Q: The position of a point can be fixed more accurately by
  • A. cross-staff
  • B. optical square
  • C. oblique offsets
  • D. perpendicular offsets
Correct Answer: Option D - Locating Ground features : offsets - An offset is the lateral distance of an object or ground feature measured from a survey line. • When the angle of offset is 900, it is called perpendicular offset. • When the angle is other than 900, it is called an oblique offset. • The position of a point can be fixed more accurately by perpendicular offsets.
