[GRASS-user] How to extract z-coordiante and write it into attribute table?

[Vincent Bain]

If your map is a 3d vector, v.db.connect will do the job.
First create 3 new numeric fields in the table (x,y,z), run v.db.connect
with the coord option : it will feed these attributes. 
Then you can drop x,y columns if you don't need them anymore.
