Dear list,
I'm using Grass 6 in the development of a cellphone network planning tool. I
would like to plan a network by setting up some cellphone towers, and would like
to know if there is some function in Grass which will enable me to place small
'tower'-icons on a raster map at specific geopoints. I am using r.what to
retrieve the location where a tower was set up, but would like to display all
the towers already set up as well.
Regards,
Kobus

Make the tower possitions as vector points (v.in.ascii) then display
with "d.vect icon=your/tower". For hard copies you've got a bit more
control with ps.map, eg you can use a EPS file for the icon and
dynamically set the size with vpoints sizecol.
You'll have to make your own tower icon of course, it's not so hard to
do:

move the file into $GISBASE/etc/symbol/local/tower or somewhere like
that.
It works really well.
Also check out "d.vect display=attr", v.label and d.paint.labels for
attaching tags.

Thanks a lot Hamish,
It works perfectly.

Thanks a lot Hamish,

great.
I should add that if you are really proud of your homebrew symbol by all
means share it with the list for others to try &/or for possible
inclusion in future releases in GRASS.
