[OpenLayers-Users] Opacity Kills Map

Fri Jan 18 03:31:06 EST 2008

There are syntax errors in your code. (');' -> ',')
Here is the code for the layers precip and nexrad that worked for me :

var precip = new OpenLayers.Layer.WMS( "Total Storm Precip",
    "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/ntp.cgi?",
    {layers: "nexrad_stormtotal_precip", transparent: "true", format:
"image/png" },
    {isBaseLayer: false, opacity: 0.5});

 var nexrad = new OpenLayers.Layer.WMS( "Nexrad Radar 5min",
    "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi?",
    {layers: "nexrad_base_reflect", transparent: "true", format:"image/png" },
    {isBaseLayer: false, opacity: 0.5});
