Introduction
Surveying is the process of determining relative positions of different objects on the surface of the earth by measuring horizontal distances between them and preparing a map to any suitable scale.
Principles of Surveying
1. Location of a point by measurement from two points of reference: According to this principle, the relative position of a point to be surveyed should be located by measurement from at least two points of reference, the positions of which have already been fixed.
Working from whole to part According to this principle, it is always desirable to carryout survey work from whole to part. The idea of working this way is to prevent the accumulation of errors and to control and localize minor errors which, otherwise, would expand to greater magnitudes if the reverse process is followed, thus making the work uncontrolled at the end.
Method of Surveying in Civil Engineering Primary types of Surveying are:
• Plane surveying • Geodetic surveying
