Longitude
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
Altitude should be normalized to within -2097151.9 to 2097151.9 with a
maximum of 1 digit.
It is possible to select between two altitude types (meters or floors):
 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.
Map Datum
The Map Datum is used for the coordinates given in these options:
 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.
Civic Address Location
IETF Geopriv Civic Address based Location Configuration Information (Civic Address LCI). The total
number of characters for the combined civic address information must not exceed 250 characters.
A couple of notes to the limitation of 250 characters:
1. A non-empty civic address location will use 2 extra characters in addition to the civic address
location text.
2. The 2-letter country code is not part of the 250 characters limitation.
