👉Types of Leveling
1. Differential Leveling
Used to determine the difference in elevation between two or more points bymoving the instrument.
2. Profile Leveling
Used along roads, canals, or pipelines to determine ground profile along a fixedline.
3. Fly Leveling
Used for transferring a benchmark when high accuracy is not required.
4. Reciprocal Leveling
Used when leveling across obstacles like rivers to eliminate errors.
5. Trigonometric Leveling
Used when distances are long; elevation is calculated using vertical angles.
6. Barometric Leveling
Uses atmospheric pressure differences; not very accurate.
7. Precise Leveling
High accuracy leveling used for major engineering projects.
