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).
