DESCRIPTION

66       r.plane creates a tilted plane raster map given user-specified  parame‐
67       ters  for  inclination, azimuth, and the geographic location of a point
68       on the plane.
69       The angle orientations of the azimuth parameter increase counter-clock‐
70       wise, i.e., 0 degree = N, 45 degree = NW, 90 degree = W etc.
71
72       Increasing values of the dip parameter progressively lower (or dip) the
73       northern half of the plane, and incline the southern half, assuming the
74       azimuth parameter is held constant at 0 degrees.
75

NOTES

77       g.region  -c provides the easting and northing coordinates for the cen‐
78       ter of the current region.
79
80       CELL (integer) maps take less disk space than FCELLs (floating  point),
81       which in turn take up less space than DCELLs (double precision floating
82       point).

EXAMPLE

85       A tilted plane in the North Carolina sample dataset region:
86       # set computational region
87       g.region raster=elev_lid792_1m -p
88       # get center coordinates as an example
89       g.region -c
90       # get terrain height at point
91       r.what map=elev_lid792_1m coordinates=638650.0,220375.0
92       # shows elevation: 116.7734
93       # generate tilted plane
94       r.plane myplane30 dip=30 az=75 east=638650.0 north=220375.0 \
95               elev=116.7734 type=FCELL
