Hi,

It appears that the requests don't go directly to a WMS server, but  
through some sort of web services gateway:

http://gisdata.usgs.gov/xmlwebservices/(S(oaev4rj0yenlxz55f2c40uek))/ 
getqueryservice.aspx? 
Background_Color=255,255,255&Transparent=true&Layer_ID=&BBOX_String=-248 
. 
95,17.5,7.20000000000002,72&Service_Name=undefined&Output_format=IMAGE&O 
utput_image=gif&Server_Address=localhost&Image_Width=940&Image_Height=20 
0&QueryService_Query=OBJECTID%20in%20() 
&Renderer_Type=POLYGON&fill_color=200,10,10&fill_type=bdiagonal&Outline_ 
Color=200,10,10

Maybe this, in turn, makes a call to a WMS? Anyhow One of the params,  
Layer_ID is empty. Setting Layer_ID to 1 returns a 1x1 blank pixel.

Make of that what you will,

Cheers,

Andrew
