[Gdal-dev] Problem with Mapserver Virtual Spatial Data (ogr)

[Christian Wilmes]

Hello,

first of all sorry for cross posting, but I've got no idea where I have to
search the mistake so I post it to the GDAL and the Mapserver Mailinglist.

I'm trying to publish a WFS-Server. The Data (only Point-Data) are in a
PostgreSQL-Database (no PostGIS!). So the connection to the data is over
"Virtual Spatial Data". The getCapabilities and DescribeFeatureType request
both work very well. Only the GML-Document getting with the getFeature
request is not correct. The number of features in the GML-Document are
correct too every time, but the features are not in the Bounding Box. The
features in the GML-Document are always the feature which are on the top of
the table they come from. Only the number of feature is correct. The MBR
(Minimum Boundig Rectangle) on the top of the GML-Document amasingly the
correct one. So it don't fit to the features in the document. Testing the
connection with "ogrinfo" and a Boundig-Box is working correct. If I'm
trying to make a WMS-Server with the same Data and the same OGR-file it
works very well.

So here is my Mapfile:

MAP
	NAME WFS_Server
	STATUS ON
	WEB
		METADATA
			"wfs_title"            "WFS Server" 
			"wfs_onlineresource"   "http://127.0.0.1/cgi-bin/mapserv.exe?"
			"wfs_srs"               "EPSG:4326"
		END
	END

	PROJECTION
		"init=EPSG:4326"
	END

	
	LAYER
		NAME myWFS
		METADATA
			"wfs_title"    "myWFS"
			"gml_include_items" "all"  
		END
		TYPE POINT
		STATUS ON
		CONNECTIONTYPE OGR
		CONNECTION "test.ovf"
		PROJECTION
			"init=EPSG:4326"
		END
		DUMP TRUE

	END
END





and the OGR-File test.ovf:

<OGRVRTDataSource>
    <OGRVRTLayer name="feature">
        <SrcDataSource>PG:host=192.168.5.86 user=cwilmes dbname=rosoapcw
password=xxx</SrcDataSource> 
 	<SrcLayer>feature</SrcLayer> 
	<GeometryType>wkbPoint</GeometryType> 
        <LayerSRS>EPSG:4326</LayerSRS>
	<GeometryField encoding="PointFromColumns" x="lat" y="lon"/> 
    </OGRVRTLayer>
</OGRVRTDataSource>


Here is a URL which I used for testing the WFS
getFeature-Request:
http://localhost/cgi-bin/mapserv.exe?&REQUEST=GetFeature&VERSION=1.0.0&SERVICE=WFS&TYPENAME=myWFS&&BBox=9.98,7.98,10,8


....and here is the result:

I will be very thankful for every idea where the mistake could!

Please excuse my bad english!
