The critical algorithm at the core of it all is called "SIFT". ... Then you have sets of 2D coordinates of 3D points under several projections (images). This data defines a set of equations which you can solve to get the relative camera positions and 3D coordinates of the feature points.

With Bing, they're probably doing it this way. Google on the other hand took a short cut and gathered the geometry directly using time of flight laser scanners. Although with the recent data from the ski slopes it looks like they ditched the laser scanners and are reconstructing the geometry from the images like you suggest.

Here here! EditPlus is quite excellent. Only piece of shareware I've ever bought. Only downside I've found it that it doesn't handle massive files (>500MB) as well as TextPad.
