面向生产的一体化空间数据模型

Production-oriented Integration Geodata Model

在分析了现有典型空间数据模型的基础上,提出了一种面向生产的一体化空间数据模型。该模型将实体的几何和拓扑信息紧密联系在一起,具有较强的空间表现力,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,并能支持GIS数据和制图数据的一体化生产。实践表明,采用该数据模型,有效地提高了空间数据生产的质量和效率。

On the base of the analysis of current spatial data model, this paper puts forward a new production - oriented integration geodata model. The geometry and topology information of an entity are connected in this model. The model has a strong ability for spatial representation. Meanwhile, it is able to maintain the consistency of spatial data in terms of geometry, attribute and topology in real time. Furthermore,it can support the integrative data production for GIS and mapping. A system with this model can improve the quality and efficiency of spatial data production effectively.
