I have a DEM raster file that will not export in QGIS or ArcMap, in QGIS I right click, export, save as and the file that loads has nothing that pops on the map, the values listed go from an extreme low number to an extreme high number but nothing pops up on the map. The export takes a while to render but nothing shows up.
I also cannot clip it, georeference it, use it in raster calculator, or warp it in either program.
What might be the problem and how might it be solved?
(I went back through the code and typed "input file" and output file" so as to simplify and not to give personal info.) when I try to clip it the log messages are as follows:
