The problem I'm having is that when the gui first starts the map does not display. I can click the "Zoom All" button on the nav bar, and then the map will appear correctly. I'm attaching the code. Any ideas why the map isn't showing up on startup? Hi Matt I have the same problem. If you modify your constructor like this I think the map should appear... public MoverGUI2() throws URISyntaxException { setSize(600, 600); initComponents(); final MapContext context = buildContext(); navBar.setMap(map); map.getRenderingStrategy().setContext(context); this.addComponentListener(new ComponentAdapter() { @Override public void componentShown(ComponentEvent e) { try { map.getRenderingStrategy().setMapArea(context.getLayerBounds()); } catch (IOException ex) { throw new RuntimeException("bummer"); } } }); } Although this works for me it seems like a really ugly hack and it uses a deprecated method. If anyone knows a more elegant solution please sing out. Thanks Michael.  That worked for me as well. What I don't understand, and likely shows my shallow knowledge of the subject matter, is that the deprecation remark in the StreamingStrategy interface says to use an AffineTransform, instead of Envelope.  I don't understand how one would do that.
