Convert all GRASS 6 vector maps to GRASS 7
Convert automatically all GRASS 6 vector maps to GRASS 7 (including attribute transfer from DBF to SQLite)
To become usable in GRASS 7, all vector maps in a mapset need to be updated to the improved vector file format (i.e., rebuild the topology withalong with the change to the SQLite database backend (new default in GRASS 7 instead of DBF in GRASS 6, using and ).
Run this in GRASS 7:
# first rebuild topology for all vector maps v.build.all # set new default db connection (from DBF to new SQLite default) db.connect -d # copy attribute tables from old DB to new SQLite DB, delete old tables in DBF format v.db.reconnect.all -cd
Q: Can I reopen the vector maps later in GRASS GIS 6?
A: Yes, but you need to rebuild the topology. Hence, run this:
Then the vector maps of the current mapset will be readable by GRASS GIS 6 again.
