Trigonometric Leveling
The process of leveling in which the elevation of point or the difference between
points is measured from the observed horizontal distances and vertical angles in
the field is called trigonometric leveling.
In this method, trigonometric relations are used to find the elevation of a point
from angle and horizontal distance so, it is called as trigonometric leveling. It is
also called as indirect leveling.
Barometric Leveling
Barometer is an instrument used to measure atmosphere at any altitude. So, in
this method of leveling, atmospheric pressure at two different points is observed,
based on which the vertical difference between two points is determined. It is a
rough estimation and used rarely.
