Immerse the world on Bing, Google and Foursquare

One of the problems facing mappers is the abundance of locations to map.  My idea will aid in this using crowd sourcing.  If one takes a 360 degree video of a location from 2 or more spots, you should be able to build up a 3D visualization of the area. So in a store for example you go to 3 corners or up and down the isles and take a video on your iPhone or android or windows phone. Then you submit the video in to Bing who uses a Photosynth like technique to "build" the 3d map. You tag the map with its gps location. As more people do this we will be able to build up 3D virtualizations of huge amounts of areas. Where foursquare fits in with this is to add the social location aspect to it. You can encourage people to submit these videos by maybe creating new categories in foursquare like Chief Videographer for the person submitting the most videos etc...
