Calculate departures and latitudes

Reference no: EM131147093

The traverse in Problem 10.21 was performed in the Pennsylvania north zone of SPCS83. The average elevation for the area was 367.89 m and the average geoidal separation was -30.23 m. Using the mean radius of the Earth of 6,371,000 m, reduce the observations to grid and adjust the traverse using the compass rule. Assume that the azimuths given in Problem 10.21 are grid azimuths. Compare this solution with that obtained in Problem 10.21.

Problem 10.21:

The following data apply to a closed link traverse [like that of Figure 9.1(b)]. Compute preliminary azimuths, adjust them, and calculate departures and latitudes, misclosures in departure and latitude, and traverse relative precision. Balance the departures and latitudes using the compass rule, and calculate coordinates of
points B, C, and D. Compute the final lengths and azimuths of lines AB, BC, CD, and DE.
