![The image presents a differential leveling exercise from an educational context, specifically focusing on elevation calculations.
**Differential Leveling Exercise:**
1. **Objective:**
- Determine the elevation of each station.
- Given: The elevation of BM 132 is known to be 153.236 m.
2. **Adjusting Elevations:**
- The level run length is 780 m, divided equally among stations.
- Adjust the elevation so the error is evenly spread.
3. **Accuracy Requirement:**
- Evaluate if the survey meets an accuracy ratio of less than 1/3,000.
**Table 2 Overview:**
| Station | BS [m] | HI [m] | FS [m] | Elevation [m] |
|---------|--------|--------|--------|---------------|
| BM 130 | 0.608 | | | 153.285 |
| TP 1 | 1.030 | 1.525 | | |
| TP 2 | 0.482 | | 0.736 | |
| TP 3 | 1.591 | 2.283 | | |
| BM K110 | 2.145 | | 1.885 | |
| TP 4 | 1.997 | 1.735 | | |
| BM 132 | | | 0.321 | |
- **Columns Explanation:**
- **Station:** Designation of the point.
- **BS [m] (Backsight):** Measurement from the previous point to the instrument.
- **HI [m] (Height of Instrument):** Elevation of the instrument calculated from BS.
- **FS [m] (Foresight):** Measurement from the instrument to the next point.
- **Elevation [m]:** Elevation of the point being measured.
4. **Sample Calculation:**
- Elevations are calculated using the formula: Elevation = HI - FS.
- Measurements are adjusted for systematic errors.
Understanding this process is crucial for surveying, ensuring precise and reliable elevation data, essential for construction, mapping, and civil engineering projects.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F244041aa-14a7-461b-8dc7-dc939a310397%2F84b1c077-0fb3-4b2c-a90b-0a701216902b%2F8m04kz_processed.png&w=3840&q=75)
