[Talk-us] More on TIGER: Where it's likely safe to import

[Michal Migurski]

Agreed. What I *really* want is a version of this map that's tailored to meaningful jurisdictions, Census places and counties. It's one thing to see an all-over view but if you're a city GIS guy and you have a file of data that you want to input, it'd be useful for you to see just your specific area with some guidance on how to proceed:

1. How much is green vs. not green, and the likelihood of improvement.
2. OSM users who are responsible for existing work in your area.
3. Non-highway data in the area, e.g. POIs and such.

Christine White from Esri, who attended SOTM-US in Portland, told me that at the annual user conference she gets a regular stream of these people approaching her with blobs of official data, a desire to donate it to OSM, and no knowledge about how to proceed or what effect it would have. We should help her and them!

We could give people examples of what to look for to see if the area really is a TIGER "desert," and what to check before making a move.

Then, the square kilometers could be presented in a Maproulette kind of format, but with a chance to choose which one you take on. That way, you could choose square kilometers that are near where you are working anyway or near areas with which you are familiar.
