Following the steps this tutorial (step 6), I'm trying to change the minimum and maximum values in a raster DEM. The current range is -6.24 to 3074.67, and I need it to scale from 0 to 65535. Unfortunately I can't figure out how to do this!
The most promising tool seemed to be r.rescale from GRASS, but it gave me the following error message:
The default nodata value is present in rasterband <output5219bf1d25af4b58b13ce1baeb6dfcd7> and would lead to data loss. Please specify a custom nodata value with the nodata parameter.
and since I cannot figure out how to set the nodata parameter, this obviously didn't work. Can anyone help me figure out how to rescale this raster, using r.rescale or any other tool in QGIS 3.6.2?
