摘要
针对跨平台三维可视化管理系统开发过程中二维属性数据、空间数据在管理和分析时存在的问题,提出在三维管理系统中嵌入Spatialite空间数据库。一方面利用其对属性数据和空间数据的综合管理能力,以及可跨平台的特性,实现数据库同步过程的一致性和完整性;另一方面利用Spatialite空间数据库的空间分析和查询功能,并结合三维实时渲染技术,使用三维特效输出查询结果,实现数据分析、查询结果的三维可视化。
According to the existing problems of two-dimensional attribute data,spatial data management and spatial analysis in 3D data management system development process,a method that Spatialite spatial database is inset to the three-dimensional management system was raised with the centralized management of spatial data and attribute data from the data layer. Using the functions of spatialite spatial analysis and query,and combining with the 3D real-time rendering technology can not only simplify the 3D spatial topological operations management system,but also improve the query efficiency.
