OutletIds: Find Outlet IDs

In rcapell/RHYPE: Tools for Processing and Analyzing Files from the Hydrological Catchment Model HYPE

Find Outlet IDs

Description

Function to find the identifier(s) used to signify model domain outlets, i.e. the "downstream" ID of outlet catchments, in a GeoData file. This is typically just one number, often e.g. '0' or '-9999', but can be one or several IDs if the GeoData file originates from a HYPE sub-model set-up, e.g. created with the 'SelectAro' program. Use OutletSubids to find the actual SUBID values of the outlet catchments.

Usage

OutletIds(gd)

Arguments

gd	Data frame with two columns subid and maindown (not case-sensitive). Typically a 'GeoData.txt' file imported using ReadGeoData.

Details

OutletIds finds the unique outlet IDs of a GeoData file. The outlet ID of a typical model is a single placeholder number, often e.g. '0' or '-9999', but there can be several outlet IDs, e.g. one or several SUBIDs if the GeoData file originates from a HYPE sub-model set-up, created with the 'SelectAro' tool.

Value

OutletIds returns a vector of outlet IDs.
