<div>Matt,</div><div><br></div>For using the World Wind WMS layers you referenced this is what you would add to your map assuming that you are using the default projection for OpenLayers (EPSG:4326)<div><br></div><div><div>

Styles is not necessary unless you are looking for a specific theme. If so look in the above example string again and you will see styles=visual, visual is what you would specify in the styles definition for OpenLayers. Be sure you use the tileSize definition that matches the width and height from the TilePattern string.</span></span></font></div>

I have 2 questions:
<br>1. Is it possible to show World Wind WMS Layers from OpenLayers as in <a href="http://onearth.jpl.nasa.gov/tiled.html" target="_blank">http://onearth.jpl.nasa.gov/tiled.html</a>?
<br>I can hit their wms from my browser:
<br><a href="http://wms.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&srs=EPSG:4326&format=image/jpeg&styles=visual&width=512&height=512&bbox=-180,-166,76,90" target="_blank">http://wms.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&srs=EPSG:4326&format=image/jpeg&styles=visual&width=512&height=512&bbox=-180,-166,76,90</a>
<br>but can't seem to connect to it using any of the openlayers.layer.classes.
<br>
<br>2. I also downloaded the NLT Landsat 7 Visible Color-Level 0 cache pack from <a href="http://www.worldwinddata.com/" target="_blank">http://www.worldwinddata.com/</a>
<br>How do I use OpenLayers.Layer.WorldWind to show that layer? I looked at <a href="http://openlayers.org/dev/examples/worldwind.html" target="_blank">http://openlayers.org/dev/examples/worldwind.html</a> but was even more confused after looking at that page's source.
<br>The cache pack uzipped to my harddrive as a folder entitled '0'; subfolders entitled '0015' through '0075'; and then images such as '0015_0046.jpg'
<br>Thanks,
<br>Matt<br>_______________________________________________<br>
