Table of contents


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.


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).


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
