Geodetic Surveying
Definition of geodetic survey: a survey of a large land area in which corrections are made for the curvature of the earth's surface.
# The surface of the earth is not plane but spheroidal.
# Therefore, the line connecting any two points on the earth's surface is not a straight line but a curve.
# The surveying in which curvature of the earth is taken into account for all measurements is known as geodetic survey.
# It possess a high degree of accuracy.
# It is also called trignometrical surveying.
