Building Maps

Me in December 2011:

I can’t wait for the day when my iPhone can navigate as well to a location within a building as it can to an address, or for when I can drop a pin when I park my car in an underground garage and be able to navigate directly back to it.

And now this from the Wall Street Journal:

Apple has acquired indoor-GPS company WifiSLAM […] The two-year-old startup has developed ways for mobile apps to detect a phone user’s location in a building using Wi-Fi signals. It has been offering the technology to application developers for indoor mapping and new types of retail and social networking apps.

Can’t come soon enough.
