  "description": "The Least Cost Path function calculates the least-cost path from a source to a destination. The least accumulative cost distance is calculated for each pixel over a cost surface, to the nearest source. This produces an output raster that records the least-cost path, or paths, from selected locations to the closest source pixels defined within the accumulative cost surface, in terms of cost distance.<div><br />Each least-cost path is assigned a value when encountered in the scanning process. The ending pixel on the Source Raster of a cost path receives a value of 1. The first path receives a value of 3, the second 4, and so on. When multiple paths merge and follow the remaining distance back to a source on the same route, the segment where the two paths travel together is assigned a value of 2. The merged portion of the path cannot be assigned the value of one of the paths, since the merged portion belongs to both routes.<\/div>",
