SAGA-GIS Tool Library Documentation (v7.8.2)

Tool Import from Virtual Raster (VRT)

The tool allows one to clip / extract a raster subset from a virtual raster dataset (VRT). Such a VRT is actually an XML based description of a mosaic of raster datasets and can be created with the "Create Virtual Raster (VRT)" tool.
