Earlier this week we had a look at how long it takes Google to process and release 3D imagery. For a few locations, we looked at the dates the imagery was captured as well as the dates that it was first discovered in Google Earth.
Now, GEB reader Anton Rudolfsson, who has been assisting us by delineating newly found 3D areas for our KML map, has also taken the trouble of tracking down the dates for the various 3D releases and categorizing all the areas by release date. So as of today, our KML file includes the option to see the areas either categorized by country or by date discovered.
There are three regions that Anton was unable to track down the dates for: Hollister, El Centro and Truckee, all in California. So if any of our readers know approximately when these were first spotted in Google Earth, please let us know in the comments.
Colour coded regions by date discovered – Europe. White is oldest, Red is newest.
Colour coded regions by date discovered – North America. White is oldest, Red is newest.
