I actually would prefer that the tiger:* tags were removed from those nodes, since they are indeed not useful, though I suppose I could just do this myself fairly simply. >Another option would be to completely exclude every node that has been >touched after the import (i.e. operate only on those with the pristine >version number 1). That would exclude 4 million nodes from the operation >(and leave 168 million to work on).

The biggest problem with TIGER in my area is position of the nodes. I've moved thousands. I would not want them excluded (and continue to have lower performance) simply because they were moved. I vote to hit those nodes too. -- Alan Mintz <[email protected]> _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
