Q: Most important factor, out of the following, in selecting a triangulation survey station is
  • A. distance between the two station
  • B. intervisibility
  • C. intervisibility and well conditioned triangle
  • D. accessibility and distance
Correct Answer: Option C - Conditions to be fulfilled by survey stations or survey line– • Survey stations must be mutually visible. • The survey line should be taken through fairly level ground. • The stations should be selected in such a way that well-conditioned triangles may be formed. • The framework must have one or two base lines. • The longest of the main survey lines is considered the base line. • The lines must run through level ground as possible Note:-most important factor in selecting a survey station is intervisibility and well conditioned triangle.
