Abstract
Surveying has been defined as the science of determining positions of points on the earth’s surface. The four components of surveying measurements are: (1) vertical (elevations), (2) horizontal (distances), (3) relative direction (angles), and (4) absolute direction (azimuths). Due to recent developments in technology, the accuracy and efficiency of measuring these first three components have increased dramatically. This has resulted in accurate determination of the size and shape of figures. Unfortunately, determination of the orientation of figures, the fourth component, has not kept pace, even though inexpensive technology and equipment exist, such as precise timepieces, portable time signal receivers, ephemerides, programmable calculators and computers. The purpose of this chapter is to provide sufficient theory, calculations, and field procedures so surveys can be accurately oriented without significant increases in time and expense.
