[edit] Build a virtual stack

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 (here: B2,B3,B4,B5,B6,B7,B8,B8A,B11,B12) 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.
  • 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

[edit] Create a new multiband raster file (single bands to multiband)

A multiband file stores several single raster layers in one file.

  • Click Raster --> Miscellaneous --> Merge.
  • 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: 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.
  • Output data type Uint16
  • Output Converted file: Click ... Save to file ..-and choose a new file name with extension *.tif
  • Check the checkbox on Place each input file into a separate band (see screenshot below).
