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 place.

1. Click Raster --> Miscellaneous --> Build Virtual Raster (Catalog).
2. Input files: Click Select and choose several single band raster files by holding Strg + left click. Take care on the order of the file selection: it determines the rank of bands in the resulting multiband file.
3. Output file: Click Select and choose a new file name.
4. Click the checkbox -separate on (see screenshot below).

1. Click OK

Create a multiband raster file (single bands to multiband)

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