Computing vertical-angle. In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to it from known points.

Specifically in surveying, triangulation involves only angle measurements, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration.

Traverse adjustment by the method of Least Squares allows precision estimation of the adjusted coordinates of traverse points as well as derived bearings and distances. Least Squares is an adjustment technique founded on well-accepted principles of measurements and their errors and is regarded as superior to all other methods of adjustment.

Trilateration is a method of control extension, control breakdown, and control densification that employs electronic distance-measuring instruments (EDMIs) to measure the lengths of triangles sides rather than horizontal angles, as in triangulation.

The triangle angles are then calculated based upon measured distances by the familiar law of. Principles of Block Adjustment of Aerial Triangulations by GORAN GALVENIUS Technical University, Stockholm, Sweden 1. Introduction.
