    THEODOLITE SURVEYING THEODOLITE The Theodolite is a most accurate surveying instrument mainly used for: • Measuring horizontal and vertical angles. • Locating points on a line. • Prolonging survey lines. • Finding difference of level. • Setting out grades • Ranging curves • Tacheometric Survey 4. Adjustment Adjustments should be made at regular intervals and particularly before work on any control survey is started. Such adjustments should be made under the most ideal conditions available, normally in the highway yard or shop. Adjustment should be done in accordance with the user’s manual of the specific instrument.

The use of levels and total stations is illustrated by a series of practical examples. In addition, applications programs are described; these are incorporated into the modern total stations manufactured by Leica Geosystems and they solve survey tasks even more easily and elegantly.

Surveying manual Surveying is the science of determining the relative positions of objects or points on the earth’s surface.

These points may be any physical thing: a highway, culvert, ditch, storm drain inlet, or property corner. Distances and directions determine the horizontal positions of these points.

Carrying out a level traverse. To determine the difference in level between points on the surface of the ground a 'series' of levels will need to be carried out; this is called a level traverse or level run. Leveling or Field Procedures. The leveling or field procedure that should be followed is shown in Figure 1 below.
