The article considers various methods for assessing the quality of the urban environment, their content, identifies strengths and weaknesses. In addition, the main users of these methods, who is the target audience, who the data is intended for and the possibility of making management decisions based on this data were identified. The article also presents a methodology developed by the authors that allows assessing the quality of urban areas by five main parameters using digital methods based on open city data. This will allow obtaining an objective picture of the state of the urban space and making adequate management decisions. This work is based on an integrated approach to assessing urbanized space, developing universal assessment models that allow correlating different-quality characteristics of city subsystems into a single assessment system, which will allow obtaining a quantitative assessment of the state of spatial indicators of the city. Digital methods of managing the life cycle of urban development systems imply entering a new stage of forecasting, programming and modeling the development of urbanized systems, eliminating serious consequences of urban development errors with large budget losses when implementing poor-quality development scenarios. The priority task of reforming the public authority system is to create a qualitatively new level of public administration efficiency, including in matters of spatial development of territories. The development of a methodological basis for modeling spatial development processes lays the foundation for creating new technological tools, developing digital platforms for spatial modeling of territorial systems development based on a big data system. As a result of the study, the main criteria and indicators of environmental quality were developed. The criteria matrix includes such evaluation blocks as transport and mobility; functionality of space; safety of space; accessibility; improvement of the environment. The evaluation criteria were tested in the Shaksha residential area and refined during a field survey of the city territory.
