Method Of Work.

1. Set up the theodolite over first station .

2. Set 0 00' 00" at first point . Turned the theodolite to the next station .Find the angle every station .

3. Recording show data in sketching plan .

4. Taping distance point by point .

5. Sketching picture of working area from received data .
