I'm trying to merge large raster files (DEM's) together but I run into memory errors using the 'Raster Merge' tool in QGIS 3.8.
I suspect the issue is mainly the high amount of precision in the float32 data format for each pixel. Therefore if I could translate/convert the format into half/float16 format I should be able to do this.
Unfortunately I don't see an option to export GeoTIFF's into this format in the 'Raster Translate' tool or otherwise.
Edit: I need a few decimal places of precision - ideally 3. The rasters are DEM's that are accurate to about 8-10cm, so any decimals past 3 are nonsense and just eat up memory.
