Q: Which among the following condition must be fulfilled by survey stations/survey stations/survey on chain surveying?
  • A. Each portion of Skelton must not be provided with any check lines
  • B. The main lines must pass through each obstacles for better results
  • C. The lines must run through level ground as much as possible
  • D. The main lines should well form well-conditioned squares.
Correct Answer: Option C - The following conditions must be fulfilled be fulfilled by survey stations/survey lines on chain surveying:– • The survey stations should be so selected that survey stations are mutually visible, and this can be achieved if the lines run through the level ground as much as possible. • The main lines should form well conditioned triangles. • As far as possible, the main survey lines should not pass through the obstacles to avoid interruption to chaining and ranging. • The sides of the larger triangles must pass close to boundary line. • The triangles must be properly defined with no angle less than 30⁰& not more than 120⁰. • If possible, a line through the whole length of the area should be drawn.
