Label | Explanation | Data Type |
Input accumulative cost distance raster 1 | The input raster representing the accumulative cost distance from the first source. Use the distance accumulation output from the Distance Accumulation or Distance Allocation tool. | Raster Layer |
Input back direction raster 1 | The input back direction raster from the first source. The units are degrees identifying the next cell along the least-cost path back to the first source. Use the back direction output from the Distance Accumulation or Distance Allocation tool. The range of values is from 0 degrees to 360 degrees, with 0 reserved for the source cells. Due east (right) is 90, and the values increase clockwise (180 is south, 270 is west, and 360 is north). | Raster Layer |
Input accumulative cost distance raster 2 | The input raster representing the accumulative cost distance from the second source. Use the distance accumulation output from the Distance Accumulation or Distance Allocation tool. | Raster Layer |
Input back direction raster 2 | The input back direction raster from the second source. The units are degrees identifying the next cell along the least-cost path back to the second source. Use the back direction output from the Distance Accumulation or Distance Allocation tool. The range of values is from 0 degrees to 360 degrees, with 0 reserved for the source cells. Due east (right) is 90, and the values increase clockwise (180 is south, 270 is west, and 360 is north). | Raster Layer |
Threshold method | Specifies how the threshold will be defined.
| String |
Threshold | A percent or accumulative cost threshold that determines whether a given cell will be included in the output corridor raster. When the Threshold method parameter is set to Percent of least cost, the specified value indicates the percent increase to apply from the minimum value of the summed accumulative cost distance rasters. When the Threshold method parameter is set to Accumulative cost, the value indicates cells that have a summed accumulative cost equal to or below the value will be included in the corridor. This parameter is only active if the Threshold method parameter is set to Percent of least cost or Accumulative cost. | Double |
Return Value
Label | Explanation | Data Type | Output raster | The output corridor raster containing cells with values below the threshold in accumulative cost distance units. The output raster is floating-point type. | Raster |
