TP3 TP4 BMB BM A TP1 TP2 Exercise: A loop differential leveling circuit began on BM A (elevation 33.851 m) with two turning points in the forward run toward the unknown benchmark BM B and two turning points in the backward run toward the starting benchmark BM A. Backsight and Foresight distances were kept approximately equal. Find and adjust the final elevations of TP1 to TP4 and BMB.
