rsaga.sink.removal: 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", ...)

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.

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
