Topo Extended

Calculates more advanced terrain parameters. Uses parameters calculated by topo if available. Based on MacMillans Paper and extending it quite a bit for another 1x parameters. More parameters than shown here are actually calculated. see list at the end.


Input Data - Elevation


Command Call window with stream threshold set to 100 cells

RESULTS -- to be updated as topo_extended calculates now many more parameters

Elevation to nearest pit.. looks bad.. but thats a real life example as only a limited number of pits are identified.

add formula/description and figure for better explanation
