[GRASSLIST:3805] v.to.rast

[Sabine Grabner]

hello, i need a picture of my digital elevation model with a few 
meteorological stations for a power point presentation. i thought i convert my 
vector data to raster and merge the two rasters together. 
 
but when i use v.to.rast i get only one station out of 30!? 
 
the table of the vector looks like this:  
 cat |       x       |       y        |  z   |        name          
-----+---------------+----------------+------+--------------------- 
   1 |  194197.23537 | 5191251.584895 | 1906 | Vent 
   2 | 226928.392144 | 5236860.658687 |  579 | Innsbruck-Flughafen 
   3 | 202576.650269 | 5192186.387956 | 1938 | Obergurgl 
   4 | 265000.467163 |  5225174.19567 |  643 | Mayrhofen 
  ... 
 
 
GRASS 5.7.0:~/diss/grassdata > v.to.rast in=meteostation out=meteostation 
use=... 
 
no matter which use option i take,i get only one point, which appears always 
at the same coordinates also independent of the cat i choose. 
 
using use=attr i get an error message: 
GRASS 5.7.0:~/diss/grassdata > v.to.rast in=meteostation out=meteostation 
use=attr col=name 
Loading vector information ...ERROR: Column type not supported by 
db_select_to_array() 
 
using 'z' instead of 'name' works, but i get also just one point. 
 
by the way, my point is very small, is there a possibility to make it larger? 
 
does anyone have an idea how to get my items to the power point presentation? 
 
thank you, sabine
