Century Dictionary and Cyclopedia

  1. n. The act or process of reducing an uneven surface to a level or plane.
  2. n. The art or operation of ascertaining the different elevations of objects on the surface of the earth; the art or practice of finding how much any assigned point on the earth's surface included in a survey is higher or lower than another assigned point. It is a branch of surveying of great importance in making roads, determining the proper lines for railways, conducting water, draining low grounds, rendering rivers navigable, forming canals, and the like. The instruments commonly employed are a level or leveling-instrument and a pair of leveling-staffs. One of the staffs is held up vertically, resting upon the ground at the initial point. The observer then goes forward with his instrument for a convenient distance, makes his telescope level, and directs the rod-man to raise or lower the target until it is at the height of the telescope. This is called a backsight. The height of the target on the rod is now read. The other rod has meantime been carried forward, and is observed in the same manner. This is called a fore-sight. The instrument is now carried forward and a back-sight is made on the last rod. When a bench-mark or other terminus is reached, all the fore-sights are added together, as well as all the back-sights, and the difference of the sums is the difference of elevation.
