|
摘要
围绕地理空间数据的快速增长和广泛深入应用,系统分析了海量数据存储管理现状及面临的问题和不足;结合地理空间数据自身属性特点,归纳提出了地理空间数据存储管理需要满足的技术要求和发展趋势;提出了一种基于GeoSOT剖分网格技术的数据存储架构设计思路,并研究分析了其涉及的关键技术。谈架构可为海量地理空间数据的集中存储、统一管理、联动更新、共享交换和按需服务提供优化解决方案和有力技术支撑。
Around the rapid growth of geospatial data and extensive application, current situation and main problem of mass data storage management are analyzed systematacially in the paper. Combining the attribute characteristics of geospatial data, the technical requirements and developing trend of the storage management of geospatial data are pointed out. In view of this, a storage architecture design of geospatial data based on GeoSOT is proposed and the key related technologies are analyzed, which can provide optimal solutions and strong technical support for centralized storage, unified management, linkage updating, sharing and exchanging, and on-demand service.
