Important terminologies in surveying and leveling
Leveling stands for the method of finding out the relative elevations of several objects or factors in the world's surface. It's miles completed by using selecting up measurements in the vertical aircraft. A leveling instrument known as ?Level? And ?Staff? Is appointed for this motive in conjunction with different equipments.
Some vital terms in Surveying and Leveling
Level Surface: It refers to a surface that is normal to the direction of gravity at all points as stated by a plumb line. As for instance, the surface of a still lake can be a level surface.
Since the earth is an oblique spheroid, a level surface should not belong to a plane but should be a cursed one. The distance of each point on a level surface is equal from the center of the earth.
Level Line
A level line belongs to a line that is laid on a level surface. It is normal to the plumb line at all points.
Horizontal Plane
A horizontal plane through a point refers to a plane peripheral to the level surface at the point. It is normal to the direction of gravity at that point.
Horizontal Line
A line that remains at a 90 degree angle to the plumb line and tangent to a level surface is called a horizontal line.
