Start and Discrete Preference Map

1. Discrete Map – identifies the relative preference for locating a route at any location (1= Good through 9= bad) Discrete Map Good Easy Favor Bad Difficult Avoid Start and Discrete Preference Map Start – identifies the beginning of the route as an existing transmission line in this case Accumulation Surface

2. X = …the Geometric Distance of is multiplied by the Discrete Cost for each potential step to determine the Effective Distance at each wave front increment. The optimal movement is the lowest accumulated effective distance value. Accumulation Surface (0 TO 1) Accumulation Surface – identifies the “total cost” for locating the preferred route from the starting location to everywhere in a project area Discrete Map Good Easy Favor Bad Difficult Avoid Accumulation Surface

24. 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) Discrete Map Accumulation Surface
