Hi All, I have been having some issues using the UNION option in the mapfile. I'm trying to set up a WMS server with several "source" raster layers and provide them all as a single union layer to the client. I don't want the source layers visible in the GetCapabilities, only the union layer so I have been using a combination of the own_enable_request and CONNECTIONTYPE UNION. It seems to work in the GetCapabilites, only the union layer appears however only blank images are returned from the GetMap requests. The layers portion of my mapfile is below, I have set the "ows_enable_request" "*" in the WEB METADATA. Any help would be much appreciated
