Q: Up to what amount of area Plane surveying is done?
  • A. 800 sq. km
  • B. 1000 sq. km
  • C. 260 sq. km
  • D. 560 sq. km
Correct Answer: Option C - The curvature of the earth surface is taken into account is called geodetic survey. • Involve large are more than about 260 km2 • Higher degree of accuracy the earth surface is assumed to be spherical i.e. three dimensional. • If induces small area less than about 260 km2 that's called plane surveying the earth surface is assumed to be plane i.e. two dimension and lower degree of accuracy.
