In RSAGA: SAGA Geoprocessing and Terrain Analysis

Contour Lines from a Grid

Description

Creates a contour lines shapefile from a grid file in SAGA grid format.

Usage

rsaga.contour(
  in.grid,
  out.shapefile,
  zstep,
  zmin,
  zmax,
  vertex = "xy",
  env = rsaga.env(),
  ...
)

Arguments

in.grid	input: digital elevation model (DEM) as SAGA grid file (default file extension: .sgrd)
out.shapefile	output: contour line shapefile. Existing files will be overwritten!
zstep, zmin, zmax	lower limit, upper limit, and equidistance of contour lines
vertex	optional parameter: vertex type for resulting contours. Default "xy" (or 0). Only available with SAGA GIS 2.1.3+. 0 "xy" 1 "xyz"
env	A SAGA geoprocessing environment, see rsaga.env()
...	arguments to be passed to rsaga.geoprocessor()

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 (the default) a character vector with the module's console output.
