   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
           Type of raster map to be created
           Options: CELL, FCELL, DCELL
           Default: FCELL

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.

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