Altitude
Altitude SHOULD be normalized to within -32767 to 32767 with a maximum of 4
digits.
It is possible to select between two altitude types (floors or meters).
Meters: Representing meters of Altitude defined by the vertical datum specified.
Floors: Representing altitude in a form more relevant in buildings which have
different floor-to-floor dimensions. An altitude = 0.0 is meaningful even outside a
building, and represents ground level at the given latitude and longitude. Inside a
building, 0.0 represents the floor level associated with ground level at the main
entrance.
