FindDownstreamBasins: Find Downstream Basins
In ECCC-MSC/Basin-Delineation: Finds upstream area and upstream stations
Description
Usage
Arguments
Value
Description
Uses the HydroBasins "NEXT_DOWN" field to identify all downstream
polygons from a target polygon. It is possible to stop downstream navigation
at endorheic sinks (terminal polygons within inland basins), or to continue
through 'virtual' connections (see HydroBASINS technical documentation for
more details).
Usage
1
FindDownstreamBasins(HYBAS, HYBAS.ID, n_iter = -1, ignore.endo = T)
Arguments
HYBAS
a HYBAS spatial polygon object or dataframe from such an object
HYBAS.ID
character vector of one or more HydroBASINS ID's
n_iter
integer, how many iterations to perform. To remove limit,
set to -1 (default)
ignore.endo
logical, whether or not to include 'virtual' connections
from endorheic sinks (see HydroBASINS technical documentation for more details)
Value
a character vector of HydroBASIN ID's corresponding to downstream
basins
