com.luciad.geodesy.ILcdGeodeticDatum
as this allows to use geoids for geodetic datums and ILcdGeoReference
instances such as
com.luciad.reference.ILcdGridReference
.public interface ILcdVerticalDatum extends Serializable
ILcdVerticalDatum
is used as a reference system for
lon-lat-height coordinates. It is defined by a geoid. A geoid is defined by
the geoidHeight with respect to an ILcdEllipsoid
.
A height expressed with respect to the geoid is called the orthometric height.
The ellipsoidal height, also called the geodetic height, is the sum of the geoid height and the orthometric height. For a geoid datum where the geoid height equals zero everywhere, the orthometric height equals the ellipsoidal height.
A ILcdVerticalDatum
is always used together with a
ILcdGeodeticDatum
, which is also called a horizontal datum
in this context.
