Distance & Angles
Instument
- Theodolite telescope
- Telescope stand
- Tape
Objective
- practicing of Theodolite
- plot of rectangular area by mean of Theodolite & Taping
- dimensions of closed area by law of cosine
 |
1.Specific close taverse loop area.Setup theodolite in area that you can see every angle of close traverse loops (without switch on theodolite) . |
 |
2.Set the theodolite in 00 00' 00" angle at the last left side angle of loop . |
 |
3.Taping distance from theodolite to every angle of loop . |
 |
4.Taking result data to draw out in loop . |
By assumed standard scale for checking error
Error = 1: Original distance / Error distance
Depend on : Error distance = Original distance - Every total plus of all angle in loop .
Accuracy Ratio = 1:5000
