GRASS GIS manual: r.plane

NAME

r.plane - Creates raster plane map given dip (inclination), aspect (azimuth) and one point.

KEYWORDS

raster, elevation

SYNOPSIS

r.plane
r.plane help
r.plane output=name dip=float azimuth=float easting=float northing=float elevation=float type=string [--overwrite] [--verbose] [--quiet]

Flags:

--overwrite: Allow output files to overwrite existing files
--verbose: Verbose module output
--quiet: Quiet module output

Parameters:

output=name [required]: Name for output raster map
dip=float [required]: Dip of plane in degrees; Default: 0.0
azimuth=float [required]: Azimuth of the plane in degrees; Default: 0.0
easting=float [required]: Easting coordinate of a point on the plane
northing=float [required]: Northing coordinate of a point on the plane
elevation=float [required]: Elevation coordinate of a point on the plane
type=string [required]: Type of the raster map to be created; Options: int, float, double

DESCRIPTION

r.plane creates a tilted plane raster map given user-specified parameters for inclination, azimuth, and the geographic location of a point on the plane.
The angle orientations of the azimuth parameter increase counter-clockwise, i.e., 0 degree = N, 45 degree = NW, 90 degree = W etc.

Increasing values of the dip parameter progressively lower (or dip) the northern half of the plane, and incline the southern half, assuming the azimuth parameter is held constant at 0 degrees.

NOTES

g.region -c provides the easting and northing coordinates for the center of the current region.

int maps take less disk space than floats, which in turn take up less space than doubles (but can be less exact).

EXAMPLE

A tilted plane in the North Carolina sample dataset region:

g.region -d
g.region -c
r.plane myplane45 dip=45 az=90 east=527500.0 north=165000.0 \
        elev=1000 type=float
