Extract basins outlets locations with various approaches. These various options are mutually exclusives.

option `strahler` extract all the basins of the given strahler order

get_outlets(st, strahler = NA, large = NA, elevation = NA, gisbase = NA)

Arguments

st	A SpatRaster multi-layers object from `dem_process`
strahler	The Strahler order of the outlets to be extracted
large	The minimum size (in pixels) for the extraction of the largest possible set of basins
elevation	The elevation of the outlets
gisbase	In the case of elevation option, the directory path to GRASS binaries and libraries, containing bin and lib subdirectories among others

Value

a SpatVector with identified outlets

Details

option `large` extract the largest possible basins from the DEM. The indicated minimum size should be larger than the accumulation threshold used to delineate the network.

option `elevation` extract all outlets at a given elevation
