Sry for that. I will try it again. A basis I have a .csv-file including LIDAR points. I imported that csv-file via v.in.ascii into location A. Because I need this data in another projection, I created a location B and used v.proj to reproject the point cloud from location A to location B. Now I would need the z-coordinate as attribute to it´s corresponding point. As you recommended I tried to add the tables (v.db.addcol) and this worked. Then I wanted to fill the columns using v.to.db. But this didn´t work. Then I deleted all the files and imported the csv-file again using the same workflow as before. Now I have the problem that there is no corresponding table in the dbf-directory and so I cannot try to add columns as before. I hope it´s all a little bit clearer.
