LuciadLightspeedInterface ILcdVerticalDatum

All Superinterfaces:

Serializable

All Known Implementing Classes:

TLcdNullVerticalDatum

Deprecated.

Use the new vertical datum support in 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

An 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.
