| 摘 要： | 提出一种适合于多值矢量图的ＧＩＳ数据模型（包括图形数据模型和属性数据模型）。该模型既适合于关系数据库结构，也适合于面向对象数据库结构。根据该模型设计了一种基于关系数据库模型珠图形与属性一体化数据结构。该模型和结构既适用于二维图，也适用于数字地面模型（ＤＴＭ）。该数据结构已应用于ＧＩＳ软件（ＧＩＳＩＤ）中，效果很好。

| Abstract: | In this paper, a data model of GIS, including geometrical and semantical data, available for multi-valued vector maps is proposed. The model is suitable for not only relational database structure, but also object oriented database structure. The relational data sturcture with integrity of geometry and semantics is designed based on the model. The data model and structure are suitable for not only 2D maps, but also DTM. The data structure has been used in a GIS software named as GISID and proved very effective. |
