Tríhyrningsmælingar

Tríhyrningsmælingar, often translated as triangulation, is a mathematical technique used to determine the position of a point by measuring angles to it from two other known points. This process relies on the principles of trigonometry, specifically the sine rule. By knowing the distance between the two known points (the baseline) and the angles formed at these points towards the unknown point, a triangle is created. The lengths of the other two sides of this triangle, which connect the known points to the unknown point, can then be calculated.

This method is fundamental in various fields. Surveying extensively uses triangulation to map land, determine property boundaries, and establish control points for larger projects. In astronomy, it has been historically employed to measure distances to nearby stars and celestial bodies. Navigation, both on land and at sea, has also benefited from triangulation, though it has largely been superseded by more advanced technologies like GPS. The core concept remains the same: using geometric relationships and known distances to pinpoint unknown locations. The accuracy of triangulation depends heavily on the precision of the angle measurements and the length of the baseline.
