The three dimensional geodetic networks adjustement automation using Matlab

A three dimensional geodetic network is composed by a system of points located on earth's surface, on an engineering work territory, points which have a known position in an unitary reference coordinate system. Geodetic networks play a significant role in the attainable accuracy of surveying and mapping applications. This paper presents a three dimensional geodetic network in form of a closed loop traverse, which begins and ends at the same point station. In order to determine the traverse station points coordinates, the least squares method of indirect observations was used. The primary objective of this paper is writing a Matlab program with procedures and functions, which automatically calculates the unknown points coordinates, respectively their accuracy, thus streamlining the measurements processing.
