programatically adding USGS Digital Ortho

[mjohnson]

Hello,

I am trying to access the USGS Digital Ortho in my Java application using WW Java SDK version worldwind-0.6.317.12858 on a Windows XP machine. I have a WolrdWindGLCanvas and ask for the layers as follows:

WorldWindowGLCanvas wwCanvas = new WorldWindowGLCanvas();
LayerList layers = wwCanvas.getModel().getLayers();

I see only the following layers:

layer = Stars
layer = Atmosphere
layer = NASA Blue Marble Image
layer = Blue Marble (WMS) 2004
layer = i-cubed Landsat
layer = USDA NAIP
layer = MS Virtual Earth Aerial
layer = USGS Urban Area Ortho
layer = Place Names
layer = World Map
layer = Scale bar
layer = Compass

I see the worldwind.layers.xml does not have USGS Digital Ortho. Is this the problem? What do I add to get it?

If not, How can I add USGS Digital Ortho?

Thanks

Yes, as you suspect the best way to to display the USGS Digital Ortho layer in your application's default layer list is to add it to worldwind.layers.xml. Add the following Layer element after the element for USGS Urban Area Ortho:

<Layer href="config/Earth/USGSDigitalOrthoLayer.xml" title="USGS Digital Ortho" actuate="onRequest"/>

Thanks,
Dave

Thanks! That worked
