[mapserver-users] MapServer SOS Configuration

[Ebrahim Poorazizi]

Hi,

I tried to set up MapServer SOS but I faced a problem: the SOS doesn't
return anything. You may see the map file I have created below:


    MAP
      NAME "SOS_DEMO"
      STATUS ON
      SIZE 400 300
      EXTENT -180 -90 180 90
      UNITS METERS
      SHAPEPATH "C:\ms4w\apps\tutorial\data"
      IMAGECOLOR 255 255 255

      WEB
        IMAGEPATH "C:\ms4w\apps\tutorial\templates"
        IMAGEURL "C:\ms4w\apps\tutorial\images"
        METADATA
          "sos_onlineresource" "
http://127.0.0.1:8282/cgi-bin/mapserv.exe?map=c:/ms4w/mysos.map?"
          "sos_title"          "My SOS Demo Server"
          "sos_srs"            "EPSG:4326"
          "sos_enable_request" "*"
        END
      END

      PROJECTION
        "init=epsg:4326"
      END

      LAYER
        NAME "sos_point"
        METADATA
          "sos_procedure"  "ifgi-sensor-1"
          "sos_offering_id" "WQ1289"
          "sos_observedproperty_id" "Water Quality"
          "sos_describesensor_url" "http://127.0.0.1:8181/DescribeSensor.xml"

        END

        TYPE POINT
        STATUS ON
        DATA 'sospoint'
        PROJECTION
          "init=epsg:4326"
        END
        CLASS
          NAME 'sospoint'
          STYLE
            COLOR 255 128 128
          END
        END
      END
    END


As you see, I tried to retrieve sensor data from a shapefile. The message
returned by the SOS is:

<om:ObservationCollection xmlns:gml="http://www.opengis.net/gml" xmlns:ows="

Although I put 6 observations into the shapefile but the SOS doesn't return
any. Would you please let me know what I should do to resolve the problem?!
