definitely something which should be continued. but it's not trivial.<br>some considerations <br><br>- 2009 update for tiger date should come soon. and hopefully it has less errors. makes sense to wait for it<br>- in areas where data hasn't been touched it's also very likely the areas which are of bad tiger data. adding more broken data doesn't help osm at all.<br>
- areas which haven't been touched are most likely areas no one is interested in. why clutter the database with more broken data.<br>- how do you check that tiger data was not changed? You can't take the version of a way and assume there was no change in geometry there is an ongoing discussion about deep history and this is a non trivial problem. since all tiger nodes are cleaned of their obsolete tags any tiger node will be pushed to version 2 or more. You can not rely on version number. you must verify the position itself against an old history dump.<br>
- more and more counties make their data available for the public. I hope such data is authoritative and much more useful. wherever possible this should be used instead.<br><br><div class="gmail_quote">On Thu, Sep 17, 2009 at 10:52 AM, Jim Brown <span dir="ltr"><<a href="mailto:jim@cloudmade.com">jim@cloudmade.com</a>></span> wrote:<br>

<p>Theodore,</p>
<p> </p>
<p>I’ve been looking at the work you did in Atlanta with
addressing based on Tiger 2008 and I think it looks really interesting. Nice
work.</p>
<p> </p>
<p>I’d like to see if we can help you with this, if you
want to continue with it, either by collaboration or whatever else makes sense.</p>
<p> </p>
<p>Our thinking at the moment is that it makes a lot of sense
to take the tiger addressing information in for places where the tiger data has
not been edited yet – so the road geometery matches. This looks
like about 90% of the road network at present.</p>
<p> </p>
<p>What do you think about this?</p>
