Q: The method of reciprocal ranging can be used in which of the following cases?
  • A. Obstacle to chaining but not ranging
  • B. Obstruction by a building
  • C. Obstruction by a river
  • D. Obstacle to ranging but not chaining
Correct Answer: Option D - The method of reciprocal ranging can be used in obstacle to ranging but not chaining. • When end station is not visible due to there being high ground between them intermediate ranging rod is fixed of the line in a direct way, this method is indirect ranging reciprocal ranging. Note: Ranging Rod size, about 2m long & 4cm thick.
