    - VRT file parameters to import Points, Lines, and Polygons

    VRT files are used to import a CSV file containing point, line or polygon data.  Information regarding the VRT file format and parameters can be found at the following:

    https://gdal.org/drivers/raster/vrt.html

    The attached zip file to this article includes a sample set of CSV files and a related VRT file which makes use of WKT geometry field encoding for point, lines and polygons.

    NOTES: 

    1.  The OGRVRTLayer name must be the same as the CSV file name. 

    2.  The relativeToVRT="1" is optional.

    <OGRVRTDataSource>
    	<OGRVRTLayer name="Linestrings">
    		<SrcDataSource relativeToVRT="1">linestrings.csv</SrcDataSource>
    		<GeometryType>wkbLineString</GeometryType>
    		<LayerSRS>WGS84</LayerSRS>
    		<GeometryField encoding="WKT" field="WKT"/>
    	</OGRVRTLayer>
    	<OGRVRTLayer name="Polygons">
    		<SrcDataSource relativeToVRT="1">polygons.csv</SrcDataSource>
    		<GeometryType>wkbPolygon</GeometryType>
    		<LayerSRS>WGS84</LayerSRS>
    		<GeometryField encoding="WKT" field="WKT"/>
    	</OGRVRTLayer>
    	<OGRVRTLayer name="Points">
    		<SrcDataSource relativeToVRT="1">points.csv</SrcDataSource>
    		<GeometryType>wkbPoint</GeometryType>
    		<LayerSRS>WGS84</LayerSRS>
    		<GeometryField encoding="PointFromColumns" x="X" y="Y"/>
    	</OGRVRTLayer>
    </OGRVRTDataSource>
    
    

    Opening the VRT file in as an Import in the Interoperability dialog allows you to specify the Spatial Criteria, Feature Parameters, Import Parameters, and Feature Symbology.  

    When imported, the resulting graphics are native features with business, geometric, and WKT properties.

    If the WKT properties are not desired, disable them in the Import node using the Show Properties > Ungrouped opton.
