I am trying to export a DEM raster as a 16 bit image using the Raster>Conversion>Translate drop down menus in QGIS. I have seen somewhere I need to save it with a -ot tag to turn it into a 16 bit image but I cannot work out how to do that. If I type in -ot into the end of the output file name it does not work . I know I am not getting it.

Alternatively, how do I do it via command line?

  • The Translate tool that you are using has a drop down menu for "Output data type". The default is "Use Input Layer Data Type" but you want to select "Int16".
