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

[Michal Migurski]

I pulled together some of the notes and imagery I've been posting here recently:

	http://www.openstreetmap.us/~migurski/green-means-go/

It's a map of 1km×1km squares covering the continental United States. Green squares show places where data imports are unlikely to interfere with community mapping. Raw data is linked at the bottom.

Three things that would make this better:

- Regular updates with archived older versions.
- Renders for specific counties, intended for local GIS communities.
- Some awareness of full planet history.

The OSM-US server has data for regular updates.
