Q: Which of the following statements are true with respect to working from whole to part? i. Major control points are established first with higher precision and then the minor control points are established using less precision. ii. Major control points are established first with higher precision and then the minor control points are established using higher precision too. iii. Errors are minimized. iv. Less number of instruments are required for surveying.
  • A. i and iii
  • B. ii and iv
  • C. ii, iii and iv
  • D. i and iv
Correct Answer: Option A - Working from whole to part– • Major control points are selected and measured first with high degree of precision, minor details can be collected later on even with less degree of precision. • The main idea of working from whole to part is to localize errors and prevent their accumulation • Less number of instruments are required for surveying.
