[OpenLayers-Users] National Elevation Data -EROS

you have to declare a width and heght for your map div.

ugly way:
    <div id="map" class="smallmap" style="border:1px solid
blue;width:512px;height:256px;"></div>

and try this init() function:

        function init(){
            map = new OpenLayers.Map( 'map' );
            layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",

"http://imsref.cr.usgs.gov:80/wmsconnector/com.esri.wms.Esrimap/USGS_EDC_Ele
v_NED?",
                    {layers: 'NED.HI_NED',
exceptions:'application/vnd.ogc.se_inimage', format:'image/png'} );
            map.addLayer(layer);
            //map.zoomToMaxExtent();
            map.setCenter(new
OpenLayers.LonLat(lon=-155.44555646516,lat=19.500732399862), 7); //Hawai
        }

Betreff: [OpenLayers-Users] National Elevation Data -EROS

I'm trying to display a layer from the EROS national elevation dataset
hosted by the USGS in openlayers. 

this code isn't working...

                    {layers: 'NED.HI_NED'} ); 
            map.addLayer(layer);

        }

  <body onload="init()"> 
    <h1 id="title">Basic Single WMS Example</h1> 

    <div id="tags"> 
        basic, simple, minimal, cleanup 
    </div> 

    <div id="shortdesc">Show a Simple Map</div> 

    <div id="map" class="smallmap"></div> 

    <div id="docs"> 
        <p>This example shows a very simple layout with minimal controls. 
        This example uses a single WMS base layer.</p> 
    </div> 
  </body> 
</html> 

Can someone please tell me what I'm doing wrong?  I don't appear to be
getting a response in firebug.
