The data model and structure of power GIS

Abstract

This paper analyzed the application characteristics of the GIS in the power industry, and treated the data model and structure of the power GIS. It proposed a conceptual data model “four-dimension, four-division” based on the knowledge base, and proposed a cube structure based on the overall object-oriented power GIS model. The cube structure separate managed the semantic features, geometry, topology, real-time monitoring and other information of the electrical facilities in the form of components, and formed a highly efficient power GIS spatial data model.
