Hi Chris,

There is a couple of things going on here. First, I don't know how you got the 
image/tiff format in your GetMap url since the capabilities lists other formats 
and the IDV looks for png, jpg, etc. Maybe its the version of the IDV. I am 
getting image/png.

That said, another issue is the extra space in the xlink:href
          <Get><OnlineResource xmlns:xlink="http://www.w3.org/1999/xlink"; 
xlink:href=" http://g0hep12u.ecs.nasa.gov/mapserv-bin/wms_ogc?"/></Get>

We end up encoding that as "%20http://"; which breaks things on our end.

I have fixed the encoding problem and this will be available in tonight's 
nightly build tomorrow (Friday) morning:
