Interactive 3d simulations of cities continue to proliferate:
Google Blog: Warsaw, Prague and Oslo have joined the growing list of phototextured cities in the 3D Buildings layer of Google Earth. Like other major cities these 3D models are predominantly autogenerated, yet they also contain a number of Google SketchUp models generated by the user community. While the autogenerated models are good quality, user-generated models are often better because ground-based photos can produce a higher quality model than ones generated using aerial imagery.
