Accumulation Surface (Bowl Shape)
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)
