[GRASS-user] ps.map rotation of symbols based upon DB column

[Willem van Mierlo]

Hi,

I would like to make a geological map, with strike-dip symbols 
(orientation of planes). I was wondering whether is was possible to 
rotate point symbols (using vpoints) based upon a db-column (like the 
size - sizecol option for vpoints), since a map generally contains a lot 
of strike-dip symbols and entering every position and orientation of 
each symbol by hand is rather tedious?

Regards,
