Horizontal Control Surveys,The purpose of control surveys is to provide a uniform framework of reference for the coordination of all surveying activities within a given area. Control surveys consist of horizontal and vertical controls, which require fundamentally different methods of establishment, although some control points may be common to both control nets.

Vertical Control,Urban planners, public works departments, engineering companies, and those involved in physical changes in a city area must work on a three-dimensional model of the city. Therefore, a knowledge of vertical distances between various points in urban areas is as important as the knowledge of their horizontal position.
