The work raises the question of the urban development using a digital model based on the results of airborne laser scanning for the municipality administration needs. The processes of air laser scanning and subsequent cameral processing of the results are described. Specialized software for analyzing the information received and authors’ methods for classifying the objects are considered. The available achievements analysis in the field of city models compilation and the analysis of natural and man-made objects obtained from aerial surveys of urban areas is carried out. The conclusions are drawn about the prospects for the application and development of this technology for the purpose of accounting and monitoring the urban areas in terms of its impact on the urban economy, the quality of the population life and forecasting emergencies.

The paper is devoted to topical issues of monitoring infrastructure facilities. The aim of the study is to compare the already established traditional method of ground-based laser scanning and its aerial analogue based on the use of compact drones in collecting data on road structures. The question was raised about the possible ways to modernize the existing monitoring procedure for the timely detection and prevention of dangerous emergencies at engineering structures. The most effective technologies for obtaining comprehensive information on the technical condition of such structures are analyzed. It was determined that the most rational method from the point of view of information content, mobility and examination time is the method of using airborne laser scanners in conjunction with unmanned small-sized aircraft. The procedure of the entire cycle of obtaining information, including its subsequent processing, is described. The analysis of stationary and other applied methods of monitoring infrastructure facilities is made, their advantages and disadvantages are described. A question was raised about the prospect of creating software that uses artificial neural networks as a means of automating the processes of subsequent processing of primary scan data and analysis of the obtained object model. Conclusions are made about the appropriateness and prospects of using similar tools and methods for the needs of monitoring engineering infrastructure facilities, as well as the need for further development of software that will automatically analyze the accumulated data on the same infrastructure object.

The purpose of this work is to develop a methodology for monitoring real estate objects, as a single information block, by including this procedure for capital construction objects in the process of land use control to update the information contained in state systems. The object of the research is the systems of state monitoring of land use based on the automated information system of state monitoring of land and registration of immovable objects based on the federal state information system of the Unified State Register of Real Estate. The subject of the work is creation a concept for a system of monitoring immovable objects, as a single resource, by introducing a monitoring unit for capital construction ones. As a result of the research, the stages of the method implementation are described, the key users of the final monitoring system for real estate objects are presented and options for its practical application are indicated.

In the Russian Federation, the issue of improving the cadastral system is currently more relevant than ever. This is determined by the complication of the procedure for designing and building the cadastral real estate objects. Modern architecture is becoming more complex and diverse year-by-year. The configuration of the construction facilities is becoming more increasingly complex, and these days, they can be built not only on the ground surface but also above or under the ground. In practice, such design solutions lead to uncertainty and ambiguity of their routine cadastral registration, and these objects are registered according to their two-dimensional projection on the ground. Currently, almost all design agencies use 3D simulation in solving issues related to the design, construction, and sale of both industrial or agricultural facilities and residential or office buildings and apartments. Leading Krasnodar enterprises engaged in the design of various real estate objects use three-dimensional models in providing customers with the complete scope of work. The paper authors reveal the basic concepts of a three-dimensional cadastre in a modern system of engineering, design, construction, and architecture. The prerequisites for switching to the 3D cadastre have been considered, the cadastral registration aspects specified, and the issues concerning three-dimensional representation and processing 3D real estate data discussed. The main 3D data representation models are listed.
