It can operate on either raster or vector data sources, though the two different datasets cannot be mixed in the same VRT file. VRT driver is a raster format driver that allows a virtual GDAL dtaset to be composed from other GDAL datasets with repositioning and algorithms potentially applied as well as various kinds of metadata altered or added.
