Hello,
I need to do some calculations on my attribute tables.
What is the corresponding command in GRASS for this?
v.db.addcol
v.db.update
Is it safe to edit the DBF-table outside of GRASS in another program?
For instance in OpenOfficeCalc?
Or even as a CSV with Python, IDL, etc.?
Yes. You can actually create whatever dbf you want, wherever you want as
long as it contains a column with the id's of the objects. Then you can
connnect your vector map to this dbf with v.db.connect.
