DISCUSSION
2 On the Booking Sheet also show how you could check your work.
Total of back sites and total of foresights have been calculated. The difference between total fore sights and total back sights should equal to the difference between reduced levels of starting point and end point of levelling exercise. Calculation is done in the booking sheet.
3 Please state if the Levelling work is of sufficient accuracy, and why, giving reason for how this level of accuracy could have been achieved (either positive or negative).
Levelling work is up to sufficient accuracy. The difference between total fore sights and total back sights is equal to the difference between reduced levels of starting point and end point of levelling exercise.
4 Explain how you would complete a field survey using an Automatic level.
â€¢ Conceptually map cross-sections or points you need for the study. This is initial planning of the survey work

3. Please state if the Traverse is of sufficient accuracy, and why, giving reason for how this level of accuracy could have been achieved (either positive or negative).
The allowable maximum angular misclosure depends on the purpose of the survey as given in the Table 4.
If the precision of the survey is fourth order, the error is within the limit. However, if the precision is geodetic, secondary or tertiary, the error is out of the limit. Then these readings cannot be used. The traverse survey should be repeated to get accurate results.
The allowable maximum error can be achieved easily by levelling the Total station on the station correctly. When handling the Total station, anyone should be careful to check whether the instrument is levelled on the ground.
Even though the line lengths of the traverse polygon are measured, it cannot be checked for correct lengths because of the lack of a bearing measurement. Measuring the Whole Circle
