Roses is the first city in Spain to get their entire city in 3D for Google Earth. The models are currently the basic gray buildings without textures. But, they are part of the Google Earth 3D Buildings layer. Just search for "Roses, Spain" to see for yourself. Google has a program called Cities in 3D (read more) to help city planners provide Google with data so their cities can be included in the layer. The program was just expanded to several European countries (including Spain) in early June. According to GEB reader Albert Garcia, they are also working to add SketchUp models with photo-textures for Roses.
Google has dozens of cities now where a large percentage of the urban area is modeled in 3D (more in the US than any other country at the moment). Here is a list of some cities in Europe where most of the city is in 3D: Zurich, Munich, Amsterdam, Hamburg, and Westport in Ireland. Berlin also has a huge 3D collection they created themselves, but it's not part of the built-in GE layer. Similarly, Dresden in Germany also did their own layer which is not yet part of the built-in layer. And, let's not forget, probably the most 3D data available for any country is in Japan. Nearly every structure for several major cities is rendered if you turn on the 3D Buildings layer and visit cities in Japan.
