.SH DESCRIPTION
\fIr.plane\fR creates a tilted plane raster map given user-specified
parameters for inclination, azimuth, and the geographic location of a
point on the plane.
.br
The angle orientations of the \fIazimuth\fR parameter increase counter-clockwise,
i.e., 0 degree = N, 45 degree = NW, 90 degree = W etc.
.PP
Increasing values of the \fIdip\fR parameter progressively lower (or dip) the northern
half of the plane, and incline the southern half, assuming the \fIazimuth\fR parameter 
is held constant at 0 degrees.
.SH NOTES
g.region \-c provides the easting and northing coordinates for
the center of the current region.
.PP
\fIint\fR maps take less disk space than \fIfloat\fRs, which in turn
take up less space than \fIdouble\fRs (but can be less exact).
