I am trying to convert polygon to raster. The polygon class are from 0 to 4. There are many spot that no polygon. It means, I don't create polygon. I try use QGIS, using Raster > Conversion > Rasterize. The result is 0 to 4, but the spot with no polygon is also 0. How to set no polygon to nodata like in : https://github.com/remicres/otbtf_tutorials_resources/blob/master/01_patch_based_classification/tokyo_dataset/terrain_truth/terrain_truth_epsg32654_A.tif

How can I create that using open source software?

Specify an output nodata value that is something other than 0-4 as the default is 0. See the help for the NoData parameter:

Assign a specified nodata value to output bands Default: 0.0
