[Talk-us] identifying TIGER deserts

[dies38061 at mypacks.net]

I know that the TIGER 2012 overlay available in JOSM has been very helpful and I think that a combination of a) increasing awareness of this overlay and b) making the overlay available in Potlatch would go a long way toward leveraging TIGER 2012.  In general, I think it is not the geometry which is most impactful, but the increase in names and the decrease in spurious or spuriously connected ways that has the most impact. --ceyockey

Any particular thoughts on what kind of processing?
What about rasterizing the most prominent "color" (i.e. missing 2012 or 2007 changes) in a 1km² area and boiling it up like Mike's Green Means Go map?
