LEVELING INSTRUMENT. A device used in making surfaces level or at right angles to a plumb line. The "leveling instrument" (Heb., mish·qeʹleth or mish·qoʹleth) was employed by carpenters, stonemasons and other craftsmen of ancient times to achieve horizontal accuracy when building walls and various structures, while the plummet was used to assure vertical accuracy.
Simple Leveling It is a simple and basic form of leveling in which the leveling instrument is placed between the points which elevation is to be find. Leveling rods are placed at that points and sighted them through leveling instrument. It is performed only when the points are nearer to each other without any obstacles.
The main pieces of surveying equipment in use around the world are the following: theodolite, measuring tape, total station, 3D scanners, GPS/GNSS, level and rod.
