Everytime with every function (e.g convert data storage type or gdal-translat -ot Byte) the output is a completely white map with a black border. only the "save as" export works, but the TIFF also has 3 bands and the data is much bigger..this isnt my intention

Has anybody an idea?

    Show gdalinfo -stats reports from the original and converted. Put a sample image to play with somewhere for downloading if you have right to do it.

  • what is the range of your input values ?

  • value range of the input scene is 0 - 25480.812476 value range of the wrong created 8 bit is 0 - 255 enclosed u will find a link which contais the 16 bit single-band (free content): file-upload.net/download-9541350/…

  • Try adding -scale src_min src_max in gdal_translate code. src_min and src_max values based on yours 16bit raster value range will be needed to scale down to 8bit (see detailed description: gdal.org/gdal_translate.html)

  • ive tried this and fortunatly the output has had the correct value range 0-255 + -ot byte command i have now the result i wanted to have. thanks!

Lets have a close look at statistics about scene enclosed by you:

C:\Program Files\QGIS Chugiak\bin>gdalinfo C:\Users\Janek\Desktop\LC819402420142
48LGN00_B5.TIF -stats


    STATISTICS_MAXIMUM=65535 - this especially!


    STATISTICS_MINIMUM=0 - and this one


... and histogram:

enter image description here

Having it's real values in much narrower range - to perform raster conversion you should force scaling in gdal_translate

Add -scale src_min src_max in gdal_translate code src_min and src_max values based on yours 16bit raster real value range, and -ot Byte to force 8bit value type. To omit no data areas add also a_nodata 0.

Try something like this:

    You can alway process each band separately (for gdal_translate add flag -b to select given band e.g. -b 1) then you can merge bands back to a single raster (e.g. via vrt format or using gdalmerge)
