# StrahlerOrdering

Computes Strahler orders in a cell tree.

### Calling Sequence

    StrahlerOrdering ( handle_tree , threshold , handle_res )

### Arguments

handle_tree

  integer: handle of the cell tree defining the catchment in which to compute Strahler orders.

threshold

  Support area (i.e. minimal weight) defining the first-order streams.

handle_res

  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`)

### Description

Computes Strahler orders in a cell tree a writes the results of the computations to an existing raster.
