The research aims to complete the study of the theory and operation of networks geodesic associated marine beach, whether horizontal or vertical, with display rods and devices used in completion of topographic survey of networks in both land and marine parts. In theoretical part it was addressed to specific shapes networks geodesic which distinguish maritime works beach that takes the form of the morphological characteristics of the natural land of each building proposed network, and the numerical characteristics of each building proposed networks. In the practical part the results of measurements and amendments was presented to some forms of executed geodesic beach networks for several forms of works: (topographic raise achievements within the existing and investor basin in order to establish a slider, completion of the cadastral beach works in order to determine distortions in the existing pier, clean the shipyard of silt and sediment. Software has been reviewed to assist in completing marine works, utmost to obtain the final marine charts. The research concluded that specific proposals on vertical geodetic networks studies, and identify the various parts of software related to marine works and ways to take advantage of them.
