One of the most outstanding characteristics of GIS is its enormous space data.In addition,GIS data is a geographical information space with various types,endless extent and extraordinary complexity while the complete expression and management of the space are always the center of the GIS research.Based on the object of space data in GIS,this paper explores the establishment of the space data model and the method to save the space data.
