![]() Cells that have NoData values are not included in the source set. ![]() When the input destination data is a raster, the set of destination cells consists of all cells in the input raster or feature destination data that have valid values. The value two is reserved for the merged portion of paths that have portions of a common cost path. The ending cell on the original source raster (from which the cost distance and back link were derived) of a cost path receives one, the first path receives three, the second four, and so on. These are mandatory input rasters to Cost Path.Įach least-cost path is assigned a value when encountered in the scanning process. ![]() One or more of the weighted cost tools ( Cost Distance, Cost Back Link, or Cost Allocation) are generally required to run prior to running Cost Path to create the input cost distance and back link rasters. The Cost Path tool produces an output raster that records the least-cost path or paths from selected locations to the closest source cell defined within the accumulative cost surface, in terms of cost distance. ![]() Learn more about creating the least cost path Usage Calculates the least-cost path from a source to a destination.
