Question

3 survey crews completed differential level loops. The total distances and misclosures were: Crew 1 : Distance of loop = 896m; misclosure = 0.025m Crew 2 : Distance of loop = 543m; misclosure = 0.016m Crew 3 : Distance of loop = 761m; misclosure = 0.024m

alculate the maximum 3^rd order allowable accuracy for each crew; i) Crew 1 , ii) Crew 2 , ii) Crew 3 , iv) which crew did not acceptable 3rd order accuracy for their level loop?   

Answer 1

Dear, Here is the solution of your question.

As none of the crew has acceptable 3rd order accuracy.

(iv) All three crew i.e. crew 1 , crew 2 & crew 3 didn't have acceptable 3rd order accuracy

(i) Maximum Allowable 3rd order accuracy for crew 1 = 11.36 mm or 0.001136 m

(ii) Maximum Allowable 3rd order accuracy for crew 2 = 8.84 mm or 0.000884 m

(iii) Maximum Allowable 3rd order accuracy for crew 3 = 10.47 mm or 0.001047 m.
