Google Fusion Tables16 Sep 2011
Thanks to Hilary Parker for pointing out Google Fusion Tables. The coolest thing here, from my self-centered spatial statistics point of view, is that it automatically geocodes locations for you. So you can upload a spreadsheet of addresses and it will map them for you on Google Maps.
Unfortunately, there doesn’t seem to be an easy way to extract the latitude/longitude values, but I’m hoping that’s just a quick hack away….
