[GRASSLIST:3852] Re: v.to.rast

[Michael Barton]

Sabine,

You can use d.out.png to export the current display to a *.png 
file--which you then can insert into PowerPoint. This is in the 'file' 
menu in GRASS 5.3 and 5.7. If you have a 5.0.x version, you can 
download the script from the script exchange on my website and use it 
from the command line <www.public.asu.edu/~cmbarton/grass.htm

To get larger points using GRASS 5.0.x or 5.3, use the d.sites.icons 
script. Make an icon that you like using p.icons and a text editor 
(check out d.icon in the manual), then display it for your sites using 
d.sites.icons. For example the following makes a 'house' icon.
    x
  xxx
xxxxx
xxxxx
xxxxx

You can set the size and color just like in the standard sites symbols.

Hope this helps.

Michael Barton
