Description

The vrt created by the tool does not have the

<OGRVRTUnionLayer>

tag that allows load the layers inside the vrt as one unique layer.
It would be nice to have it as option.

example

<OGRVRTDataSource>
<OGRVRTUnionLayer name="UnionedLayer">
<OGRVRTLayer name="caop_2013_costa">
<SrcDataSource relativeToVRT="0" shared="1">/home/giovanni/caop_2013_costa.shp</SrcDataSource>
<SrcLayer>caop_2013_costa</SrcLayer>
<GeometryType>wkbPolygon</GeometryType>
</OGRVRTLayer>
<OGRVRTLayer name="caop_2013">
<SrcDataSource relativeToVRT="0" shared="1">/home/giovanni/caop_2013.shp</SrcDataSource>
<SrcLayer>caop_2013</SrcLayer>
<GeometryType>wkbPolygon</GeometryType>
</OGRVRTLayer>
</OGRVRTUnionLayer>
</OGRVRTDataSource>
