Mei Hai · 2003
This paper describes the defaults of the traditional GIS system's three layers spatial data organization model when it is used to develop the GIS system for power network. We take advantage of the object-oriented idea to propose a new data organization model. Moreover we give a method to realize the model and how to set up the spatial index in relational database. This new data organization model can be well applied to the power network system, and has good application value to water supply network system, road network system and so on.\;
