1. Triangulation :
Triangulation is nothing but the system consists of not of interconnected triangles. In this method, knowing the length of one side and three angles, the length of other two sides of each triangle can be computed.
2. Satellite Station :
A subsidiary station is established as near the true or principal station as possible, the station so established
is called a satellite station or eccentric station or false station.
3. Reduction to centre:
If the true station were occupied by computing the corrections and apply them algebraically to the observed
values is generally known as reduction of centre.
4. Base net:
A series of triangles connecting the baseline to the main triangulation is called base net.
5. Bench marking :
It is a fined reference point of known elevation.
6. Types of Bench Mark:
Great Trigonometric survey Bench mark
Permanent Bench mark
Arbitrary Bench mark
Temporary Bench mark
7. Equipments used for base line measurement:
Marking stakes or tripod
Supporting stakes or tripod
Six number of thermometer.
8. Signals :

9. Mistakes (or) Gauss Errors:
