Class IlvGeodesicCoordinateFormatter

java.lang.Object

ilog.views.maps.IlvAbstractCoordinateFormatter

ilog.views.maps.IlvGeodesicCoordinateFormatter

All Implemented Interfaces:

IlvPersistentObject, IlvCoordinateFormatter

public class IlvGeodesicCoordinateFormatter
extends IlvAbstractCoordinateFormatter

The IlvGeodesicCoordinateFormatter class is a utility class that converts longitude and latitude (measured in radians) into decimal Degree format such as N64&B0;75 E167&B0;67. Ellipsoid is not used in this implementation of IlvCoordinateFormatter

Since:

JViews 7.5
