Technology of three-dimensional laser scanning of real estate objects (3D modeling) in cadastral activities

Abstract

Laser scanning in cadastral activities is a tool for obtaining information about real estate objects in a 3D format. The purpose of the research is to obtain information that is necessary for state cadastral registration and state registration of rights, land supervision and local government oversight. Deductive, inductive, analytical, comparative-legal and other scientific methods were used for the most complete coverage of the problem. The article considers the procedure of laser scanning, shooting modes when using laser scanning and the process of a real estate object 3D model creation. The methods of scanning were studied, namely: terrestrial, airborne and mobile. The greatest attention is paid to the advantages and features of using laser scanning technologies for real property. The results of the study showed that the laser scanner can be used not only in geodesy for engineering surveys, 3D modeling of quarries, when obtaining data on the volume of rock, during mining, assessing the situation in an emergency, but it can also be used in cadastral and complex cadastral works. The main attribute of laser scanning is a three-dimensional representation of data about the object, which can be immediately used, but the high accuracy and low labor costs are no less important. Therefore, three-dimensional laser scanning technologies can be used both in the creation of models of cities, and the unified cartographic basis of the Unified State Register of Real Estate, as well as in valuation activities during the taxation of buildings and structures.
