摘　　要：提出了一种基于对象存储的空间对象集群存储系统(geospace object store,GOS),为空间数据的存储与管理提供了一种新的解决方法。在GOS系统中,实现了在逻辑层对面向对象空间数据模型的支持,使得数据模型映射得到简化。同时,对象存储本身具有的并行性使得系统具有并行的查询处理功能,使得空间数据查询处理这一计算密集型操作在GOS中得到很好的解决。A cluster storage architecture called as GOS for spatial object based on objectbased storage is presented, which providing a new method to storage and management of spatial data . GOS extends the idea of object-based storage to repartition the function of data- base server and storage devices. In GOS, the storage device performes to directly access to spatial data based on object-oriented model while the server performe some administration for spatial object such as spatial query, spatial index,transaction processing and etc. This architecture promotes the scalablity and performance of the spatial database system. And the GOS support the object-oriented spatial data model on the logical layer to simplify the data model map and the parallel spatial query to improve the performance of spatial data query.
