3D Buildings with Textures in Google Earth

3D Berkeley with Textures in Google EarthOne aspect to enhancing the experience in Google Earth is the element of 3D for the terrain. I'm still surprised how many people don't realize you can pan/tilt your view in hilly areas and, if you have the "Terrain" layer turned on, you can see the hills, valleys, and mountains you might expect in Google Earth. And, then there are the basic 3D "Buildings" layer Google provides for 38 metropolitan areas in the US. But, the buildings are just crude grey "blocks" which give you a feel for the layout of buildings in a city.

With Google Earth V4, you can now...

With Google Earth V4, you can now add textures to 3D models. The guys at the Digitally Distributed Environments blog have written about many ways to show and generate 3D buildings - including a stereoscopic 3D rendering, and using LIDAR side-looking-radar-like technology. Recently, they posted a city block in 3D with quality textures applied for viewing with the new Google Earth V4 (beta). Check out the city block here (only GE V4 - 4 MBytes). Here's what they say about the technology used to make it:

We have placed online a first draft output using our in-house software to obtain accurate height/facade data from photographic modelling. Using a camera calibrated algorithm we can ensure accurate placing of windows/doors etc to rapidly create city models.

Here are some other examples of buildings for viewing with Google Earth V4 with textures (you should delete each previously loaded set of models out of your Places before loading the next one to conserve memory - or just shut down GE V4 and restart it for the next one):
