,1. CONCEPT OF GEODETIC SURVEYING.
, Introduction
Definitions
Geodesy is the science of the measurement and representation o
shape, size and distribution of the earth and its gravity field in 3-
time-varying space.
It deals with determining:
▪precise positions on the surface of Earth,
▪the size and shape of Earth,
▪the motions of Earth in space, and
▪the gravity field of Earth.
, Introduction Contd
Geodetic Surveying
▪ Is the science of locating and relating the position of ob
on the earth relative to each other, while taking into acc
the size, shape and gravity of the earth.
▪This type of survey is suited for large areas and long line
▪it is used to find the precise location of basic points nee
for establishing control for other surveys.
