Designing a geodetic network through the search method based on the use of an undistorted model

Abstract

General idea of the search method is provided. An information flowchart explaining themethod is presented. Formulas for evaluating the project of a geodetic network using the search method based on the undistorted model are given. The sequence of the mentioned design algorithm based on the undistorted model is developed. A computer program for evaluating the project in Visual Basic was compiled. The design and evaluation of the project of two networks, a triangulation geodetic and the one built according to the free stationing scheme was made. Both networks were constructed using the search method of nonlinear programming based on the undistorted model. The results of the evaluation of the triangulation network project coincided with those performed by the classical parametric method, which confirmed the correctness of the proposed algorithm for designing a geodetic network using the search method. The full weight matrix of coordinates of the defined points was obtained, and the average square error of the position of the weakest point in the network calculated.
