Statements that we should fix all the unedited TIGER data express a Great Idea. They are, however, rather ambitious statements, and will require more than a few weeks to completely realize. As such, cleaning up US TIGER data is a Long Term goal, and does not say anything regarding how we might prioritize and coordinate work to realize this goal.<div>
<br></div><div>Given the size of the effort, it's crucial that work is organized in smaller, more bite-sized pieces, so that we can all celebrate the completion every few weeks of a portion of the work.</div><div><br>
</div><div>Here are some suggestions:</div><div><br></div><div>Order US counties by population, largest first, review primary, secondary and tertiary ways (NE2 and other have been systematically reviewing interstates and other number routes over the last few months), compare with TIGER 2012, correct way attributes, and register road geometry to aerial photography</div>
<div><br></div><div>or</div><div><br></div><div>Order US counties by population, largest first, and review all ways (in way class order) that have not been edited in the last six months, compare with TIGER 2012, correct way attributes, and register road geometry to aerial photography</div>
<div><br></div><div>or ....</div><div><br></div><div>I will also point out that the connectivity errors I mentioned earlier are, in fact, largely a result of unedited TIGER data (see <a href="http://wiki.openstreetmap.org/wiki/TIGER_fixup">http://wiki.openstreetmap.org/wiki/TIGER_fixup</a>, for example) and do present a well defined subset of issues to focus upon. A secondary, and perhaps less obvious, benefit of addressing road network connectivity issues is the significant increase in quality of routes generated by tools such as OSRM (<a href="http://project-osrm.org/">http://project-osrm.org/</a>). There exists significant interest on OSM as a data source for routing and navigation applications (<a href="http://www.slideshare.net/dnesbitt61/sotm-us-routing">http://www.slideshare.net/dnesbitt61/sotm-us-routing</a>, and others), and showing progress in this area could be a large boost to the rate of OSM adoption.</div>
<div><br></div><div>In any case, it's important to come to agreement on a set of constrained, well defined short term goals that demonstrate steady progress to help keep everyone engaged and motivated.</div><div><br></div>

<u></u> <u></u>I also
think it would be great, if we could focus on unedited TIGER. That would
clean up the map a lot. There may be some technical challenges, but
overal it would be a good thing.<br>
<u></u> <u></u>I know
someone suggested roads without a name, though I think there was
discussion that would be technically difficult and also might produce a
lot of focus on country roads and tracks that never have had a name.
However, if we limit it to roads changed by the redaction, that might be
one way to restore the names from TIGER that were lost.<br>
<u></u> <u></u>Some
things I would like to see in the future include editing all the national
parks. I know that there is data on their Web sites, which, I think, is
all public domain. That would be a good thing to do.<br><br>
Best,<br><br>

These can easily be identified simply as those ways that have a name but
are still the original Tiger data and have not been edited. (except for
the balrog-kun bot). You could just identify spots not closer together
than (say) 1 mile and that would allow the editor to have a nice piece of
real estate to clean up each time.<br>
It is quite fun doing this since (with the help of TIGER 2012) overlay
and Bing imagery, it is usually possible to determine which road goes
where and you see an enormous improvement in the map for relatively small
efforts.<br>
<br>
If the remap-a-tron identifies an area where all the original; TIGER data
was correct, then no problems, we just flag it as good and move on, but
at least that area has now been eyeballed by a real person who probably
will be able to add in a few new TIGER 2012 roads if they have the
overlay active.<br>
