Hi Rick, as Guy already wrote, Gimp 2.8 only supports 8-bit. Gimp 2.10 supports 16-bit as internal format and in the raw loader. And perhaps you are interested, Gimp 2.10 has support for the HGT file format, gathered by the Shuttle Radar Topography Mission (SRTM). I blogged about it here: https://dablogter.blogspot.com/2018/01/gimp-now-supports-hgt-file-format.html
And I have an blogpost how to import the NOAA GLOBE elevation files here: https://dablogter.blogspot.com/2018/09/howto-open-elevation-data-from-noaa.html What is missing is import of 32-bit float values in the "Load Image From Raw Data"-plugin. I opened a feature for that: https://gitlab.gnome.org/GNOME/gimp/issues/2804 Do you have a link to one of thePDS images? Regards, Tobias Am Mi., 30.
