Is there a way to set all the 0 value pixels on a raster to nodata using GDAL?

I would like to use fillnodata to fill some holes, but holes are set to 0, so I need to delete them first


You could try something like this with gdal_translate

gdal_translate -of GTiff -a_nodata 0 input.tif output.tif

with gdal:

  1. gdalbuildvrt -of GTIFF -srcnodata 0 input.tif myVrt.vrt
  2. gdal_translate -of GTIFF -scale -a_nodata 0 myVrt.vrt output.tif

beside this you can use raster calculator plugin or grass in qgis too. and arcpy SetNull method.
