Abstract: The authors expatiate the significance of introducing professional analysis to electric transmission & distribution network based on geographic information system(GIS),and put forward a solution to establish an electric GIS based on ArcInfo,ArcSDE platform which can model the network and manage the database to develop a multi-user electric GIS,which has function of line-wasting analysis programmed by ArcSDE API and ArcObjects.The authors expatiate on the method of modeling and the key of programming of the solution emphatically.
