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
Input Data - Elevation
COMMAND

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
