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

[Simon Mercier]

why not use a vrt file instead!  http://www.gdal.org/drv_vrt.html

<OGRVRTDataSource>
     <OGRVRTLayer name="precipitation">
         <SrcDataSource>precipitation.csv</SrcDataSource>
         <GeometryType>wkbPoint</GeometryType>
         <LayerSRS>EPSG:4326</LayerSRS>
         <GeometryField encoding="PointFromColumns" x="lon" y="lat"/>
         <Field name="precipitation_mm" src="prec_mm"/>
     </OGRVRTLayer>
</OGRVRTDataSource>
