The layers are likely in the zoomify format so you may want to research how to use zoomify layers in OpenLayers.<br clear="all">--<br>Nathan Gerber<br>

Thank You Nathan...I now have access the the NASA WMS in openlayers!
<br>
<br>Any idea on how I would use the downloaded data pack in openlayers? Is that possible?

<br>>
<br>> In the link you posted go to the "GetTileService" When you view the XML take note of the comments in the TilePattern tags. For example:
<br>>
<br>>
<br>>
<br>> request=GetMap&layers=daily_afternoon&srs=EPSG:4326&format=image/jpeg&styles=visual&width=512&height=512&bbox=-180,-166,76,90
<br>>
<br>>
<br>>
<br>> In the above example you would take layers=daily_afternoon and use the daily_afternoon as your layers in the OpenLayers definition. 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.
<br>>
<br>>
<br>> The WorldWind example you reference is accessing the remote WorldWind server for the tiles. It is not intended for accessing a copy of the data that you downloaded.

<br>> I have 2 questions:
<br>>
<br>>
<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>>
<br>>
<br>> I can hit their wms from my browser:
<br>>
<br>>
<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>>
<br>>
<br>> but can't seem to connect to it using any of the openlayers.layer.classes.
<br>>
<br>>
<br>>
<br>>
<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>>
<br>>
<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>>
<br>>
<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>>
<br>>
<br>> Thanks,
<br>>
