If D M D's are computed beginning at the most westerly point in the traverse , all D M D's will be positive . The last column of positive and negative double areas is found by multiplying each D M D by its corresponding latitude .
Coordinates of the corners are computed in ordinary manner by noting bearing and distance of each from nearest , or most accessible , traverse station , of which the coordinates are ascertained by method previously described .
by sighting on a traverse line with the lower motion ; set the horizontal vernier to read the computed bearing or ... From an underground station near the winze or raise , measure bearings and distances to the corners , and compute ...
