The majority of formats require the same two steps for visualization on a GXY view. To visualize KML data:

  1. Decode the data into an ILcdModel using an ILcdModelDecoder.

  2. Create an ILcdGXYLayer for the ILcdModel and add it to the ILcdGXYView. 

//First create the model
ILcdModelDecoder decoder =
    new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class));
ILcdModel model = decoder.decode("Data/Kml/luciad.kml");

//Create a layer for the model
ILcdGXYLayer layer = new TLcdKML22GXYLayerFactory().createGXYLayer(model);
//Wrap the layer with an async layer wrapper to ensure
//that the view remains responsive while data is being painted
layer = ILcdGXYAsynchronousLayerWrapper.create(layer);

//Add the async layer to the GXY view (an ILcdGXYView)
view.addGXYLayer(layer);

This results in a KML layer with styling as defined in the KML file.

This code snippet uses the TLcdCompositeModelDecoder, initialized with all model decoders available in the service registry.

The model decoder class that is actually responsible for decoding KML data is the TLcdKML22ModelDecoder.
