A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, ... hills or tall buildings.
Measuring the height of a building with an inclinometer. Triangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and, in the military, the gun direction, the trajectory and distribution of fire power of weapons. The use of triangles to estimate distances dates to ...

Triangulation of Kodiak Island in Alaska in 1929. In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration. The point can then be fixed as ...
Prominent features on buildings such as the tip of a church spire or a chimney stack are also used as reference points for triangulation. In the United Kingdom, triangulation points are often set in large concrete markers that, as well as functioning as triangulation points, have a benchmark set into the side. With the increasing use of GPS and ...
The triangulation was connected to both Norway and Iceland using HIRAN, an enhanced version of SHORAN. Survey connections extending from primary triangulation points in Scotland to triangulation points in Norway and Iceland were facilitated by the US Air Force under the implementation of a project known as the North Atlantic Tie.

In a network of fourteen cities a total of 53 triangulation measurements were made. In his calculations Snellius made use of a solution for what is now called the Snellius–Pothenot problem. Snellius' Triangulation (1615) By necessity Snellius's high points were nearly all church spires. There were hardly any other tall buildings at that time ...
