Before survey-grade satellite positioning was available, the most common technique for conducting control surveys was . We also use content and scripts from third parties that may use tracking technologies. Other survey methods may still be acceptable, but RTK has been found to be the most efficient method. Surveying is the process of determining relative positions of different objects on the surface of the earth by measuring horizontal distances between them and preparing a map to any suitable scale. One method for measuring elevation is to use differential leveling. 3.2 Definitions Differential levelling is the term applied to any method of measuring directly with a graduated Boning rods and travelers. Control survey: used to reference preliminary and layout surveys. Horizontal control: arbitrary line tied to property line or HWY center or coordinated control . Establishing horizontal control. A critical aspect of this type of work is developing horizontal and vertical positions of these control points relative to a desired horizontal .
