Question

Which type of error is represented by a closed traverse, if the algebraic sum of latitude of all the lines is zero?

• A. Positive error
• B. Negative error
• C. No error
• D. Compensating error

Answer 1

The correct option is C No error

• In a closed-loop traverse for no error, the following two conditions should be satisfied :

1. The algebraic sum of all the latitudes should be equal to zero. $\therefore \sum L=L_1+L_2+....=0$ In other words, the arithmetic sum of northing should be equal to the arithmetic sum of southing.
2. The algebraic sum of all the departures should be equal to zero. $\therefore \sum D=D_1+D_2+....=0$ In other words, the arithmetic sum of eastings should be equal to the arithmetic sum of westings.
