Hi all, I am trying to merge 4 rasters containing nodata pixels using gdal_merge in a single file with separate bands. I use -9999 as nodata value.
In the output file, the first band has the correct nodata pixels (-9999) but the following 3 bands have some zeros, in pixels that were nodata in the input file. My command line: gdal_merge.py -o out.tif -separate -n -9999 -a_nodata -9999 -ot Float32 b1.tif b2.tif b3.tif b4.tif My issue seems to resemble this issue: https://gis.stackexchange.com/questions/190715/gdal-merge-stacking-files-nodata-value-wrong Is this a bug or am I doing something wrong?
