Geodetic triangulation is an efficient and accurate method of establishing control points over extensive
areas of the earth's surface. In the past, as well as in many surveys today, triangulation and traverse have
formed and do form the basic horizontal-control networks throughout the world. In geodetic
triangulation, the survey and the computations start with a baseline whose length and azimuth are
determined to a specified accuracy. This lesson will cover horizontal measurements in detail, to include
methods of taking measurements, the types and characteristics of the instruments used and how they are
read, and how the information is recorded in the field.

3-1. Baseline Measurement. The measurement of an accurate baseline is necessary. Baselines are
generally about one-sixth to one-fourth the length of the
