This collection made it into the GEC layer in Google Earth on about 7 April. Since then I've received a ten-fold increase in location corrections. I have updated the collection at the top with a total of 60 community-contributed corrections. I have also repeated the geocoding using what seems to be an updated API.

The NPI released the 2006-2007 data on 31 March. Stay tuned for an update to the latest data. Now updated.

The NPI is holding a conference on 22-23 May at which I'll be presenting on what I've done with their data.
