Remarks
|
sourcePoints |
input collection of points which identifies the destinations in which the least cost path is routed to |
|
distance |
the name of a cost distance Raster to be used to determine the least cost path from the fromRaster cell locations to a source. The distance Raster is usually created with the IDistanceOp::CostDistance method (or by the IDistanceOp::CostDistanceFull method). The distance Raster stores, for each cell, the minimum accumulative cost distance over a cost surface from each cell to a set of source cells. |
|
backlink |
the name of a cost back link Raster used to determine the path to return to a source via the least-cost path For each cell in the back link raster, a value identifies the neighbor that is the next cell on the least accumulative cost path from the cell to a single or set of source cells. |
- The method returns a reference to a Polyline object.
