Honestly the outputs still look a bit ropey - would love some interesting patches to make the DEM's produced look more natural, with pronounced mountain ranges etc.
What is the point of this? Random DEMS could be useful for making fantasy maps, testing DEM processing routines, trying out cartographic approaches etc.
Make sure you have GDAL and GDAL Python bindings installed.
You need these pip packages:
pip3 install numpy scipy
./random_dem.py
The GDAL Georeferencing is still broken so it does not open nicely in QGIS.
It seems (thanks Raymond for the hint!) that you can make nice procedurally generated landscapes in Blender:
