Only in the roughest sense. It boils down to about five levels of discrete elevation. I'd make a new one with continuous tone if I were going to model it.
Do you have a contour map of the area?
For the record... This was an EXCELLENT post. Thanks for the information keithcurtis.
A lot of very good information.
