Optimization methods in geodetic networks

Original language description

The optimization of geodetic network is often neglected but very important topic in the field of engineering surveying. The optimization is necessary especially for networks with high accuracy requirements like deformations monitoring networks. Mathematical optimization is often replaced by a design based on experience developed on the basis of known accuracy of elementary tasks. Optimization means minimizing measurement costs fulfilling the requirements for accuracy or reliability. We distinguish several types of optimization by parameters of geodetic network deals with. They are called zero, first, second and third order design. Most of the articles engage in first and second order design, which solve optimal point position and weight of observations respectively. These problems are solvable by well-known optimization algorithms like linear or quadratic programming. These algorithms generally operate but practical use is rare. Recently, many new optimization algorithms were created in connection with strong increases in computing power. Examples include genetic algorithms, simulated annealing or particle swarm algorithm. These methods can be applied to geodetic networks and can solve previously unsolvable problems. In this paper, will be discussed known methods of optimization and will be evaluated applicability of them in designing of real networks.
