Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Linear and angular are the two errors involved in traversing. Hence the following checks are done for angular measurements
|
Angular work |
Checks in angles |
|
Sum of interior angles |
(2N - 4)× 90º |
|
Sum of exterior angles |
(2N + 4)× 90º |
|
Sum of deflection angles |
360º |
|
Fore bearing |
Back bearing ± 180º |
Here N is the number of sides of the traverse
Important Points
- While calculating deflection angles, Right-handed deflection angles are taken as positive and Left-hand angles are taken as negative.
