INTEGRATION OF GRAPHIC AND SEMANTIC INFORMATION IN GEOGRAPHIC INFORMATION SYSTEMS OF DISTRIBUTION ELECTRIC NETWORKS

One of the important and promising areas for increasing the efficiency of managing the operation of distribution electric networks is the use of geographic information systems (GIS). In geographic information systems, graphical and associated with it attributive (semantic) information is used. Maps, plans, diagrams with distribution electric networks printed on them are used as graphic information in geographic information systems. Databases of electrical equipment are used as semantic information for the description of distribution electric networks. Thanks to the joint processing of graphic and semantic information in geographic information systems, the efficiency of all stages of working with spatial data is increased. Starting from the search, selection and analysis of spatial data to the development of a specific solution for managing the operation of distribution electric networks. The article analyzes the feasibility of using a formal number as a unique identifier. Three approaches to the organization of the joint work of graphic and semantic information in geographic information systems have been considered. Structural schemes, advantages and disadvantages of ways of integrating graphic and semantic information have been given. The features of integration of graphic and semantic information in geographic information systems of distribution electric networks have been also considered. The prospects of using an object-oriented approach to organizing the joint work of graphic and semantic information in geographic information systems have been noted.
