Dear List,
posting to this list for the first time and am promptly rejected by the
system. Hopefully it is not an omen. :-) Well, here is my question again.
Dear List,
I am in the process of setting up a Sensor Observation Service (SOS) for the
first time using a Kubuntu-Linux machine and the following Mapserver:
MapServer version 4.10.0-beta3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=SOS_SERVER INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE
My data is sitting in a Postgis table which I can easily access via WMS.
I have consulted the documentation at:
http://mapserver.gis.umn.edu/docs/howto/sos_server/
and when trying out the examples given there the GetCapabilities and
DescribeSensor Requests work fine so far but the GetObservation Request does
not.
My idea of how the GetObservation Request should work is that data in a
specific column in my Postgis table is returned when I define it in my SOS
server mapfile. Here is a snippet of the mapfile:
<SNIP>
LAYER
NAME test_sos_layer
DUMP TRUE
METADATA
"sos_procedure" "SW01UTL001"
## REQUIRED
"sos_offering_id" "r_wert"
## REQUIRED
"sos_observedproperty_id" "r_wert"
## REQUIRED
"sos_describesensor_url" "http://localhost/temp/SW01UTL001.xml"; ## REQUIRED
END
TYPE POINT
STATUS ON
CONNECTIONTYPE postgis
CONNECTION "user=myuser dbname=mydb host=localhost port=5432"
DATA "the_geom FROM (SELECT * FROM mytable) AS foo USING UNIQUE gid USING
SRID=31467"
PROJECTION
'init=epsg:31467'
END
CLASS
NAME 'r_wert'
STYLE
SYMBOL 'circle'
SIZE 5
COLOR 255 100 50
OUTLINECOLOR 0 0 0
END
END
END
</SNIP>
When I send this there is no error but all I get back is this:
<om:ObservationCollection gml:id="r_wert"
xsi:schemaLocation="http://www.opengeospatial.net/om http://schemas.opengis.net/om.xsd"/>
Where am I going wrong? Any help on pointing me in the right direction is
highly appreciated!
Best regards,
Hinrich
