Google today unveiled Google Earth 4 - and it's not beta anymore. The major new feature in this version is the support for textured 3D buildings and new higher-quality terrain data for mountainous regions.
You can download it at Google's website.
Here are two stunning pictures:
The first image is Uluru (Ayers Rock) in Australia and the second picture is the Colosseum in Rome.
Pretty cool Google but I'm still waiting for higher quality imagery of my area
Except a small piece my province (East-Flanders) is still extremely blurry. Some high-res imagery like in Brussels or The Netherlands would make me happy Google
