That is a very useful resource; thank you.

Some cities make shapefiles available for urban growth boundaries and city limits. It's worth enquiring. But be aware that some cities city limits are not simple polygons; depending on local ordinances you can see islands, internal voids and peninsulas attached with zero width stems.

True! Like Houston, TX ... which looks a little like the flying spaghetti monster ... http://nominatim.openstreetmap.org/details.php?place_id=3675...

The poly files that you get from the process outlined in the readme file will include islands/voids. It's pretty cool.
