The urban geographic information system includes a wide range of different types of complex data collected from various sources and provides a solution for city planning, architectural and construction design. The complex structure of the city determines the complex nature of information models and data flows in them. In order to increase the efficiency of existing processes in various areas and directions of urban space planning the state-of-art digital technologies are widely used. Obtaining experimental data in silico is less costly in terms of both material and time resources. Carrying out primary researches in planning of urban space is a task that requires a comprehensive analysis of various factors of the urban environment ensuring the accuracy of conducted computations. Therefore, the development of a support system for decision-making in modification of urban space is both burning and topical and has a widely recognized scientific and practical value.

The article describes geographic information system that forms a multi-level urban space modeling environment combining data from heterogeneous sources, so it make it possible to reduce time costs for designing and improvement of urban space. The implementation of such a system implies the use of modern digital technologies that capture the geographic information of objects and the development of algorithms for multi-criteria assessment of the generated alternatives for the location of urban objects and infrastructure facilities. The purpose of the work is to increase the efficiency of primary engineering and construction surveys based on geoinformation technologies, which are widely used to solve various problems, and with the development of digital technologies it becomes possible to expand their functionality. So, one of the topical areas is the use of three-dimensional visualization. Three-dimensional display of the distribution of objects and resources in space can greatly increase the efficiency of urban space planning, transport dispatching, and emergency prevention at utility facilities.

This paper considers a system designed to perform the tasks of urban space design using geoinformation technologies, including three-dimensional visualization tools, automation of spatial position calculations based on multi-criteria analysis and evaluation of generated design scenarios. The description of the basic principles of the functioning of the GIS is given, aimed at optimizing the conduct of primary engineering and construction surveys and providing a description of the infrastructure of underground utilities, which ensures the implementation of a set of engineering works when calculating the relative position of heterogeneous city objects, taking into account their relationships using a multidimensional representation of urban space; the process of comparative analysis of various options for the placement of objects in the urban space, formed on the basis of three-dimensional modeling, is demonstrated. An approach of the formation and multi-criteria assessment of options for placing urban objects on the basis of the carried out research is represented. Estimates of compared options are obtained based on the use of the analytic hierarchy process (AHP). The obtained results demonstrate the compliance of the functional characteristics of the system with the requirements for the accuracy of calculations of the spatial location of objects and multicriteria analysis of the urban environment.

One of the key features of the system is the accounting of underground utilities, which makes it possible to form a comprehensive assessment of the location of buildings and structures while ensuring accuracy that meets the requirements of engineering and construction surveys, due to modern photogrammetry methods, which resulted in a three-dimensional model of the city. Also, the multi-level nature of the model allows you to choose the location of objects, satisfying the conditions for the inclusion of new objects in the existing infrastructure in terms of the availability of utilities, as well as the context of the urban environment.
