Errors in surveying

An error in surveying is defined as the difference between two or more values of an identical quantity. However, the estimates are never accurate and there will always be a degree of variability regardless of the research tool or method used. These differences are known as errors that need to be reduced or eliminated to maintain certain levels of accuracy. Even if you carefully follow the prescribed test procedures, the considerations may contain errors.

**Running Leveling Circuit Analysis**

**Introduction**

Consider the following running leveling circuit (Figure 1).

**Figure 1: Differential Leveling**

The diagram depicts a leveling circuit with four points: A, B, C, and D. The distances between these points are as follows:

- A to B: 500 m
- B to C: 350 m
- C to D: 400 m
- D to A: 250 m

**Survey Results**

The elevation of point A is given as \( H_A = 100 \, \text{m} \). Table 1 presents the results of a leveling survey conducted on this circuit.

**Table 1: Survey Results**

| | BS | HI | Fs | Elevation | Distance | Correction | Adj* Elev |
|-----|-------|--------|--------|-----------|----------|------------|-----------|
| A | 1.555 | | | 100.000 | 500 | | |
| B | 2.100 | | 0.335 | | 350 | | |
| C | 1.800 | | 1.564 | | 400 | | |
| D | 3.325 | | 2.647 | | 250 | | |
| A | | 4.056 | | | | | |

**Tasks**

1. Calculate the elevations of the different points in the table.
2. Calculate the misclosure error using the compass method.
3. Calculate the adjusted elevations of the different points.

This exercise involves understanding the differential leveling process and applying corrections to achieve accurate adjustments for each point's elevation.

13. A surveyor needs to determine the coordinate of an inaccessible location, point C. Setting up on point A, they sight point B (due east of point A) and set 0 on their total station. The measured distance between A and B is 400 m. The surveyor points the total station at point C (north of point B and east of point A) and reads an angle to the right of 340°20'15". Given that the UTM coordinate of point A is 680100.455 mE, 4912081.750 mN (UTM 17T, NAD83) what are the coordinates of points B and C?
