Question

The azimuth from station A of a link traverse to an azimuth mark is 212°12'36". The azimuth from the last station of the traverse to an azimuth mark is 192012'16". Angles to the right are observed at each station: A = 136°15'40", B = 119°15'36", C = 93°48'54", D = 136°04'16", E = 108°30'10", F 42°48'02", and G 63°17'16".

a. What is the angular misclosure of this link traverse?
b. What FGCS order and class does the traverse meet?

Answer 1

The angular misclosure of the link traverse can be calculated by finding the difference between the sum of the observed angles and the sum of the calculated angles. The FGCS order and class of the traverse cannot be determined without specific survey requirements.

Step-by-step explanation:

The angular misclosure of a link traverse is the difference between the sum of the observed angles and the sum of the calculated angles. To find the angular misclosure, we need to calculate the sum of the observed angles and the sum of the calculated angles. The sum of the observed angles is the sum of angles A, B, C, D, E, F, and G. The sum of the calculated angles is the azimuth from station A to the azimuth mark plus the azimuth from the last station to the azimuth mark. Subtracting the sum of the calculated angles from the sum of observed angles gives us the angular misclosure.

The FGCS (Federal Geodetic Control Subcommittee) order and class of a traverse depends on the survey specifications and the level of accuracy required. Without information on the specific survey requirements, it is not possible to determine the FGCS order and class of the traverse.
