INTRODUCTION
A Geodetic survey ascertains the definite position of permanent points on the surface of the earth, after considering the shape, size, and curvature of the earth. Geodetic surveying is the survey in which the curvature of the earth is taken into account and a higher degree of accuracy in linear and angular observations is achieved. The geodetic surveys stretch beyond large areas and lines attaching any two points on the surface of the earth are treated as arcs. For evaluating their estimated distances on the plans or maps, the rectifications for the earth’s curvature is obtained to the measured distances. The angles between the curved lines are considered as spherical angles. The knowledge of spherical trigonometry is required for making measurements in relevance to geodetic surveys.

Geodetic surveying methods are connected when zones or separations included are great to the point that coveted exactness and accuracy results can’t be acquired by conventional or plane looking over. Geodetic estimations are presently being finished with the utilization of circling satellites that are situated 12,500 miles over the surface of the earth.

SCOPE AND USE OF GEODETIC SURVEYING
This is the technology of identifying and relating the position of objects on the earth relative to each other while keeping into account the size, shape, and gravity of the earth. Such a survey is best suited for large zones and long lines and is used to locate the exact location of basic points required for establishing control for other surveys.
Practical applications of geodetic Survey include observing the movements of the earth and defining the exact location of points on the surface of the earth, to be used for tracking the satellite and global navigation.
