Triangulation Station

 

(also triangulation point), a geodetic point whose position on the earth’s surface is determined by triangulation. The exact location of a triangulation station is fixed by placing a special structure, called a geodetic center, in the ground and is given by the coordinates in a chosen system of geodetic coordinates. The horizontal coordinates of a triangulation station are calculated from the triangulation, and its height above sea level is determined by trigonometric or geometric leveling. Triangulation stations, like traverse stations, make up a geodetic control network, which is used in topographic surveying and in various geodetic measurements.
