| 摘 要： | 本文在分析了目前常见空间数据模型的基础上,提出了一种面向拓扑的地理空间数据数据模型.该模型将实体的几何信息和拓扑信息紧密联系在一起,具有较强的空间表现力,能支持GIS数据和制图数据的一体化生产,并能够实现空间数据的几何、属性和拓扑关系一致性的实时维护.实践表明,该模型能有效地提高空间数据生产的质量和效率.

| Abstract: | Based on the analysis of spatial data model,this paper put forward a orient-topology geospatial data model.The geometry information and topology information of an entity were connected in this model.The advantages are a strong ability for spatial representation,to support the integrative data production for GIS and mapping and being able to maintain the geometry,attribute and topological consistency for spatial data in real time.This model could improve the quality and efficiency availably. |
