Now this is interesting and perhaps not good news for Trimble. According to CAD industry veteran Ralph Grabowski Google has come up with an alternative approach for generating 3D building models. Instead of SketchUp they are now using oblique photography – I wonder where they are getting that from.
In any case, according to Ralph that made SketchUp obsolete. It does not seem like a one to one trade off to me, but I am sure Google has a plan.
