摘要: 利用面向对象技术,将嵌入式GIS系统抽象为元素模型、要素模型、地图表示/表现模型、地理数据计算/分析模型、空间数据压缩/索引模型和Web服务支持模型,讨论分析模型的设计、其间的组织关系、管理方式和实现机制,并对模型的应用和存在的问题进行简要阐述。

Abstract: Using the object-oriented technology, the paper generalized and abstracted the embedded-GIS into such models as element, feature, map representation & rendering, geo-data computation & analysis, spatial-data compression & index and web services supporting. It discussed the design, organized relation, and management method, implementation technique between these models. At the end of paper, it gave some brief statements on models application and existed problem.

Key words: object-oriented technology, data model, embedded-GIS, feature, element
