rsaga.sink.route: Sink Drainage Route Detection

In RSAGA: SAGA Geoprocessing and Terrain Analysis

Sink Drainage Route Detection

Description

Sink drainage route detection.

Usage

rsaga.sink.route(in.dem, out.sinkroute, threshold, thrsheight = 100, ...)

Arguments

in.dem	input: digital elevation model (DEM) as SAGA grid file (default file extension: .sgrd)
out.sinkroute	output: sink route grid file: non-sinks obtain a value of 0, sinks are assigned an integer between 0 and 8 indicating the direction to which flow from this sink should be routed
threshold	logical: use a threshold value?
thrsheight	numeric: threshold value (default: 100)
...	optional arguments to be passed to rsaga.geoprocessor(), including the env RSAGA geoprocessing environment

Value

The type of object returned depends on the intern argument passed to the rsaga.geoprocessor(). For intern=FALSE it is a numerical error code (0: success), or otherwise (default) a character vector with the module's console output.

Note

I assume that flow directions are coded as 0 = north, 1 = northeast, 2 = east, ..., 7 = northwest, as in rsaga.fill.sinks().
