    Leveling is the process of the determination of the relative altitude of points on the earth's surface. The altitude or height of any points is its distance above the datum surface (Mean sea level i.e. Geoid) which are referred to their respective datum such as spherical and geoidal height. Leveling deals with the measurement in the vertical plane.

    Common Mistakes in Levelling: (i) The levelling staff not being fully extended. (ii) The staff held upside down. (iii) Reading the staff upwards instead of downwards. (iv) Taking reading coincident with one of the stadiahairs (top or bottom) instead of centralhair. (v) Omitting an entry. (vi) Entering a reading in the wrong column.

  • Leveling SpringerLink

    Leveling is a process to determine the vertical position of different points below, on, or above the ground. In surveying operations, vertical elevations and vertical control are generally derived independently of horizontal control. Some modern positioning devices, termed total stations, allow simultaneous determination of spatial coordinates.
