I’m going to make a prediction based on this fun little picture I found on the Sketchup site: http://www.sketchup.com/?id=20&gid=318#top In case you can’t tell what it is, it’s a sketchup model sitting on top of a satellite imagery map. My prediction is that google will use sketchup heavily with their google earth and google maps system with the goal being to recreate entire cities in 3D view. They’ve already done it with a lot of the major buildings in the US. Maybe they’ll give sketchup out for free to businesses who want to be represented in detail on google earth? You could import a 3d studio or autocad drawing into sketchup, save off the resulting 3d model, and google could implement it. It would be a cheap and easy way to get “3D” satellite imagery.
