GeoPosition

represents a geodetic position with latitude

and longitude

represents a geodetic position with height h relative to the reference ellipsoid.

represents a geodetic position referring to the specified datum.

GeoPosition converts from any type of geographic position. The following coordinate types can be given: GeoPosition, GeoPositionXYZ, GeoPositionENU, GeoGridPosition.

	"ITRF00"	international Terrestrial Reference Frame 2000
	"NAD27"	North American Datum of 1927
	"NAD83CORS96"	North American Datum of 1983 (CORS96)

The complete list of named datums and reference ellipsoids is given by GeodesyData.

GeoPosition coordinates are assumed to have a time coordinate equal to the reference epoch date of the datum.
