Rogue Wave® JViews Diagrammer allows you to load an IVL file and this can be a map. If the IVL file contains projection data, Rogue Wave JViews Diagrammer can then place the nodes according to their latitude and longitude properties.

The package ilog.views.sdm.renderer.maps gives access to Rogue Wave JViews Maps for developing your own maps, if you have purchased this product.

The rendering of maps in a diagram is done by the Map renderer, IlvMapRenderer.

Optionally, the zooming policy of the nodes displayed on a map can be controlled by the HalfZooming renderer, IlvHalfZoomingRenderer. which allows you to specify limits in zooming in or out.

If you use a map, your data model should contain latitude and longitude attributes. These attributes can have any names because you can map them to the names latitude and longitude. For details of the formats for latitude and longitude, see The Map renderer.

Refer to the JViews Maps documentation for more information on the integration of JViews Diagrammer with JViews Maps.
