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
Type of raster map to be created
Storage type for resultant raster map
Options: CELL, FCELL, DCELL
Default: FCELL
CELL: Integer

DCELL: Double precision floating point
DESCRIPTION
r.plane creates a tilted plane raster map given user-specified parame-
ters for inclination, azimuth, and the geographic location of a point
on the plane.
The angle orientations of the azimuth parameter increase counter-clock-
wise, 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 cen-
ter of the current region.
CELL (integer) maps take less disk space than FCELLs (floating point),
which in turn take up less space than DCELLs (double precision floating
point).
EXAMPLE
A tilted plane in the North Carolina sample dataset region:
# set computational region
g.region raster=elev_lid792_1m -p
# get center coordinates as an example
g.region -c
# get terrain height at point
r.what map=elev_lid792_1m coordinates=638650.0,220375.0
# shows elevation: 116.7734
# generate tilted plane
r.plane myplane30 dip=30 az=75 east=638650.0 north=220375.0 \
elev=116.7734 type=FCELL
