Report on the round table in the State Duma dedicated to the cadastral reform

Currently, the introduction of a 3D cadastre of real estate objects in Russia is quite relevant, since using a two-dimensional cadastre it is impossible to keep records of various multi-level objects such as bridges, tunnels, road junctions, etc. In this scientific work, the most time-consuming stage of a three–dimensional cadastre is considered – 3D modeling of various real estate objects and obtaining of spatial information about them. The article analyzes two main methods of spatial data acquisition - aerial photography and three–dimensional laser scanning. The advantages and disadvantages of these methods are considered in this paper. In conclusion, the authors advise to use the mentioned methods of obtaining data to create 3D models in a three-dimensional real estate cadastre.
