[OpenLayers-Users] NationalAtlas.gov WMS usage

[Pierre GIRAUD]

I played with this a bit, and the following worked for me :

map = new OpenLayers.Map('map', {
                projection: new OpenLayers.Projection("EPSG:2163"),
                units: "m",
                maxResolution: 'auto',
                maxExtent: new OpenLayers.Bounds(-5720171, -2783739.25,
                                                 4279073, 4487617),
                controls: [
                       new OpenLayers.Control.PanZoomBar(),
                       new OpenLayers.Control.ScaleLine(),
                       new OpenLayers.Control.MousePosition(),
                       new OpenLayers.Control.Navigation()
               ],
               numZoomLevels: 20
            });

            map.addLayer(new OpenLayers.Layer.WMS("National Atlas States",
               "http://nationalatlas.gov/natlas/WMSProcess.asp",
               {layers: 'grid,states', format:'gif', exceptions:
'Blank', version: '1.0.0'}
            ));


            map.zoomToMaxExtent();

Hope this helps,
Pierre
