[Mapserver-users] VirtualSpatialData (OGR Connectiontype)

[Julien, Heryk]

Hi,
I'm trying out the Virtual Spatial Data procedure in MapServerWiki
(http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?VirtualSpatialData) with IIS
and an Access 2000 ODBC connection.

I keep on getting the following error message when I attempt ton see my map:

msDrawMap(): Image handling error. Failed to draw layer named 'MGWI_TBLLOC'.

msOGRFileOpen(): OGR error. Open failed for OGR connection `mgwi.ovf'. File
not found or unsupported format.

Anyone can help me?



Here is my virtual file (mgw.ovf):

<OGRVRTDataSource>
    <OGRVRTLayer name="MGWI_TBLLOC">
        <SrcDataSource>ODBC:MGWI_MAPSERVER</SrcDataSource> 
 	<SrcLayer>tblloc</SrcLayer> 
	<GeometryType>wkbPoint</GeometryType>
	<!-- LayerSRS>WGS84</LayerSRS !-->         
	<GeometryField encoding="PointFromColumns" x="x" y="y"/> 
    </OGRVRTLayer>
</OGRVRTDataSource>




My virtual layer is in the same directory as my shapefiles:

SHAPEPATH "d:\webcgcq\lcnp\mapserver_demo\maritimes\data\shp\geo83"




Here is the section of my mapfile where I call my virtual layer:

LAYER
	NAME "MGWI_TBLLOC"
	TYPE POINT
	CONNECTIONTYPE OGR
	CONNECTION "mgwi.ovf"
	DATA "MGWI_TBLLOC"
	STATUS DEFAULT
	LABELITEM "LOCID"
	PROJECTION
		"init=epsg:26920"
	END #projection
	CLASS
		SYMBOL 'circle'
		SIZE 8
		LABEL
			COLOR 132 31 31
			SHADOWCOLOR 218 218 218
			SHADOWSIZE 2 2
			TYPE TRUETYPE
			FONT arial-bold
			FORCE true
			SIZE 10
			POSITION auto
			PARTIALS FALSE
			MINDISTANCE 0
			BUFFER 2
		END # end of label
	    TEMPLATE
"d:\webcgcq\lcnp\mapserver_demo\maritimes\templates\field_capt_query.html"
	END # CLASS
END # LAYER
