So the spatial data are integrated, a unified spatial index database is built in the space within the framework of the index generating Hilbert space-filling curve scan matrix, to get one-dimensional mapping between Hilbert space arrangement of coding and spatial index information. A reasonable and efficient spatial index algorithm is designed for the overall planning and design. Unified operating methods are proposed for data integration, with a system architecture to improve the level of work for Geological Survey of information technology and complete data sharing and information service system. Experiments show that the system can directly access a relational database table for operation and maintenance, to avoid as much as possible the calls of the ArcGIS platform package ArcObjects correlation functions. In the realization of spatial indexing at the same time, the efficiency of spatial index is greatly enhanced. It provides a key spatial index system and a good support for data sharing for the geological survey information platform., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,

articleAbstract=在分布式空间数据库网络环境下，根据标准《地理信息元数据》，建立属于具体地质调查信息平台的空间数据库级和空间索引图层级两级元数据结构，并依此集成空间数据，构建统一的空间索引数据库；在空间索引范围内通过生成Hilbert空间填充曲线扫描矩阵，得到Hilbert空间排列编码与空间索引信息的一维映射关系，设计出合理、高效的空间索引算法。通过整体规划和设计，构建了统一的运行方式﹑数据集成方法和系统体系结构。试验表明，系统通过直接对关系型数据库级表之间的操作和维护，避免了调用系统依托的ArcGIS开发平台下ArcObjects封装的相关函数，在实现空间索引功能的同时，提高了空间索引效率，为地质调查信息平台建设提供了关键的空间索引体系和良好的数据共享支持。,
