A VRT (Virtual Dataset) is a list of links to input raster datasets. This has the advantage that no additional physical copy of the original files is necessary which saves storage capacity.

  • Click Raster --> Miscellaneous --> Build Virtual Raster.
  • Input files: Click Select and click the checkbox of several single raster band files in the Multiple Selection window. Take care on the order of the files selection: etermines the rank of bands in the resulting multiband file. The rank of files can be changed by drag and drop in the Multiple Selection window.
  • Output Converted file: Click ... Save to file ..-and choose a new file name.
  • Check the checkbox on Place each input file into a separate band (see screenshot below).
  • Set output Resolution to highest.
  • Set Resampling algorithm to Bilinear

Take care on the order of the files selection: it determines the rank of bands in the resulting multiband file. The rank of files can be changed by drag and drop in the Multiple Selection window.
