avoid conditions) on the Discrete Preference Map

Accumulation Surface (Bowl Shape)

Accumulation Surface

…while the Accumulation Surface looks like a terrain surface, it always forms a “bowl shape” with the lowest values around the Starting location that progressively increase as the wave front moves

away

….the value at every location on the surface indicates how “far away” the location considering the “relative goodness” for siting a route at any location in the project area (1= Good through 9= Bad)
