摘要
围绕国家地理信息公共服务平台在线地理信息服务的需求,在分析国内外相关成果的基础上,提出了面向实体的数据建模思路,设计了地理实体数据模型,能够方便地实现地理信息与社会、经济、自然资源等专题信息的挂接,并有效解决多比例尺实体目标的一致性维护问题。
Information Society brings new requirements for on-line spatial data services. One of them is the entity-based spatial data framework that can integrate and support various social and economic information. Based on the analysis of state of arts of the field, the paper proposes a data model that can meet the requirement and can tie used for on-line information services via National Geo-spatial Information Service Platform.
