The Next Frontier: Indoor Maps

Mapping streets and buildings is the hard part. But the even harder part is mapping indoors. Not only is Google acquiring floor plans for major buildings and venues, but we’re also working out ways to provide positioning data inside those buildings. When GPS doesn’t work, how do you find your place on the map?

How long before Google has a network of devices indoors to provide a terrestrial version of GPS?

Google isn't really doing indoor maps the right way. They still see maps conceptually as flat where the user has to translate into 3d space.  It's AR all the way down...

I'm going to have to go with the previous question, do you take the red pill or the blue one?
