The Overland Flow Length operation can be directly executed by typing the following expression on the command line of the Main window:
|
OUTMAP |
= |
MapOverlandFlowLength(drainorder_rasmap, flowdir_rasmap) |
where:
|
OUTMAP |
is the name of the output raster map that will contain the overland distance towards the nearest drainage. |
|
MapOverlandFlowLength |
|
|
is the command to start the Overland Flow Length operation. |
|
|
drainorder_rasmap |
is a raster map that is the outcome of the Drainage Network Ordering operation, i.e. a raster map with an Identifier domain. |
|
flowdir_rasmap |
is a raster that is the outcome of the Flow Direction operation, i.e. a raster map with system domain FlowDirection. |
When the definition symbol = is used, a dependent output map is created; when the assignment symbol := is used, the dependency link is immediately broken after the output map has been calculated.
