The data of a closed traverse is shown below. Complete the table below and determine the area using DMD method.
Control surveying is referred to as the determination of the precise position of a number of stations which are distributed over a large area. Control surveys are usually divided into main and auxiliary controls primary and secondary controls horizontal and vertical controls high precision and low precision controls
1. Given the following tabulations are observed and calculated data for a traverse. Balance the latitudes and departures by the COMPASS RULE and compute for the area of the closed traverse by DOUBLE PARALLEL METHOD (DPD). Tip: Before you compute for the area of the closed traverse, you must first adjust the latitudes and departures.
