Computes Strahler orders in a cell tree.
StrahlerOrdering ( handle_tree , threshold , handle_res )
integer: handle of the cell tree defining the catchment in which to compute Strahler orders.
Support area (i.e. minimal weight) defining the first-order streams.
integer: handle of the raster in which to store computed Strahler orders (this raster must have been created previously, using any of CreateFloatRaster
, CreateRasterFromBinary
, or CreateConstantRaster
)
Computes Strahler orders in a cell tree a writes the results of the computations to an existing raster.
