Occasionally I encounter a set of grading plans with nothing but contour lines as a guide to building a site. Seldom, if ever, does contour lines provide sufficient data to properly establish an accurate DTM from which to work. Allow me a chance to illustrate:
Looks simple and straightforward does it not, put a little more [...]
