Minimum-weight triangulation — triangulation of minimum total edge length; Kinetic triangulation — a triangulation that moves over time; Triangulated irregular network; Quasi-triangulation — subdivision into simplices, where vertices are not points but arbitrary sloped line segments; Volume mesh — consists of three-dimensional shapes
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 antiquity.
Illustration from an edition of 1726 Gemma Frisius's 1533 proposal to use triangulation for mapmaking Nineteenth-century triangulation network for the triangulation of Rhineland-Hesse. Triangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and gun direction of weapons.
Key performance indicators define a set of values to measure against. These raw sets of values, which can be fed to systems that aggregate the data, are called indicators. There are two categories of measurements for KPIs. Quantitative facts presented with a specific objective numeric value measured against a standard. Usually they are not ...
In the social sciences, triangulation refers to the application and combination of several research methods in the study of the same phenomenon. [1] By combining multiple observers, theories, methods, and empirical materials, researchers hope to overcome the weakness or intrinsic biases and the problems that come from single method, single-observer, and single-theory studies.
[1] [2] The expenditure for managing the data is great. The second and simpler concept is the marching method. [3] [4] [5] The triangulation starts with a triangulated hexagon at a starting point. This hexagon is then surrounded by new triangles, following given rules, until the surface of consideration is triangulated.
The transponders reply, and the replies are received again by the diver station (A). Signal run time measurements now yield the distances A-B, A-C and A-D, which are used to compute the diver position by triangulation or position search algorithms. The resulting positions are relative to the location of the baseline transducers.
[12] [13] Al-Bīrūnī, early in the 11th century AD, also used eclipse data, but developed an alternative method involving an early form of triangulation. For two locations differing in both longitude and latitude, if the latitudes and the distance between them are known, as well as the size of the earth, it is possible to calculate the ...
