The Topological Optimization operation can be directly executed by typing the following expression on the command line of the Main window:
|
OUTMAP |
= |
MapTopologicalOptimization(drainnetwork_rasmap, flowdir_rasmap, stream_segmap, output_modified_flowdir_rasmap) |
where:
|
OUTMAP |
is the name of the output raster map that will contain an updated drainage network. |
|
MapTopologicalOptimization |
|
|
is the command to start the Topological Optimization operation. |
|
|
drainnetwork_rasmap |
is a raster map that is the outcome of a previous Drainage Network Extraction operation, i.e. a raster map with a Bool domain. |
|
flowdir_rasmap |
is a raster that is the outcome of a previous Flow Direction operation, i.e. a raster map with system domain FlowDirection. |
|
stream_segmap |
is a segment map containing straight lines between inlets and outlets, e.g. in lakes. |
|
output_modified_flowdir_rasmap |
is the name of an updated output flow direction raster map that will contain improved flow directions. |
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.
