Abstract: The knowledge of the location, shape and other characteristics of spatial objects in the coastal areas has a significant impact on the functioning of ports, shipyards, and other water-infrastructure facilities, both offshore and inland. Therefore, measurements are taken of the underwater part of the waterside zone, which means the bottom of water and other underwater objects (e.g. breakwaters, docks, etc.), and objects above the water, such as the above-water part of the waterside, breakwaters, hydraulic constructions, and other objects of the waterside infrastructure. In this paper, a project of a mobile inventory system for hydrotechnical objects using data from multiple sensors operating simultaneously will be presented. The aim of the project is to elaborate a mobile underwater scanning system which could be applied in various works requiring precise, detailed and coherent, underwater and above-water measurement, especially in areas associated with surveying, inspection and monitoring of objects in coastal areas. To elaborate the concept of the system, analysis concerning existing methods of precise underwater and above-water measurement, as well as the measuring equipment available, was carried out. The results of the research were used to develop the concept of a mobile system equipped with underwater laser scanning and acoustic positioning. The technology demonstration was developed using a specially-built laboratory environment that simulates hydrotechnical infrastructure with access to GPS data. The final stage of the project will consist of testing the system in open waters.
