Triangulaatio
Triangulaatio, or triangulation, is a method for determining a position or the shape of an object by forming triangles from known reference points. The core idea is to use measurements—usually angles between lines of sight or distances—to locate an unknown point as the intersection of geometric constraints. In practice, triangulation often involves a baseline of two known points and angle measurements to the target point; the unknown location is found by solving a system of trigonometric equations. Distances-based methods are sometimes called trilateration, while triangulation relies on angle measurements.
In surveying and cartography triangulation has been used to build control networks and maps; in navigation
In research methodology, data triangulation denotes using multiple data sources or methods to cross-verify results; forms
Method and tools: Baseline measurement, angle measurement with theodolite or total station; GNSS coordinates; laser scanning;
Limitations: Accuracy depends on configuration geometry, baseline length, and angular precision; measurement errors, occlusions, and atmospheric
History: The technique has ancient roots in surveying and remains a fundamental approach in geospatial science
