Work out the coordinates (N & E) of a station (C) from the designated control stations (A, D) with known coordinates (N & E). This is to be carried out following a designed route and using the closed line traversing method. Coordinates (N & E) of the start station and the end station are given in the table. Coordinates of the Start Station A Coordinates of the Reference Station B Coordinates of the End Station D E (m) 65328.112 65336.961 65428.049 N (m) 40343.429 40378.297 40392.799
