Study and Implement of Topology Analysis Based on Hyper-Nodes in GIS.

In order to take full advantage of the topology analysis mechanism provided by the Geographical information system (GIS) platform software, the graphical topology method is advised to express the topology in pipe network GIS. This paper puts forward the concept of hyper-node, which has two graphic objects which each belongs to different graphics worlds. It can help implement the topology analysis across different graphics worlds. Finally, the power supply range analysis of electrical equipment (such as transformers in substation) in electric power GIS is implemented, which will validate the feasibility of the topology analysis method based on hyper-nodes. ?
