DESCRIPTION
d.rast.num overlays cell category values onto a raster map layer dis-
played on the user’s graphics monitor. Category values will be dis-
played in the text color given and scaled to fit within a single cell.
A grid outlining each map cell will also be overlain in a user-speci-
fied color, unless it has been set to "none".
If no grid color is given the default will be used. If no map layer is
specified, the program will use whatever raster map layer is currently
displayed in the active frame on the graphics monitor.
If the -f flag is given the displayed number will take on the color of
the base map in that cell.
NOTES
The user is advised to set the current region to a relatively small
area (i.e., less than 100 rows by 100 columns); otherwise, the individ-
ual cells being displayed will be small and the category value associ-
ated with each will be difficult to see. No data cells are indicated
with "Null".
EXAMPLE
A) Distance from the streams network (North Carolina sample dataset):
g.region raster=streams_derived -p
r.grow.distance input=streams_derived distance=dist_from_streams
d.rast.num dist_from_streams -a
Euclidean distance from the streams network in meters (detail, numbers
shown with d.rast.num)
