3D Modelling in solution of cadastral and geodetic tasks

The main purpose of this study is demonstrating possibilities of using 3D modelling in solving scientific and practical problems et the field of geodesy and cadastre. Increasing number of publications on this topic among Russian and foreign authors are shown. The article considers examples of creating three-dimensional models for the purposes of cadastre and geodesy. A 3D model of cadastral registration of a complex object (gas station) in the specialized software ArchiCad together with Google Earth is presented. The composition of each stage and data set of each “step” of cadastral works in relation to such objects in Russian Federation are proposed. The article considers shortcomings of legal regulation in relation to 3D cadastre at the present stage. In addition, three-dimensional models of the Dukan reservoir (Iraq), showing water levels at different times, were modelled. They based on digital data obtained from the digitized contour map. And it were used such software products like GlobalMapper, ArcMap and ArcScene. After analyzing the regulatory sources, conclusions about the lack of legal regulation in relation to the 3D cadastre in the Russian Federation were made
