In RSAGA: SAGA Geoprocessing and Terrain Analysis

Sink Removal Remove sinks from a digital elevation model by deepening drainage routes or filling sinks.

Description

Sink Removal Remove sinks from a digital elevation model by deepening drainage routes or filling sinks.

Usage

rsaga.sink.removal(in.dem, in.sinkroute, out.dem, method = "fill", ...)

Arguments

in.dem	input: digital elevation model (DEM) as SAGA grid file (default file extension: .sgrd)
in.sinkroute	optional input: sink route grid file
out.dem	output: modified DEM
method	character string or numeric value specifying the algorithm (partial string matching will be applied): "deepen drainage route" (or 0): reduce the elevation of pixels in order to achieve drainage out of the former sinks "fill sinks" (or 1): fill sinks until none are left
...	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

This function uses module 1 from SAGA library ta_preprocessor.
