gdalbuildvrt

Build Virtual Datasets from a list of existing datasets. More information: https://gdal.org/programs/gdalbuildvrt.html.

• Make a virtual mosaic from all TIFF files contained in a directory:
  gdalbuildvrt {{path/to/output.vrt}} {{path/to/input_directory/*.tif}}
• Make a virtual mosaic from files whose name is specified in a text file:
  gdalbuildvrt -input_file_list {{path/to/list.txt}} {{path/to/output.vrt}}
• Make an RGB virtual mosaic from 3 single-band input files:
  gdalbuildvrt -separate {{path/to/rgb.vrt}} {{path/to/red.tif}} {{path/to/green.tif}} {{path/to/blue.tif}}
• Make a virtual mosaic with blue background color (RGB: 0 0 255):
  gdalbuildvrt -hidenodata -vrtnodata "{{0 0 255}}" {{path/to/output.vrt}} {{path/to/input_directory/*.tif}}
