Voronoi Diagram

Glossary Term

Centre-referential partitioning of space, in which all points in a 3D cell rest closer to the centre point than to the other centre points.

Voronoi diagrams decompose space into cells depending on specific centre points. In this case, the cells are geometrically designed in the way that the distance between all points within the cell to its own centre point is shorter than to the centre of the adjacent cells.

In the field of cartography, this technique is applied on the basis of two-dimensional space for the distribution of information around a reference point.

The Austrian wind load map according to EN 1991‑1‑4 and ÖNORM B 1991‑1‑4 in the Dlubal Software online tool 'Snow, Wind, and Seismic Zone Maps' uses a planar Voronoi diagram to distribute the tabular loads by reference location to regions.
