Plane Surveying: The type of surveying in which the mean surface of the earth is considered as a plane, or in which its spheroidal shape is neglected, with regard to horizontal distances and directions. Land surveyors measure horizontal positions in geographic or plane coordinate systems relative to previously surveyed positions called control points, most of which are indicated physically in the world with a metal benchmark that fixes the location and, as shown here, may also indicate elevation about mean sea level (Figure 5.10).

Horizontal control network may be established by one of the following methods: traversing, triangulation, trilateration, GPS, photogrammetry. 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.
