I'd prefer that people preserve the TIGER data whenever possible. It's not a primary concern and don't let it slow down your mapping, but it is a useful data point. Let's say we're doing a future TIGER import. Updated roads will have the same TLID between different TIGER revisions and that gives us a good starting point. It's a third bit of data to augment any matching decisions we make based on location and name. We can get along without it, but it *IS* useful. Way history is fine as a backup, but tracing that through splits and joins is not going to be easy. It's much more straightforward to just get it directly. -- Dave _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
