var layer = new OpenLayers.Layer.WMS(name, params, options)
 
the param SRS is set by OpenLayers using the map projection. But you could
overwrite the projection, 
if you set in the options projection:"EPSG:102113".
 
// WMS LAYER: National Elevation Dataset - EROS 
var layer = new OpenLayers.Layer.WMS( "National Elevation Dataset - EROS", 
"http://imsref.cr.usgs.gov:80/wmsconnector/com.esri.wms.Esrimap/USGS_EDC_Ele
v_NED?", 
{layers: "NED.CONUS_NED,NED.PR_NED", 
TRANSPARENT:true, format: "image/png"}, 
{isBaseLayer: false, visibility: true, group:"other", opacity: 0.75,
meta:true, projection:"EPSG:102113"}); 
map.addLayer(layer); 
 
Also the projection is declared with the prefix EPSG.
srs:EPSG:102113 instead srs:102113.

Arnd - 

Something weird is happening with the request because this is my code to
setup layer in openlayers.  This is from firebug so I'm sure its not a cache
issue. 

// WMS LAYER: National Elevation Dataset - EROS 
var layer = new OpenLayers.Layer.WMS( "National Elevation Dataset - EROS", 
"
<http://imsref.cr.usgs.gov/wmsconnector/com.esri.wms.Esrimap/USGS_EDC_Elev_N
ED?>
http://imsref.cr.usgs.gov:80/wmsconnector/com.esri.wms.Esrimap/USGS_EDC_Elev
_NED?", 
{layers: "NED.CONUS_NED,NED.PR_NED", 
srs: "102113", TRANSPARENT:true, format: "image/png"}, 
{isBaseLayer: false, visibility: false, group:"other", opacity: 0.75,
meta:true}); 
map.addLayer(layer); 


And this is the request from firebug

I think its a open layers issue but the bbox parameters look like 102113.

EPSG:3857 is not supported by the wms, see

http://ims.cr.usgs.gov/WMS_Capabilities/USGS_EDC_Elev_NED/capabilities_1_1_1

but you can use EPSG:102113 instead.

Hi - 

I trying to include the EROS data set as part of the National Map at USGS in
an open Layers project.  We are using a spherical Mercator projection
"102113" which would be hard to change at this point.  My requests work when
they are in latitude and longitude but my requests fail when they are in
spherical mecator.  Is there any way to force open layers to make my request
with reprojected parameters as latitude longitude rather than spherical
Mercator? 


This isn't working
