Aimed to the shortcoming that the spatial data and attribute data are managed separately by the data management method of traditional GIS,a kind of file organization method to manage the spatial data and attribute data integrately is put forward in this paper.The data structure of the spatial data and attribute data are given respectively,then the spatial data and attribute data are managed centralizedly by adopting the hierarchy structured file system which is combined with file index and data dictionary techniques,this method can express the various entity information to be structured,thus to accelerate the access speed of large amount of data applications.
