Using three-dimensional(3D) visualization technology to realize the management of transmission lines is a current developing direction on electric power information. However, the Earth is an irregular ellipsoid, which makes it hard to work out the coordinates in world space on the tower hanging point. Furthermore, it cannot truly describe the connecting condition between lines and tower hanging point. For these reasons, on the basis of analysis and research, we provide a hanging point calculating method that use the tower space of Google Earth as a starting point. The method is applied to the developed transmission line management system. With the characteristic of simple calculation, high precision, as well as having a real connection line and hanging point, etc. This method can meet the requirements of existing applications.
