Class MapGeoPoint

java.lang.Object
globus.glmap.MapGeoPoint
All Implemented Interfaces:
Serializable
public class MapGeoPoint extends Object implements Serializable
A geographic point in WGS84 latitude/longitude degrees.

To convert to/from the internal map coordinate system used by the renderer, use MapGeoPoint(MapPoint) / set(MapPoint) and MapPoint(MapGeoPoint).
