Chapter 6 Theodolites
The main function of theodolite is to measure angles in the horizontal and vertical planes. It
is deemed as the scientifically most precise and versatile surveying instrument use

Horizontal Control Surveys
One of the first steps in construction project is to establish a network of both vertical and
horizontal control points on or near the ground in the vicin

(Taping and offset surveying)
The method of tape surveying is often referred to as chain surveying, deriving its name from the
fact that the principal item of
Chapter 4 Angle and Directions
One of the basic purposes of surveying is to determine the relative positions of points on or
near the earths surface. Assigning coordinates to a given point is a useful

Introduction of Basic Surveying
What is Surveying?
Surveying has to do with the determination of the relative spatial location of
points on or near the surface of the earth. It is the art of

1.) The length of a line measured with a 30m long tape was 368.64m. The tape was standardized at a
temperature of 20C. If the temperature during measurement was 42C, find
