More work on the body of Stanford campus.

Wish I had an iPhone app to help store pictures alongside with GPS traces.

(Dunno if that'd be useful for getting buildings right given the (lack of) accuracy on the device.)

That said, it'd be a great way to gather data more conveniently on a larger scale, to have a GPS trace where points (segments?) can be tagged with pictures, sounds, actual tags, or text!

Also getting up to speed on the OSM XML format. Seems challenging to deal with -- is it a bear to get imported into PostGIS? Might try to extract just enough data using XQilla...
