Hello,
I'm new to grass and gis in general and for a start I need it for a specific
purpose. I want to create simple thematic maps. Values assigned to counties
should be used to create chloropleth and proportional symbols maps. Is there a
way to do this in grass? Thanks,
Chris
Chris,
please check
http://grass.osgeo.org/grass63/manuals/html63_user/d.vect.chart.html
http://grass.osgeo.org/grass63/manuals/html63_user/d.vect.thematic.html
for your purposes.
There are currently efforts ongoing to improve d.vect.thematic.

Thanks again Markus.
I've found
http://www.nabble.com/C-replacement-for-d.vect.thematic-td14538919.html this
link
and it does definitely sound promising.

If you can (need to compile yourself), please try the already existing modules (d.thematic.area + v.class) in their current state and give me feedback. Now's the time to influence its future state.

Wow, great job! Thanks!
At first glance I'd say d.thematic.area provides everything that's needed
from a functional point of view.
no limits for class and color - that's heaven ;-), the color managment for
d.vect.thematic was too limiting.
v.class is also great. The only thing I'm not sure about is the class
algorithms. All I know about classification is from Dent, Slocum etc 
so
I could only list the classifications they suggest. Need to check on
"equiprobable". The more the better, but I guess they can still be
implemented later without much hassle(?).
From the point of view of userfriendliness (if that is an aim of grass
some help on colors would be great, but not necessary.
Just don't drop the current possibility of manual color and class input.
As I'm new to the whole subject I probably won't be of much help to you, but
I definitely like what you've done with v.class and d.thematic.area.
Symbols, Proportional Symbols (with custom symbols, perceptual and maths
scaling, orientation), cartograms (eg Dorling's algorithm) and other types
of maps would of course be a great enhancement to grass' thematic mapping
capabilities, hehe ^ ^
but again, great job on the two new classes, you made my day
