## Differential Levels ### Table Overview This table summarizes the differential leveling data collected on a specific date. It includes information on the back sight (B.S.), height of the instrument (H.I.), fore sight (F.S.), elevation (Elev.), and adjusted elevation (Adj. Elev.) for various stations (Sta.). The detailed table below helps in determining elevation differences and ensuring accuracy in leveling across different points. | Sta. | B.S. | H.I. | F.S. | Elev. | Adj. Elev. | |-------|-------|----------|-------|----------|---------------------| | BM Mil. | 1.33 | 2054.51 | | 2053.18 | 2053.18 | | TP1 | 0.22 | | 8.37 | 2046.14 | 2046.14 (-0.004) | | TP2 | 0.96 | 2046.36 | 7.91 | 2038.45 | 2038.44 (-0.008) | | TP3 | 0.46 | 2039.41 | 11.72 | 2027.69 | 2027.68 (-0.012) | | BM Oak | 11.95 | | 8.71 | 2019.44 | 2019.42 (-0.016) | | TP4 | 12.55 | 2031.39 | 2.61 | 2028.78 | 2028.76 (-0.022) | | TP5 | 12.77 | 2041.33 | 0.68 | 2040.65 | 2040.62 (-0.026) | | BM Mil. | | 2053.42 | 0.21 | 2053.21 | 2053.18 (-0.030) | ### Page Check Calculation This calculation ensures the accuracy of the recorded data: \[ \text{Page Check:} \\ 2053.18 \\ + 40.24 \\ = 2093.42 \\ - 40.21 \\ = 2053

### Differential Leveling Table Below is a transcription of a differential leveling table used for surveying elevations. | Station | Back Sight (BS) | Height of Instrument (HI) | Fore Sight (FS) | Elevation (Elev.) | Adjusted Elevation (Adj. Elev.) | |---------|-----------------|--------------------------|-----------------|-------------------|--------------------------------| | BMwater | 4.54 | | | 100.00 | | | TP1 | 5.38 | | 5.13 | | | | TP2 | 5.04 | | 6.80 | | | | BMstone | 5.49 | | 5.46 | | | | TP3 | 6.28 | | 5.24 | | | | TP4 | 4.93 | | 5.66 | | | | BMwater | | | 3.71 | | | **Explanation of Columns:** 1. **Station (Sta.):** The specific point where measurements are taken. Examples include benchmark water (BMwater), turning points (TP1, TP2, etc.), and benchmark stone (BMstone). 2. **Back Sight (BS):** A reading taken on a leveling rod held at a point of known or assumed elevation. 3. **Height of Instrument (HI):** The height of the leveling instrument above a chosen reference point. 4. **Fore Sight (FS):** A reading taken on a leveling rod held at an unknown point to determine its elevation. 5. **Elevation (Elev.):** The calculated or known elevation of the station point. 6. **Adjusted Elevation (Adj. Elev.):** Adjusted elevation values after calculations. The table is used by surveyors to record and process elevations for accurate mapping and construction planning. Actual elevation values are recorded along with readings from the leveling instrument to calculate the desired values. In this table, some fields are not filled out, indicating stages of measurements or calculations that may be pending.
