Executing the below command has successfully converted a multi-band rasterFile into a multi-column CSV file.

      gdal2xyz.py -band 1 -band 2 ... -band 9 rasterFile csvFileName.csv

csvFile generated:

How can I convert this multi-column CSV data back into a multi-band raster image? I prefer Python, GDAL, and command-line solutions.

  • With command line utilities, I fear in no way. The gdal2xyz.py is an alternative for the xyz driver that supports only one band gdal.org/drivers/raster/xyz.html but a script for the opposite direction does not exist. A tedious workaround is to split the CSV into several single band XYZ files by copying the first two columns and the corresponding band columns into each file.
