[GRASS-user] How choosing the colors of an imported map

Mon Aug 18 10:34:33 EDT 2008

I am doing exactly that with the following script.

v.in.ascii input=textFile output=$RasName fs='tab' x=3 y=4 skip=0 cat=1
v.surf.rst input=RasName at Temp layer=1 zcolumn=dbl_3 tension=40.
elev=$RasName2 dmax=100 dmin=1
r.colors map=RasName at Temp color=arb-precip

Of course, your parameters for the commands above would be different based
on what you are importing.

arb-precip is a custom colormap that I created and placed in
$GIDBASE/etc/colors which looks like
