多尺度地理空间数据的分布式存储与管理

Think About the Distributed Storage and Management of Multi-scale Geographical Spatial Data

多尺度地理空间数据分布式存储与管理技术为建立分布式网络地理信息系统、实现多尺度、多数据类型数字地理信息产品一体化分发和应用提供技术支撑。本文重点讨论了地理空间数据分布与存储模型体系、空间数据在关系数据库中的一体化存储与管理方法、空间数据库引擎技术。

The distributed storage and management of multi scale geographical spatial data is the technical support that we construct distributed network GIS and implement the integrated application of multi scale and multi data types digital geographical information products The paper discusses the distribution and storage model system of geographical spatial data, the integrated storage and management method of spatial data in relation to data base, the spatial data base engine technique, the systematic structure of multi scale geographical spatial information integration management
