Imagine a 3D Google Earth

Imagine a google earth world where millions of enthusiastic users
build replicas of their homes and the stores/ buildings in their
neighborhood and then they become veiwable by anybody else. Wiki style,
people can work collaboratively to improve and constantly update
buildings. What would normally cost billions of dollars for 3D design
company to make available then become part of a 3D vitual town/yellow
pages. And it would be built for free and rapidly.

Like Second Life,
folks could create futuristic worlds — alternative URL’s to the
standard Google Earth. But unlike SL, they would use today’s cities and
towns as a starting place and create scenarios of the future.

Town
planners would then be able to use these models as a starting point for
thinking about scenarios (GIS tools like CommunityViz or INDEX could be
used to do the impact analysis) and those scenarios which more closely
matched the expressed desired future of the citizens would be used to
help create implementation strategies.
