Hi List, I am new to the list and have been trying to setup MapServer's SOS Server to serve some observation data. I have created a map file and managed to have GetCapabilities working. But when trying out the GetObservation, I am confused... not much helpful documentation around and have found this discussion from the old SOS User forum : http://osgeo-org.1803224.n2.nabble.com/SOS-disconnect-td1992064.html. However, still confused on how to map a database column to SOS output !?!?
Metadata for the layer in my map file : METADATA "sos_value_alias" "value_test" ## value is the name of the db clumn "sos_value_componenturl" "http://test.org#value_test"; "sos_procedure" "unknown" "sos_offering_id" "waterstorage" "sos_offering_description" "value_test" "sos_observedproperty_id" "9" "sos_describesensor_url" "http://localhost/TEST123.xml"; "sos_srs" "init=epsg:4283" "sos_offering_timeextent" "1900/2010" The database connection is successful and the GetCapabilities return the following sos information : - <sos:Contents> - <sos:ObservationOfferingList> - <sos:ObservationOffering gml:id="waterstorage"> <gml:description>value_test</gml:description> - <!-- WARNING: Optional metadata "sos_offering_name" missing for gml:name --> <gml:srsName>EPSG:4326</gml:srsName> - <!-- WARNING: Optional metadata "sos_offering_intendedapplication" missing for sos:intendedApplication --> - <sos:time> - <gml:TimePeriod> <gml:beginPosition>1900</gml:beginPosition> <gml:endPosition>2010</gml:endPosition> </gml:TimePeriod> </sos:time> <sos:procedure xlink:href="urn:ogc:def:procedure:unknown" /> - <sos:observedProperty> - <swe:CompositePhenomenon gml:id="9" dimension="7"> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:feature" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:identifier" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:ftype" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:value_test" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:type" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:description" /> <swe:component xlink:href="urn:ogc:def:property:OGC-SWE:1:yearofcompletion" /> </swe:CompositePhenomenon> </sos:observedProperty> <sos:featureOfInterest xlink:href="urn:ogc:def:feature:OGC-SWE:3:transient" /> <sos:responseFormat>text/xml; subtype="om/1.0.0"</sos:responseFormat> <sos:resultModel>om:Observation</sos:resultModel> <sos:resultModel>om:Measurement</sos:resultModel> <sos:responseMode>inline</sos:responseMode> </sos:ObservationOffering> </sos:ObservationOfferingList> </sos:Contents> GetObservation (http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/apps/sos/sos_test.map&Request=GetObservation&service=SOS&OFFERING=waterstorage&observedproperty=9&version=1.0.0&responseFormat=text/xml; subtype="om/1.0.0") return the following : <?xml version="1.0" encoding="ISO-8859-1" ?> - <om:ObservationCollection xmlns:gml="http://www.opengis.net/gml"; xmlns:ows="http://www.opengis.net/ows/1.1"; xmlns:swe="http://www.opengis.net/swe/1.0.1"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:sos="http://www.opengis.net/sos/1.0"; xmlns:ms="http://mapserver.gis.umn.edu/mapserver"; xmlns:om="http://www.opengis.net/om/1.0"; gml:id="waterstorage" xsi:schemaLocation="http://www.opengis.net/om/1.0 http://schemas.opengis.net/om/1.0.0/om.xsd http://mapserver.gis.umn.edu/mapserver http://127.0.0.1/cgi-bin/mapserv.exe?map=c:/ms4w/apps/sos/sos_test.map&service=WFS&version=1.1.0&request=DescribeFeatureType&typename=test_sos_layer";> <gml:description xmlns:gml="http://www.opengis.net/gml";>value_test</gml:description> </om:ObservationCollection> My quesions are : 1) How do I map a db clumn to a sos output ?? Do i have to create "sos_dbColumn_alias" for each column ? 2) What's the purpose of "sos_dbColumn_componenturl" ? Do I need to create this for each dbColumn ? 3) I have map the "sos_offering_description" "value_test", why does the getCapabilities and getObservation return "value_test" as a constant rather then retrieving data from the database ? Appreciave if someone could point out what is the problem of the map file or point me to some useful documentation or tutorial on set up SOS in MapServer.
