In accordance with the State Target Program for Airport Development for the period up to 2023, in order to increase the efficiency of state property management and meet the needs of the state in ensuring the stable development of the aviation industry, a number of theoretical studies and practical stages of creating a subsystem for managing engineering networks. According to the tasks and measures of this program, the development of a subsystem for the management of engineering networks at the airport is a relevant and promising area. Engineering networks to ensure the smooth operation of the airport complex may include units that perform the functions of operation of utility networks of different types of planning of current and future development. This is a complex territorial and technological complex, for the optimal functioning of which requires no less complex management information system, which in turn requires laying already at the stages of developing capabilities to perform two communicative functions: the first one - to unite all airport subsystems, the second one - to coordinate relations with other airport systems, management and its divisions. The paper analyzes and summarizes publications on methods of geospatial data generation, introduction of geoinformation technologies for administrative and economic management of airports, as well as publications on information systems of branched areas of public utilities as a system of economic work of the airport, in particular, water supply and sewerage, energy and heat supply, outdoor lighting of the airport and runways, sanitation, etc. Analysis of recent research and publications showed that the prospects for the introduction of geographic information technology for administrative and economic asset management of Ukrainian airports need further research, as these issues are very important and relevant, given the rapid growth of digital society, environment and infrastructure. The main purpose of the study is to develop models for the formation of geospatial data subsystem management utilities airport, their processing and visualization, application of geographic mapping systems and the formation of conceptual approaches to the creation, operation and application of geographic information systems and technologies to solve administrative problems. The structure of the subsystem was determined and the basic sets of geospatial data of the airport were established, which include a single cartographic basis for the location of profile sets of engineering infrastructure. The formation of geospatial data sets is in accordance with the international standards ISO 19100 «Geographic Information / Geomatics», which provides the use of data in various software, access to open data, services and programs that can be easily integrated without the need for refinement and based on common standards and concepts of modern information technologies. Using the classifier of topographic information of scales 1:500 - 1:5 000, the list of names of objects of classification of subsystem of management of engineering communications of GIS, classification groups and their code designations from a class of objects 51300000 «Communications» is formed. Digital representation of objects is performed in accordance with the set of standards «Topographic Database», which allows to unify the structure and composition of digital terrain models in topographic databases for compatibility of geospatial data of different manufacturers. On the basis of the conducted research, the theoretical bases of cartographic maintenance of functioning of GIS for successful management of operational services of various types of engineering networks of a complex of the airport are developed. This is done taking into account the specifics of the object of study (airport) and the capabilities of modern GIS, the main function of which is to conduct cartographic modeling based on geoinformation analysis of geospatial and attributive data of engineering communications of an airport.
