I have had some problems connecting to ESRI WMS servers.
I am not a WMS expert, but I have briefly looked at the
WMS 1.0.0 specification.
My Mapserver setup is:
>MapServer version 3.5 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
>SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
>INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=SDE INPUT=GDAL INPUT=SHAPEFILE
I have successfully connected my WMS Client to Mapserver-based
WMS Servers. I have not succeeded in connecting to ESRI-based
WMS Servers.
I have tested against
"www.geographynetwork.com/servlet/com.esri.wms.Esrimap?ServiceName=ESRI_World"
and have used cubewerx to check the expected output.
I have tried the following CONNECTION string:
"http://www.geographynetwork.com/servlet/com.esri.wms.Esrimap?ServiceName=ESRI_World&WMTVER=1.0.0&LAYERS=rivers&STYLE=default&SRS=4326&Format=image/gif&TRANSPARENT=false"
This is my LAYER definition
------------------------------------------------------------------------
LAYER
NAME "esri"
METADATA
"wms_title" "ESRI - World"
"wms_srs" "epsg:4326"
"wms_connectiontimeout" "1000"
END
TYPE RASTER
STATUS DEFAULT
CONNECTION "http://www.geographynetwork.com/servlet/com.esri.wms.Esrimap?ServiceName=ESRI_World&WMTVER=1.0.0&LAYERS=rivers&STYLE=default&SRS=4326&Format=PNG&TRANSPARENT=false"
CONNECTIONTYPE WMS
PROJECTION
"init=epsg:4326"
END
END #layer esri
------------------------------------------------------------------------
The message is:
msDrawRaster(): Image handling error. Unrecognized or unsupported image format
If I use only Mapserver WMS Servers, everything works fine...
If I include a "request=map" in the CONNECTION, I get a blank image at
scales where the rivers show up at cubewerx's client.
I must be missing something...
These are the capabilities of:
