A line of levels 9.36 km is run to check the elevation of BM 2 which been found to be 31.388 meters with BM 1 of elevation at sea level.
A line of levels 9.36 km is run to check the elevation of BM 2 which been found to be 31.388 meters with BM 1 of elevation at sea level. If the backsight and foresight distances are consistently 110 m and 70 m, respectively, determine the corrected elevation of BM 2 considering the effects of curvature and refraction of the earth.
