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 Spearfish region:
r.plane myplane45 dip=45 az=90 east=599490 north=4920855 \
elev=1000 type=float
