Google is collaborating with Ford and Siemens on a product they are calling IntoSite. As you will see in the video it leverages Google Earth and therefore GIS technology, plus it adds BIM to take you onto the shop floor, in this case.
This is something that I have discussed in a couple of presentations on data modeling. Namely the idea of an integrated Built Environment data model that extended from the globe to your desk. In fact, it really is the integration of CAD and GIS, something I have been working on my entire career. Looks like this team has made it a reality.
More support for the map to be the operating system as discussed recently.
