“produced by the University of Virginia’s Institute for Advanced Technology in the Humanities (IATH) and based on its Rome Reborn model, contains over 6,700 3D buildings and 250 Google Earth placemarks that allow Google Earth users to explore and learn about this fascinating period of history.”
Google says this is the first time they have incorporated an ancient city in Google Earth, hopefully we will get more of these kind of cool projects which allows us to see the ancient cities in 3D.
This layer was pushed initially by Google but looks like they have pulled it back, origiral Google blog post updated with a quote
Update @ 12:15 PM: Rome wasn’t built in a day! The Ancient Rome 3D layer will be available soon. We’re sorry for the delay, and we’ll post here when it’s live.
I can see the Ancient Rome 3D layer in my Google Earth but when i click it is showing the present Rome. See my Rome photo set at Flickr
