Bringing new dimension (literally) to location data is the field of "3D location." This essentially takes typical lat/long coordinates and adds a Z-axis. It brings new meaning in the form of elevation, which comes in handy in places like high-rise buildings and shopping malls. This is where Polaris Wireless hangs its hat. The company uses several inputs like barometric pressure to pinpoint mobile device locations using all three dimensions. This can have many use cases such as helping emergency responders show up to the correct floor of a building.
