Leveling is the most generally utilized technique for getting the elevations of ground points comparative with a reference datum and is normally done as a different system to those utilized in fixing planimetric position. Thefundamental idea of leveling includes the estimation of vertical separation comparative with a horizontal line of sight. Consequently, it requires a graduated staff for the vertical estimations and an instrument that gives a horizontal line of sight.
The different types of Leveling in ground survey are:
a. Precise or Geodetic Leveling
b. Ordinary or Simple Leveling
Techniques for Leveling
Techniques for leveling might be immediate, for example:
1. Simple Leveling
2. Differential Leveling
3. Profile Leveling
4. Cross Sectioning
5. Reciprocal Leveling
6. Precise leveling
7. Check Leveling
8. Fly Leveling
Or then again might be aberrant, e.g.
1. Trigonometric Leveling
2. Barometric Leveling
3. Hypsometry
