NAME
d.grid - Overlays a user-specified grid
in the active display frame on the graphics monitor.
(GRASS Display Program)
SYNOPSIS
d.grid
d.grid help
d.grid [-g] [-b] size=value
[color=name]
[origin=easting,northing]
DESCRIPTION
d.grid overlays a grid of user-defined size and
color in the active display frame on the graphics monitor.
The grid will overlay, not overwrite, the contents of the
active display frame.
d.grid can be run non-interactively or
interactively. If the user specifies the grid
size and (optionally) the grid color on
the command line the program will run non-interactively; if
no grid color is given the default will be used.
Alternately, the user may simply type d.grid on the
command line; in this case, the program will prompt the
user for parameter values using the standard GRASS user
interface described in the manual entry for
parser.
Flags:
- -g
- Disable grid drawing
- -b
- Disable border drawing
Parameters:
- size=value
- Size of grid to be drawn in the active display frame,
in current map coordinate system units.
It should be noted that, depending on the scale of the map layer
displayed in this frame, the grid may fall outside the user's
viewing range.
Options: 0-100000
- color=name
- Sets the current grid color to name.
Options: red, orange, yellow, green, blue,
indigo, violet, magenta, brown,
gray, white, and black.
Default: gray
- origin=easting,northing
- Lines of the grid pass through this coordinate.
The coordinate need not be
within the current frame.
NOTES
d.grid will not erase grids already displayed in
the active graphics display frame by previous invocations
of d.grid; multiple invocations of d.grid
will therefore result in the drawing of multiple grids
inside the active graphics frame. (A command like
d.erase, which erases the
entire contents of the active display frame, must be run to
erase previously drawn grids from the display frame.)
Currently, the grid size can only be drawn in the units of
the map coordinate system used by the current GRASS
location.
