3D visualization is a key element of research and analysis and as the source used by experts in various fields e.g.: experts from water and sewage systems. The aim of this study was to visualize in three-dimensional space model of water supply network with relief. The path of technological development of GESUT data (Geodezyjna Ewidencja Sieci Uzbrojenia Terenu – geodetic records of public utilities) for water supply and measurement data from airborne laser scanning was proposed. Topological relationship tests were conducted. It was also checked, whether the current form of digital database of GESUT gives the ability to transform it into a three-dimensional. Authors analyzed the source data for completeness and consistency in accordance with regulation on county and national databases of GESUT. The article also refers to the actions that currently takes the Head Office of Geodesy and Cartography: K-GESUT and CAPAP. In both cases, the spatial data will have a coordinates in three-dimensional space. The use of spatial 3D database technology allows to detect and eliminate errors caused by: data conversion from analog, measurement errors, and collision detection of objects designed with existing objects. Visualization of the spatial data sets influences the development of innovative applications of a three-dimensional spatial information. The advanced way of presenting spatial data is used in all kinds of analyzes, maps, simulation and modeling of phenomena. There is possibility to use 3D data in the inventory process and replacing site visits and the use of data in the spatial planning.
