Coordinates Location

Latitude:
Latitude SHOULD be normalized to within 0–90 degrees, with a maximum of 4 digits.
You can specify the direction as either North of the equator or South of the equator.

Longitude:
Longitude SHOULD be normalized to within 0–180 degrees with a maximum of 4 digits.
You can specify the direction as either East of the prime meridian or West of the prime meridian.

Altitude:
Altitude SHOULD be normalized to within -­‐32767 to 32767, with a maximum of 4 digits.
You can 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 that 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.

 State:
