摘要
随着GIS技术的发展和电力信息系统管理需求的不断提高,针对现有二维GIS在电力信息系统应用中的局限,探讨了三维GIS在电力信息系统中的应用,重点讨论了数据组织和空间索引、多源数据的集成与管理、海量三维数据处理技术、组件技术和GIS与MIS的集成开发等关键技术,最后通过对基于卫星三维影像的输电线路综合信息管理系统的应用实例进行分析,得出将电力信息系统与三维GIS结合起来,同时综合管理电力信息系统中涉及到的各种地理数据和属性数据,可实现电力信息系统的可视化与自动化。
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.
