In the view of the sections of the state information system for ensuring urban planning activities, the place is shown and the role in regulating the development of territories is revealed. The composition of spatial data contained in various types and sections of urban planning documentation is analyzed. A review of world practice has shown that many of the analyzed spatial data are included in national spatial data infrastructures, which indicates their high level of signifi cance. Consideration of the issues of updating graphic documents by maintaining duty plans of urban planning information using GIS technologies revealed the need to consolidate secondary (updated) documents at the legislative level. An analysis of the requirements for spatial data in the fi eld of urban planning and the real estate cadastre showed the need for their refi nement in terms of clarifying the requirements for the accuracy of describing the objects of urban planning activities and unifying the coordinate systems used. Proposals are given for the establishment of uniform requirements for methods for determining the coordinates of spatial objects and the rules for determining the permissible discrepancy, as well as requirements for the accuracy of determining the coordinates of the characteristic points of the boundaries of objects of urban planning activities.

The concept of basic sets of spatial data (BNPD) is investigated and an analysis of its implementa-tion in Russian legislation is carried out in order to assess the effectiveness of regulation of the circula-tion of spatial data in Russia. Based on foreign and Russian experience, the requirements for BNPD are determined. It is noted that the BNPD in Russia is primarily the unified electronic cartographic framework (EECO) and information to be presented using coordinates. The assessment of the EECO's compliance with the basic requirements for the BNPD showed that the EECO meets the advanced in-ternational approaches of spatial data infrastructure. To improve the efficiency of spatial data circula-tion in Russia, based on the analysis carried out, recommendations were made for the implementation of BNPD in the national spatial data system, including on improving the regulation of spatial data cir-culation in certain areas of legal regulation in the Russian Federation. The need for further research is substantiated in order to develop a technology for updating the EECO in a mode close to real time us-ing information from the unified state register of real estate, state information systems for ensuring urban planning activities and other state land information systems.

The purpose of the study is to reveal the features of the development of information support for urban planning in the context of digital transformation. The article summarizes new material on the topic under study: the latest amendments to the Urban Planning Code of the Russian Federation and relevant by-laws, prospects for the implementation of the national program "Digital Economy of the Russian Federation". The study provides a historical analysis of the development of information sup-port for urban planning. Particular attention is paid to the creation in the subject of the Russian Federa-tion of state information systems for ensuring urban planning with the functions of automated infor-mation and analytical support for the exercise of powers in the field of urban development (GISFUD) and the role of GIS technologies in its implementation. As a result of the study, there was proposed a scheme of information interaction between GISFUD and other information systems, including the Federal State Information System of Territorial Planning, the Federal State Information System for maintaining the Unified State Register of Real Estate, the Federal Information Address System, and the Unified State Register of expert conclusions for design documentation of capital construction facilities and the State Information System for maintaining a Unified Electronic Cartographic Basis for the ex-change of spatial data in order to provide automated support for the exercise of powers in the field of urban planning. The article defines the main trend of the digital transformation of urban planning ac-tivities, characterized by the transition to the provision of integrated services in the construction indus-try and the introduction of super services, as well as by the distribution of information models of capi-tal construction facilities and 3D printing in construction. It gives recommendations for digital trans-formation parameters in urban planning.

The article is devoted to an analytical review of the practice of taxation of land plots owned by business owners in non-residential premises as part of apartment buildings (in the context of this, the problematic issues of the formation of such land plots are considered). A contradiction was revealed in the part of land taxation in cases where economic activity is organized in the premises of detached non-residential buildings and in the specified non-residential premises. Proposals are given to eliminate the revealed contradiction, which creates the preconditions for dumping and discrimination against competition in product markets. Recommendations have been developed for eliminating imbalances in taxation in terms of withholding land tax and ensuring equal competitive conditions for participants in commodity markets. The prospect of further research is revealed.
