[mapserver-users] Question about config Mapserver to provide SOS service from postgis table/view

[Miguel-Angel Manso-Callejo (UPM)]

Thank you Stephen

At this moment i can send a GetObservation Request and get response in 
O&M format but i can't understand why sos mapserv don't recognize any 
procedure name or eventTime format.

First: In order to do it i must change DATA sql to:

     DATA "pos from (select pos,fecha,vap from vaporcolumna where 
id='MADR13407S012') as subquery using unique fecha using srid=4326"

Then, when i request data GetObservation the answer is like:

<om:member>
<om:Observation>
<om:samplingTime>
<gml:TimeInstant>
<gml:timePosition>2014-01-29 04:00:00</gml:timePosition>
</gml:TimeInstant>
</om:samplingTime>
<om:procedurexlink:href="*urn:ogc:def:procedure*:2197.7"/>
<om:observedProperty>
<swe:CompositePhenomenongml:id="vap"dimension="2">
<gml:name>Vapor agua columna</gml:name>
<swe:componentxlink:href="urn:ogc:def:property:OGC-SWE:1:fecha"/>
<swe:componentxlink:href="urn:ogc:def:property:OGC-SWE:1:vap"/>
</swe:CompositePhenomenon>
</om:observedProperty>
<om:featureOfInterestxlink:href="http://138.100.61.23:90/cgi-bin/sos-mapserv?service=WFS&version=1.1.0&request=DescribeFeatureType&typename=test_sos_layer"/>
<om:result>
<gml:featureMember>
<ms:test_sos_layer>
<gml:boundedBy>
<gml:EnvelopesrsName="urn:ogc:crs:epsg:4326"srsDimension="2">
<gml:lowerCorner>-4.249658 40.429163</gml:lowerCorner>
<gml:upperCorner>-4.249658 40.429163</gml:upperCorner>
</gml:Envelope>
</gml:boundedBy>
<ms:msGeometry>
<gml:PointsrsName="urn:ogc:crs:epsg:4326"srsDimension="2">
<gml:pos>-4.249658 40.429163</gml:pos>
</gml:Point>
</ms:msGeometry>
</ms:test_sos_layer>
</gml:featureMember>
</om:result>
</om:Observation>
</om:member>
<om:member>

However procedure name don't appear in xml 
<om:procedurexlink:href="urn:ogc:def:procedure:2197.7"/>

Then when i tryed to getObservation using parameter 
/&procedure=urn:ogc:def:procedure:/ mapserver SOS don't recognize any


Second question are related to eventTime request parameter.

I'm trying to use 
&eventtime=2014-01-01T00:00:00+01/2014-01-31T00:00:00+01    and an 
exception apear msSOSGetObservation(): SOS server error. Invalid time 
value given for the eventTime parameter

I must do request with  XML FE format 
&eventtime=%3Cogc:TM_Equals%3E%3Cgml:TimePeriod%3E%3Cgml:beginPosition%3E2014-01-01%3C/gml:beginPosition%3E%3Cgml:endPosition%3E2014-01-31%3C/gml:endPosition%3E%3C/gml:TimePeriod%3E%3C/ogc:TM_Equals%3E

What are the correct ISO time format to operate without XML?

/>/         END
/>/       END
/>/     END
/>/
/>/
/>/  View have this fields:
/>/    Id (pk), pos (geometry), vap (double), fecha (date)
/>/
/>/  Can any one help me informing what i'm doing bad or how must i config in
/>/  order to do it?

You probably need to make sure pos is listed in the geometry_columns
table and associated with your view.

Turn on layer debugging and set DEBUG 5
try to use shp2img so see the log messages and any error messages.
