Hello, I have 3 single band GeoTIFF files, with UInt16 data type. I want to merge them in a single GeoTIFF file, with 3 bands, and RGB color interpretation
I've read this http://lists.osgeo.org/pipermail/gdal-dev/2011-April/028451.html So, I tried to do this: gdal_merge.py -separate -co "SAMPLESPERPIXEL=3" -co "BITSPERSAMPLE=16" -co "PHOTOMETRIC=RGB" -o output.tif file1.tif file2.tif file3.tif Of course, it didn't work. All the pixels of output.tif are 0. Reasons: - GTiff does not support BITSPERSAMPLE or SAMPLESPERPIXEL creation options. - This is a guess, but I think PHOTOMETRIC=RGB can't be used with pixels of type different from Byte - ? Another thing I tried was to use gdalbuildvrt, and add color interpretation for bands. No effect. Plus, my original raster files are rotated, and I had to warp them. I shouldn't modify the input data at all. Any clues?
