Honeycombing The Icosahedron and Icosahedroning the Sphere

Abstract

This paper is an attempt to trace the theoretical foundations of the Forest Inventory and Analysis and Forest Health Monitoring hexagon networks. It is important in case one might desire to alter the intensity of the grid or lay down a new grid in Puerto Rico and the U.S. Virgin Islands, for instance. The network comes from tessellating an icosahedron with hexagons and projecting those hexagons to a sphere. The paper proposes a sample network for Puerto Rico and the U.S. Virgin Islands.
