摘要
介绍一种可用于ＧＩＳ的文件结构，即图元文件。它能有效地组织ＧＩＳ的地理空间信息，方便地实现多层次的复杂的地理空间信息的识别、编辑、分析运算、管理与查询，有利于建立开放式的ＧＩＳ文件系统，实现信息资源的共享。
In this paper,a file structure is introdticed which is called metafile in Microsoft Win-dows and can be tised in GIS. This file structure can be used to organize the geographicalspacial information of GIS effectively,and also can be used to distinguish,edit,analyse,compute,manage and query of multiple complex geographical spacial information. It’s ad-vantageous to building the openning GIS file system and also realizing the resources shar-ing of information together.
