kart. Etat : Gut. 483 S. ; 21 cm, Gutes Ex. - Aufgabe der Ausgleichungsrechnung ist es, mathematische Modelle an empirische Daten (Messungen, Beobachtungen) optimal anzupassen. Gegeben wird ein systematischer Überblick über Grundsätze, je nachdem ob die Variablen im allgemeinen linearen Modell stochastisch angesetzt werden oder nicht. Im Falle nichstochastischer linearer Modelle werden die Methoden der kleinsten Quadrate L2-Norm-Optimierung) und der minimalen Norm unter Verwendung von generalisierten inversen Matrizen behandelt. Die stochastischen linearen Modelle, ausgehend vom Speziellen Gauß-Markov-Modell mit und ohne Restriktionen über das Allgemeine Gauß-Markov-Modell mit Datumdefekt (Kollinearität) und singulärer Dispersionsmatrix bis hin zum Gemischten Gauß-Markov-Modell mit fixen und Zufallsparametern werden hierarchisch gegliedert. Schätzverfahren werden getrennt für Ausgleichungsund Prädiktionsmodelle, für das Moment erster Ordnung in linearer Form, für das Moment zweiter Ordnung in quadratischer Form der Meß-daten, vorgestellt. Die in Betracht kommenden Zielfunktionen sind von der Art Erwartungstreue, minimale Verzerrtheit, Translationsinvarianz, minimale Varianz und ihre Kombination. Die zentralen Äquivalenzsätze beinhalten als Höhepunkt Aussagen darüber, daß die stochastischen Zielfunktionen durch algebraische Approximation in gewissen linearen Gleichungssystemen erfüllt werden. Z.B. wird die beste lineare erwartungstreue Schätzung ("BLUE") im klassischen Gauß-Markov-Modell als Lösung nach der Methode der kleinsten Quadrate ("LESS") im zugehörigen linearen Gleichungssystem gefunden. Reichhaltige numerische Beispiele geben Einblick in die theoretischen Resultate. (Verlagstext) ISBN 9783411163816 Sprache: Deutsch Gewicht in Gramm: 550.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - During the period April 25th to May 10th, 1984 the 3rd Course of the International School of Advanced Geodesy entitled 'Optimization and Design of Geodetic Networks' took place in Erice. The main subject of the course is clear from the title and consisted mainly of that particular branch of network analysis, which results from applying general concepts of mathematical optimization to the design of geodetic networks. As al ways when dealing with optimization problems, there is an a-priori choice of the risk (or gain) function which should be minimized (or maximized) according to the specific interest of the 'designer', which might be either of a scientific or of an economic nature or even of both. These aspects have been reviewed in an intro ductory lecture in which the particular needs arising in a geodetic context and their analytical representations are examined. Subsequently the main body of the optimization problem, which has been conven tionally divided into zero, first, second and third order design problems, is presented. The zero order design deals with the estimability problem, in other words with the definition of which parameters are estimable from a given set of observa tions. The problem results from the fact that coordinates of points are not univocally determined from the observations of relative quantities such as angles and distances, whence a problem of the optimal choice of a reference system, the so-called 'datum problem' arises.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - In the context of Geographical Information Systems (GIS) the book offers a timely review of Map Projections. The first chapters are of foundational type. We introduce the mapping from a left Riemann manifold to a right one specified as conformal, equiaerial and equidistant, perspective and geodetic. In particular, the mapping from a Riemann manifold to a Euclidean manifold ('plane') and the design of various coordinate systems are reviewed . A speciality is the treatment of surfaces of Gaussian curvature zero. The largest part is devoted to the mapping the sphere and the ellipsoid-of-revolution to tangential plane, cylinder and cone (pseudo-cone) using the polar aspect, transverse as well as oblique aspect. Various Geodetic Mappings as well as the Datum Problem are reviewed. In the first extension we introduce optimal map projections by variational calculus for the sphere, respectively the ellipsoid generating harmonic maps. The second extension reviews alternative maps for structures , namely torus (pneu), hyperboloid (cooling tower), paraboloid (parabolic mirror), onion shape (church tower) as well as clothoid (Hight Speed Railways) used in Project Surveying. Third, we present the Datum Transformation described by the Conformal Group C10 (3) in a threedimensional Euclidean space , a ten parameter conformal transformation. It leaves infinitesimal angles and distance ratios equivariant. Numerical examples from classical and new map projections as well as twelve appendices document the Wonderful World of Map Projections.
