Thiessen Polygons

Thiessen polygons, also known as Voronoi diagrams, are a way to divide a region into areas around a set of specific points, such as weather stations or service centers. Each polygon contains all locations closer to its corresponding point than to any other point. This method helps in assigning data or resources based on proximity, ensuring each area is associated with the nearest point, making it useful in spatial analysis and resource distribution. In essence, Thiessen polygons create natural boundaries around points, representing influence zones based purely on distance.
