What is triangulation used for in surveying?

Triangulation in surveying is a fundamental method used to determine the location of a point by forming triangles from known points. This technique involves measuring the lengths of the sides of triangles formed by several survey points, where at least one point's position is known with precision. By applying principles of geometry, surveyors can calculate the positions of other points relative to these known locations.

The process hinges on accurately measuring the angles between various points and using those angles in conjunction with the known distance to ascertain the unknown distances and locations of additional points. This method is crucial in mapping and establishing property boundaries, as it combines geometric principles with practical surveying techniques.

While other options may relate to aspects of geodesy or data collection, they do not pertain directly to the specific function of triangulation in surveying contexts.
