Q: Compass surveying is useful compared to chain surveying when:
  • A. Uneven terrain needs to be surveyed
  • B. A small area needs to be covered in great detail
  • C. Chain survey tools are not available
  • D. A large area needs to be covered
Correct Answer: Option D - Compass surveying–Compass surveying is the branch of surveying in which the position of an object is located using angular measurements determined by a compass and linear measurements using a chain or tape. • Compass survey is done for large areas. Chain surveying– • The measurements in chain surveying are linear • It is used when plans are required on large scale • The area shall be fairly small • Accuracy is low.
