[OpenLayers-Users] What's wrong with this program?

Tue Mar 11 21:23:01 EDT 2008

Hi Darrin,

The WMS url that is being built is:
http://svs.gsfc.nasa.gov/cgi-bin/wms?LAYERS=3338_24550&VERSION=1.3.0&FORMAT=image%2Fpng&WIDTH=256&HEIGHT=256&STYLES=opaque&CRS=CRS%3A84&BBOX=-180,-90,180,270&SERVICE=WMS&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A4326

If you put that in your browser, you'll get an XML describing the error.

PS: See http://trac.openlayers.org/wiki/FrequentlyAskedQuestions#HowcanIseetheURLstringthatOpenLayersissendingtoaWMSserver
