Document Summary

A graph or (cid:471)d slice of a topological map to identify elevation changes across a line. Method (cid:470)(cid:511) easier, but impossible to change horizontal scale (cid:470). Take a piece of paper, and line it up with the line (cid:470). Take a ruler and measure the distance between each change and the beginning of the line (cid:471). Multiply this distance by the scale and put that on your graph. Ivers are assumed to be very shallow; just put a little bump. Contour lines can never cross, except where an overhanging slope exists. Universal transverse mercator coordinate system (cid:539)utm(cid:540)(cid:511) six digits(cid:511) eeennn first three digits being the (cid:520) asting(cid:521) line immediately west of feature in question last three digits the (cid:520)northing(cid:521) line immediately south of feature in question.
