1. Triangulation Surveys

Triangulation surveys are fundamental in establishing accurate controls by utilizing trigonometric principles to calculate sides from measured angles. Various triangulation systems and methods, including trilateration, enhance the precision of these surveys. The chapter covers the principles of triangulation, its application in determining geodetic controls, and the factors influencing station selection for measurement quality.
