Yes, that URL from the Tomcat log is probably the one that Mapserver
used to request the photo layer.
Recall the error message I mentioned before said "Invalid Lon-Lat
coordinates, must specify at least one (lon,lat) pair correctly;
Longitude must be between -170 and -60 Latitude must be between 15 and
75 ". The bbox in your URL is outside that range.

Thanks for the reply. I tried changing the bounding box and still
nothing. I even removed all the layers except the wms layer to make
sure it wasn't any conflict with the other layers.
I noticed this message in red after I stopped the Tomcat server. It
has only appeared a few times after stopping the server.

Do you think that it is possible that the url for this layer is
somehow being requested exactly how it appears in this Tomcat message?

Subject: Re: [UMN_MAPSERVER-USERS] WMS Layer Problem

I made a WMS request in my browser using the request parameters
specified in your photo layer:
http://terraservice.net/OgcMap.ashx?request=getmap&service=wms&version=1.1.1&width=500&height=500&layers=DOQ&bbox=-170,60,-150,75&srs=EPSG:4326&format=png
The WMS gave an error: "Invalid Lon-Lat coordinates, must specify at
least one (lon,lat) pair correctly; Longitude must be between -170
and -60 Latitude must be between 15 and 75 "
With a different lat-long bounding box it seems to work. I tested
with bbox=-124,46,-110,52. I think the source WMS server doesn't like
your bounding box.
That's just a guess. I don't know exactly what WMS URLs mapserver is
using to request the photo layers. If you have a way to intercept
those outgoing URLs that should give you enough clues to fix the
problem.

Hi, I'm new to the Mapserver Listserv. I am having problems
displaying the wms layer on my map. My problem is that I don't see
any aerial shots at all. It is as if the map is being drawn without
the layer.
Here is a snippet out of my map file where the wms layer is defined:
LAYER
NAME "photo"
STATUS DEFAULT
TYPE RASTER
MINSCALE 10000
#MAXSCALE 10000
CONNECTIONTYPE WMS
CONNECTION "http://terraservice.net/OgcMap.ashx?";
METADATA
"wms_srs" "EPSG:4326"
"wms_title" "Orthophoto"
"wms_name" "DOQ"
"wms_server_version" "1.1.1"
"wms_format" "image/png"
"wms_layers" "doq"
"wms_group_title" "background"
"wms_onlineresource" "http://terraservice.net/OgcMap.ashx?";
"wms_latlonboundingbox" "-170 -60 15 75"
#"wms_connectiontimeout" "120"
END
PROJECTION
"init=epsg:4326"
END
DEBUG ON
END
BTW, my map extent is -178.21759836236586 18.924781799316406
-66.96927103600244 71.40623535327121. Thanks for your reply.
