org.n52.wps.ags.spatialanalyst.distance.costpath CostPath_sa Calculates the least-cost path from a source to a destination. Uses ArcObjects library - Spatial Analyst in_destination_data in destination data A raster or feature dataset that identifies those cells from which the least-cost path is determined to the least costly source. If the input is a raster, the input consists of cells that have valid values (zero is a valid value), and the remaining cells must be assigned NoData. application/x-zipped-shape application/x-zipped-shape destination_field destination field The field used to obtain values for the destination locations. Input feature data must contain at least one valid field. in_cost_distance_raster in cost distance raster The name of a cost distance raster used to determine the least-cost path from the in_destination_data cell locations to a source. The in_cost_distance_raster is usually created with the CostDistance function (or by the CostAllocation or CostBackLink functions). The in_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. application/img application/GeoTIFF application/img in cost backlink raster in cost backlink raster The name of a cost backlink raster used to determine the path to return to a source via the least-cost path. For each cell in the backlink raster, a value identifies the neighbor that is the next cell on the least accumulative cost path from the cell to a single source cell or set of source cells. application/img application/GeoTIFF application/img path_type path type A keyword defining the manner in which the values and zones on the in_destination_data will be interpreted in the cost path calculations. EACH_CELL — For each cell with valid values on the in_destination_data, a least-cost path is determined and saved on the output raster of the CostPath function. With EACH_CELL, each cell of the in_destination_data input is treated separately, and a least-cost path is determined for each from cell. EACH_ZONE — For each zone on the in_destination_data , a least-cost path is determined and saved on the output raster of the CostPath function. With the EACH_ZONE keyword, the least-cost path for each zone begins at the cell with the lowest cost distance weighting in the zone. BEST_SINGLE — For all cells on the in_destination_data input, the least-cost path is derived from the cell with the minimum of the least-cost paths to source cells. EACH_CELL EACH_ZONE BEST_SINGLE
