Re: DTED, RPF woes

Hi Jeremy,

The DTEDCoverage layer is for displaying where data is - it just draws
rectangles over the areas where the dted data resides. The DTEDLayer
actually renders the terrain images. Still, you should be able to see
the rectangles for each DTED frame.

I tried your code out, and there was a problem, which I've corrected in
the code below:

getGUI() is a standard layer method that provides a component to use to
adjust the layer parameters. It's used by an application to provide a
control palette.

I had to use new DTEDCoverageLayer() ...

You need to add:

        this.getContentPane().add(mapBean);

otherwise, the mapbean never gets added to the frame.

Also, to see the CIB data, you'll have to zoom in to at least ~ 1:240k.
1:66.66k is the actual scale for the images.
