Areas of Influence

Generates polygons representing areas of influence around selected points based on proximity. These polygons, known as Voronoi diagrams, define regions closest to each point in the selection.

Each resulting polygon inherits the attribute data of its corresponding point.

This functionality is useful for spatial analysis tasks such as identifying coverage zones for pharmacies within a municipality or similar proximity-based studies.
