DESCRIPTION

67       d.rast.num overlays cell category values onto a raster map  layer  dis‐
68       played  on  the  user’s graphics monitor.  Category values will be dis‐
69       played in the text color given and scaled to fit within a single  cell.
70       A  grid  outlining each map cell will also be overlain in a user-speci‐
71       fied color, unless it has been set to "none".
72
73       If no grid color is given the default will be used. If no map layer  is
74       specified,  the program will use whatever raster map layer is currently
75       displayed in the active frame on the graphics monitor.
76
77       If the -f flag is given the displayed number will take on the color  of
78       the base map in that cell.
79

NOTES

81       The  user  is  advised  to set the current region to a relatively small
82       area (i.e., less than 100 rows by 100 columns); otherwise, the individ‐
83       ual  cells being displayed will be small and the category value associ‐
84       ated with each will be difficult to see.  No data cells  are  indicated
85       with "Null".
86

EXAMPLE

88       A) Distance from the streams network (North Carolina sample dataset):
89       g.region raster=streams_derived -p
90       r.grow.distance input=streams_derived distance=dist_from_streams
91       d.rast.num dist_from_streams -a
92       Euclidean  distance from the streams network in meters (detail, numbers
93       shown with d.rast.num)
