Triangulation station - GIS Wiki | The GIS Encyclopedia

UseUnited KingdomAustraliaPhoto GallerySee AlsoExternal LinksThe station is usually set up by a government with known coordinate and elevation published. Many stations are located on the peaks of hills for the ease of being spotted from many directions. A graved metal plate is on the top of a pillar for securing a theodolite or reflector. Trigonometrical stations are grouped together to form a network of triangulation. Positions of all land boundaries, roads, railways, bridges and many other infrastructurescan be accurately located by the network. Trigonometrical stations are essential to the construction of modern infrastructure. Apart from the known stations set up by government, some temporary trigonometrical stations are set up near construction sites for monitoring the precision and progress of construction. Some trigonometrical stations are equipped with Global Positioning Systemswhich greatly improve their accuracy.
