- A win python program (https://winpython.github.io/) consisting of 3 modules dmr_mg.py and the 2 library MODULEs dmr_data_headers, & dmr_myf.py.
- 2-d DEM optimization method presents an alternative to DEM comparison by elevation differences modeling. In it's general version (3.d, 4.d etc., etc.) is not limited to the comparison/evaluation of only 2 DEMs but can handle 3 DEMs, 4 DEMs at the same time, etc. etc.
