[Geomoose-users] Identify Attributes on a WMS

[Len Kne]

This works...

http://www.datafinder.org/wmsconnector/com.esri.wms.Esrimap/MN_MetroGIS_DataFinder_WMS_Recreation_Tourism?&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&WIDTH=100&HEIGHT=100&X=50&Y=50&EXCEPTIONS=application/vnd.ogc.se_xml&LAYERS=bikeways&QUERY_LAYERS=bikeways&BBOX=-94,44.5,-92,45.6&SRS=EPSG:4326&INFO_FORMAT=text/html&FEATURE_COUNT=100

Strange, because in the GetFeatureInfo it looks like 26915 is supported.

So, I've been working on this for a couple months now - still no luck! I've stopped using a mapfile and I now have my wms only as a source in my mapbook file. I am hitting the wms on the map with the identify tool and I am trying to get the identify.php to send the proper GetFeatureInfo request so that it can populate the wms_record.html. As an example, I am using the wms services at www.datafinder.org<http://www.datafinder.org>. The url that the identify.php is building for my request is this:

http://www.datafinder.org/wmsconnector/com.esri.wms.Esrimap/MN_MetroGIS_DataFinder_WMS_Recreation_Tourism?&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&WIDTH=100&HEIGHT=100&X=50&Y=50&EXCEPTIONS=application/vnd.ogc.se_xml&LAYERS=bikeways&QUERY_LAYERS=bikeways&BBOX=508702.025,4993206.245,508902.025,4993406.245&SRS=EPSG:26915&STYLES=&INFO_FORMAT=application/vnd.ogc.gml
As you can see if you hit this url, I am not getting any attribute information back. Any ideas why? Is there something missing from my request?

(Yes, the wms layer is queryable.)

Thanks for your help!

In your mapfile that you are trying to identify on are you using?
                                METADATA
                                                'wms_record'    'identify_parcel.html'
                                END

I believe that is what tells the GeoMOOSE code to make a WMS identify request versus a MapServer identify request.  Have you look to see what firebug is return for results?  When I look through the identify.php code it appears to all be in there, but it is looking for the wms_record parmater in the mapfile.

Like I said I have not tried to use this feature myself but it is suppose to be supported.  Hope this helps you debug it a little bit more.

Thanks Brian,

Yep, the WMS source should have attributes available for request. Here's my current METADATA code. As you can see, I think I've thrown everything but the kitchen sink in there. If you have any ideas or see any glaring errors let me know.

LAYER...
   METADATA
      "wms_identify" "identify_data.html"
      "wms_record" "identify_data.html"
      "wms_title" "layertitle"
      "wms_srs" "EPSG:26915"
      "wms_name" "layername"
      "wms_server_version" "1.1.1"
      "wms_format" "image/gif"
      "wms_styles" ""
      "wms_exceptions" "application/vnd.ogc.se_inimage"
      "wms_request" "GetMap"
      "wms_request" "GetFeatureInfo"
      "wms_include_items" "all"
      "wms_feature_info_mime_type" "text/html"
    END
    DUMP TRUE
    TEMPLATE '/ms4w/.../identify_data.html'
    TOLERANCE 3
...END

Liesa,
First thing you will have to figure out is if the WMS source has setup any attributes to return with a getinfo wms request.  It should be published in the GetCapbilities if it is.  Not all WMS servers are setup by default to return all attributes.

I have never tried to use the identify with a WMS data source, but I believe Dan added support for it.  I have seen there are configuration settings for the html templates in settings.ini file.

I'm looking for help in setting up an identify on a wms layer. I am using a mapfile to bring in the layer rather than setting up the connection in the mapbook. Does anyone have an example of how to do this? I would like to be able to click with the identify tool on the layer and return attributes in an html template.

Thanks!
