Least squares adjustment is a model for the solution of an overdetermined system of equations based on the principle of least squares of observation residuals. It is used extensively in the disciplines of surveying , geodesy , and photogrammetry —the field of geomatics , collectively. There are three forms of least squares adjustment: parametric , conditional , and combined.

The Surveying Handbook pp Cite as. The general subject of errors in measurement was discussed in Chapter 3, and the two classes of errors, systematic and random or accidental , were defined. It was noted that systematic errors follow physical laws, and that if the conditions producing them are measured, corrections to eliminate these can be computed and applied; however, random errors will still exist in all observed values.

Adjustment Computations: Statistics and Least Squares in Surveying and GIS

The method of least squares is a standard approach in regression analysis to approximate the solution of overdetermined systems sets of equations in which there are more equations than unknowns by minimizing the sum of the squares of the residuals made in the results of every single equation. This work presents basic methods in least squares adjustment computation. Least squares adjustments have their roots in the normal distribution, which is pictured in Figure 1. The equation for the normal distribution curve is Equation 1 where:.

August Presently there are several masterpieces on this subject, such as the famous works by Bjerhammar , Mikhail and Koch , just to mention a few of them. However, the author still feels the need for a middle-level textbook in this eld. A textbook that balances between practical applications and pure mathematical treatments; A textbook that integrates classical adjustment methods with modern developments in geodesy, surveying and photogrammetry.

 Он прячется в укрытии. Стратмор пожал плечами. - Танкадо выехал из Японии. Он собирался следить за ходом аукциона по телефону.

И, как бы желая обратить все в игру, сделал еще один шаг. Но он не был готов к тому, что произошло в следующее мгновение. Сохраняя ледяное спокойствие, Сьюзан ткнула указательным пальцем в твердокаменную грудь Хейла и заставила его остановиться. Хейл в шоке отпрянул, поняв, что она не шутит: Сьюзан Флетчер никогда еще до него не дотрагивалась, даже руки не коснулась. Правда, это было не то прикосновение, какое он рисовал в воображении, представляя себе их первый физический контакт, но все же… Хейл долго с изумлением смотрел на нее, затем медленно повернулся и направился к своему терминалу.

В дальнем углу, прямо под табло, которое когда-то показывало счет проходивших здесь матчей, он увидел слегка покосившуюся телефонную будку. Дай Бог, чтобы телефон работал, мысленно взмолился Беккер.
