Description
Latitude SHOULD be normalized to within 0-90 degrees with a maximum of 4
digits.
It is possible to specify the direction to either North of the equator or South of the
equator.
Longitude SHOULD be normalized to within 0-180 degrees with a maximum of 4
digits.
It is possible to specify the direction to either East of the prime meridian or West
of the prime meridian.
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.
The Map Datum used for the coordinates given in this Option

WGS84: (Geographical 3D) - World Geodesic System 1984, CRS Code
4327, Prime Meridian Name: Greenwich.

NAD83/NAVD88: North American Datum 1983, CRS Code 4269, Prime
Meridian Name: Greenwich; The associated vertical datum is the North
American Vertical Datum of 1988 (NAVD88). This datum pair is to be used
when referencing locations on land, not near tidal water (which would use
Datum = NAD83/MLLW).

NAD83/MLLW: North American Datum 1983, CRS Code 4269, Prime
Meridian Name: Greenwich; The associated vertical datum is Mean Lower
Low Water (MLLW). This datum pair is to be used when referencing locations
on water/sea/ocean.
