GIS空间数据与属性数据的文件组织结构研究
Research on File Organization Structure of GIS Spatial Data and Attribute Data
摘要
Abstract
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.关键词
