针对传统GIS数据管理方法都是将空间数据与属性数据分隔开来分别进行管理的缺点,提出一种用于将空间数据和属性数据进行统一管理的文件组织方法。文中分别给出空间数据和属性数据的数据结构,然后采用层次性结构化文件系统结合文件索引和数据字典技术来对空间数据和属性数据进行统一管理。该方法能够对各实体信息表示尽量结构化,从而加快大数据量应用的存取速度。

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.
