There are only 15 hill levels (the original game had but 3 remember!) so the only way one can do it is to "smooth" the real terrain heights to fit into the 15 levels, with level 0 being major water (sea, lakes etc). Level 0 is the "16th" level.

It will be up to the map designer to decide if certain bits of the higher ground, especially slopes are to be perhaps rough or even impassable. I used a lot of impassable for the escarpment in my scenario #428 in WW2 "Operation Brevity".
