlet tessellation or a set of Thiessen polygons) is a partition of a metric space such that we associate all locations in that space with the closest object in that space, based on the specified metric. Thus, each object is the generator of a cell or tile, and the set of tiles covers the space or map. [Source: Encyclopedia of Geography; Voronoi Diagrams]"@en ;
