3 : Leveling Methods

Question 1

the most commonly employed method of determining the elevation of points some distance apart by a series of set ups of a leveling instrument along a selected route uses a spirit level

Answer 1

Direct of Spirit Leveling

Question 2

process of accurately determining the difference in elevation between two intervisible points located at a considerable distance apart

Answer 2

Reciprocal Leveling

Question 3

used to determine the difference in elevation between two points by trigonometric computations from measurements of its horizontal or slope distance and the vertical angle between the points

Answer 3

Trigonometric Leveling

Question 4

used to determine differences in elevation between points at designated short measured intervals along an established line to provide data from which a vertical section of the ground surface can be plotted

Answer 4

Profile Leveling

Question 5

combines features of direct leveling with those of trigonometric leveling differences in elevation between points are computed from observed vertical angles and the three intercepts on a rod held at each point backsighted or foresighted

Answer 5

Stadia Leveling

Question 6

determination of differences in elevation between points by measuring the variation in atmospheric pressure at each point by means of a barometer

Answer 6

Barometric Leveling

Question 7

used to obtain a representation of the ground surface on either side of the centerline

Answer 7

Cross-Section Leveling

Question 8

method of determining the relative elevations of points in borrow-pit excavations for the purpose of calculating volumes of earthwork

Answer 8

Borrow-Pit Leveling
