Re: [otb-users] introduction of negative DNs in otb
Hi Gabrielle, Actually OTB does not support half precision floating point... It will be read as a 32bits floating point. The negative value can come from a No Data in your images, as you are interpolating values... As a workaround you can try to use DynamicConvert (to be sure that it is not the conversion from 16 to 32 bits that is not done correctly), and then use a mask to avoid taking No Data into account (for instance set a No Data Value to -99, with the ManageNoData app, and threshold the result once interpolated to only keep positive values). Hope it works, and don't hesitate if you have more questions! Antoine On 11/01/2019 16:30, Gabrielle Hoelzle wrote: I have not been using command line but a script. I will attach.

Hi, You can set the output encoding with : https://www.orfeo-toolbox.org/PythonDoc/stubs/otbApplication.Application.html#otbApplication.Application.SetParameterOutputImagePixelType SetParameterOuptutImagePixelType(“out”, 2) should set it to unsigned int (16 bits).
