<html><P>Yeah, I knew trying to do sequential pulls would create a number of coordination issues, I just didn't know what the plan was. I figured someone smarter than me had figured out a cool way to do it, like keying on the tiger_reviewed tag and automatically replacing centerline data that hadn't been reviewed with the revised entity in TIGER. Things could still get messy where a user has added new subdivisions & features before the TIGER data release with the "official" position data for those streets. You'd need some sort of way to flag street centerlines that are too close to be reasonable, or cross, or whatever, and somehow keep it from flagging every divided highway in the system. Doesn't sound fun.</P>
<P>The idea of creating tools for users to pull thier county of interest and compare the new TIGER with OSM might be useful. I thought I saw where Steve C had done a comparison of OSM's centerline info with Google/NAVTEQ's info for an area of interest in an automated way (although I could certainly be mistaken on that point). A highlight tool for OSM vs. new TIGER for a county sized region with arial imagery in the background would be an awesome tool to rapidly scan for things that may have been missed...or areas where TIGER is really out of the loop :-)</P>
<P>All in all I'm in awe of the data conversion process that has already taken place. I've been playing around with the streets in my city (Stockton, CA) and I can't imagine having a situation similar to the UK where every single street had to be loaded by hand from scratch! Thanks Dave for the great work!</P>

<DIV dir=ltr>Another alternative may be to be for the people working in an area they care about to do those steps manually. I'm very interested in the Seattle data because the TIGER data that's there now has some definite gaps. :)<BR><BR><BR>Beau<BR><BR>
