Abstract: With numerous transmission lines, how can their ledger information like the path directions and voltage levels be known rapidly? How can the dangerous points within the transmission line channel, including bird nests, tree barriers and artificial buildings, be recognized quickly? How can the information of the transmission lines be shared with the line design department efficiently and securely? How can the information of the transmission line channel status be updated rapidly? In response to these issues, making use of integration methods of GIS technology, information technology, UAV and ground intelligent identification, the GIS Based Haining Transmission Line Channel Management System is constructed. This system can greatly improve the efficiency of transmission line management and realize the automatic identification and early warning of dangerous objects in the channel to ensure the safety of the channel.
