Leveling requires equipment such as leveling staff, tripod, auto level meter, staff bubble and measuring tape. Leveling method is now widely used in construction sites. Leveling is an inexpensive, simple and accurate method for measuring height. Besides construction site, leveling are also used for measurements of rivers or lake.
Levelling is the art of determining and representing the relative heights or elevations of different points on the surface of earth. Surveying deals with the position of points in the horizontal plane whereas Levelling

A theodolite works by combining optical plummets (or plumb bobs), a spirit (bubble level), and graduated circles to find vertical and horizontal angles in surveying. An optical plummet ensures the theodolite is placed as close to exactly vertical above the survey point. The internal spirit level makes sure the device is level to to the horizon. The graduated circles, one vertical and one

Levelling. Levelling is the general term applied to any of the various processes by which elevation are determined. It is a vital operation in producing necessary data for mapping,
The art of determining relative altitudes of points on the surface of the earth of beneath the surface of earth is called LEVELLING. For execution of Engineering Projects it is very necessary to determine elevations of different points along the alignment of proposed project.
Grid leveling is used for site investigation, for drawing contour lines and for the easy calculation of volumes. The opposite figure shows a typical survey of a site using grid point levels. The area of the site is divided into a number of squares 5 × 5 metres (triangles or rectangles can also be used) and levels are taken at corner points.
