Abstract: With the development of GIS technology and the continuous improvement of electric power information systems management needs, for the limitations of existing two-dimensional GIS in electric power information system applications, the paper explores the application of three-dimensional GIS in electric power information system, focuses on data organization and space index, multi-source data integration and management, mass three-dimensional data processing technology, component technology, integration development of GIS and MIS, and other key technologies. Finally, by analyzing the application example of the transmission line integrated information management system of satellite-based three-dimensional images, combining the electric power information systems with three-dimensional GIS, and at the same time, integrating the geographic data and attribute data involved in electric power information system, the visualization and automation of electric power information systems can be realized.
