public class JXMapViewer
extends javax.swing.JPanel
implements java.beans.DesignMode

A tile oriented map component that can easily be used with tile sources on the web like Google and Yahoo maps, satellite data such as NASA imagery, and also with file based sources like pre-processed NASA images. A known map provider can be used with the SLMapServerInfo, which will connect to a 2km resolution version of NASA's Blue Marble Next Generation imagery. @see SLMapServerInfo for more information. Note, the JXMapViewer has three center point properties. The addressLocation property represents an abstract center of the map. This would usually be something like the first item in a search result. It is a GeoPosition. The centerPosition property represents the current center point of the map. If the user pans the map then the centerPosition point will change but the addressLocation will not. Calling recenterToAddressLocation() will move the map back to that center address. The center property represents the same point as the centerPosition property, but as a Point2D in pixel space instead of a GeoPosition in lat/long space. Note that the center property is a Point2D in the entire world bitmap, not in the portion of the map currently visible. You can use the getViewportBounds() method to find the portion of the map currently visible and adjust your calculations accordingly. Changing the center property will change the centerPosition property and vice versa. All three properties are bound.
