DESCRIPTION

104       d.grid overlays a grid of user-defined size and  color  in  the  active
105       display  frame  on  the graphics monitor.  The grid can be created as a
106       standard rectangular grid or a geographic grid.
107
108       If the user provides a -g flag a geographic (projected)  grid  will  be
109       drawn.  With the -g flag the size argument accepts both decimal degrees
110       and colon separated ddd:mm:ss coordinates (eg. 00:30:00 for half  of  a
111       degree).  A geographic grid cannot be drawn for a latitude/longitude or
112       XY projection.
113
114       Colors may be standard named GRASS colors (red, green, aqua, etc.) or a
115       numerical R:G:B triplet, where component values range from 0-255.  Grid
116       color can be set with option color. Options text_color and bgcolor  set
117       the color of the text and its background.
118
119       The grid drawing may be turned off by using the -n flag.
120       The border drawing may be turned off by using the -b flag.
121       The coordinate text may be turned off by using the -t flag.
122
123       To  draw grid lines at different intervals, e.g. at high latitudes, you
124       can run the module twice, once with direction=east-west at one interval
125       size, and again with direction=north-south at another interval size.

EXAMPLES

128       To  draw  a red geographic grid with 30 minute grid spacing, run one of
129       the following commands:
130       d.grid -g size=00:30:00 color=red
131       or
132       d.grid -g size=0.5 color=255:0:0
133       Figure: Showing a geographic grid in red line  color  To  draw  a  blue
134       standard rectangular grid at a 500 (meter) spacing run the following:
135       d.grid size=500 color=blue
136       Figure: Showing a rectangular grid in blue line color
