Google Earth Building Textures into Unity

I'm trying to get building textures from Google Earth and apply them to my own models. My overall goal is to be able to walk around a city virtual reality.

So far, I've found some information from the samples provided by google. In one example, the textures are held in texture folder.

If you have any ideas as to how I could go about this I would greatly appreciate the help.
