How does the cost path tool work in ArcGIS Pro?
The Cost Path tool determines the least-cost path from a destination point to a source. Aside from requiring that the destination be specified, the Cost Path tool uses two rasters derived from a cost distance tool: the least-cost distance raster and the back-link raster.
How does the cost path as raster tool work?
The Optimal Path As Raster tool provides enhanced functionality or performance. 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.
When to use cost path as Polyline in ArcGIS?
Cost Path as Polyline can be used to determine a path around barriers based on the Output back direction raster generated from the Euclidean tools. To use Cost Path as Polyline in this way, first run any of the Euclidean tools with Input raster or feature barrier data defined to generate the Output distance raster and Output back direction raster.
How is the cost backlink raster used in ArcGIS?
The cost backlink raster to be used to determine the path to return to a source via the least-cost path, or the shortest path. For each cell in a backlink, back direction, or flow direction raster, the value identifies the neighbor that is the next cell on the path from that cell to a source cell.
How does the cost path tool work in Excel?
The Cost Path tool determines the least-cost path from a destination point to a source. Aside from requiring that the destination be specified, the Cost Path tool uses two rasters derived from a cost distance tool: the least-cost distance raster and the back-link raster. These rasters are created from the Cost Distance or Path Distance tools.
How is the cost distance raster used in ArcGIS?
The cost distance raster is usually created with the Cost Distance, Cost Allocation or Cost Back Link tools. The cost distance raster stores, for each cell, the minimum accumulative cost distance over a cost surface from each cell to a set of source cells.
How is the path of Least Resistance used in ArcGIS?
Cost Path can also be used to derive the path of least resistance down a digital elevation model (DEM). In this case, use the DEM for the Input cost distance raster and the output from the Flow Direction tool for the Input cost backlink raster.
