Surveying is the art of making measurements of objects on, above or beneath the ground to show their relative positions on paper. The relative position required is either horizontal, or vertical, or both. Less precisely the term Surveying is used to the measurement of objects in their horizontal positions. Measurements to deteremine their relative vertical positions is known as levelling.

Chain survey is suitable in the following cases: (i) Area to be surveyed is comparatively small (ii) Ground is fairly

As stated earlier a bearing of a line is the angle made by the line with respect to a reference
A number of the techniques discussed in Chapter 3 require the measurement of angles, to a greater or lesser degree
10.1 Introduction The term adjustment suggests that some form of cheating might take place during the process of converting surveying
Advantages are 1. Possibility of omitting measurement is eliminated. 2. The surveyor can compare the plotted work in the field
