Class EarthLocationLite

java.lang.Object

visad.ThingImpl

visad.DataImpl

visad.Tuple

visad.RealTuple

visad.georef.EarthLocationLite

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Data, EarthLocation, LatLonPoint, RealTupleIface, Thing, TupleIface

public class EarthLocationLite
extends RealTuple
implements EarthLocation

This provides a LoCal EarthLocation that is much faster to create than the EarthLocationTuple. Assumes units of lat/lon are degrees and Altitude is meters.
