The Total Station (TS) based survey was conducted for measuring the spot levels/land levels of the Pourashava (Northing, Easting, Elevation or RL). Later on the spot level uses for generating contour of the Pourashava. The spot level of land considers 10 meter intervals. Total 16808 nos. spot values collect for the study. Lowest spot height is 0.19m and the highest is 2.58 m. Average height of land shows 1.15 m. Statistical summary of land level presents in the following Table.
Table: Spot Value and Spot Unit
| SL. No | Spot Unit | Value |
| 1 | Total Spot Number | 16808 |
| 2 | Average Height (Meter) | 1.15 |
| 3 | Maximum Height (Meter) | 2.58 |
| 4 | Minimum Height (Meter) | 0.19 |
| 6 | Standard Deviation | 0.49 |
| 7 | Total No of Contour Line | 735 |
