[mapserver-users] RE OGR csv - no field names

[Ian Walberg]

Jeff,

Many thanks that worked great.

Next is there any way of getting the row ID as part of the data passed to mapserver?

We are planning to serve this data as a WFS layer.

Thanks

Ian

Simon is right, very nice, specifying the field name to classify in the vrt works, for a csv without field names:

<OGRVRTDataSource>
     <OGRVRTLayer name="occurrence">
         <SrcDataSource relativeToVRT="1">CSV:occurrence.txt</SrcDataSource>
         <GeometryType>wkbPoint</GeometryType>
         <LayerSRS>WGS84</LayerSRS>
         <GeometryField encoding="PointFromColumns" x="field_37" 
y="field_38"/>
         <Field name="name" src="field_51" type="String" width="100"/>
     </OGRVRTLayer>
</OGRVRTDataSource>



LAYER
   NAME "occurrence"
   TYPE POINT
   STATUS ON
   CONNECTIONTYPE OGR
   CONNECTION "../occurrence.vrt"
   CLASSITEM "name"
   CLASS
     NAME "Occurrences"
     EXPRESSION "ttt"
     STYLE
       SYMBOL 7
       SIZE 10
       COLOR 0 0 0
     END
   END
END # Layer
