传统的集中式数据库、文件系统已经不能有效地处理海量增长数据的存取和管理，而需要采用分布式存储。同时，伴随着对空间信息研究的快速发展，地理信息系统应用逐步走入人们的生活。针对空间数据的存取问题，本文结合数据注册中心和World Wind Java ，实现对空间数据进行存取。首先利用元数据与数据分离的分布式存储方式，以KML来统一组织和管理各种空间数据属性，实现对空间数据的存储，最后用World Wind Java实现对空间数据的读取和展示，以便对采集的空间数据进行有效的存取及为行业应用提供服务，以充分发挥数据的作用，大大减轻对空间数据存储的负担。

Traditional centralized databases and file systems cannot effectively handle the massive growth in data access and man -agement, and are needed to adopt a distributed storage .Meanwhile , along with the rapid development of spatial information , GIS applications gradually come into people’ s lives.For spatial data access , this paper combines the data registration center with World Wind Java to achieve the spatial data access .First, by using the separately distributed storage way of metadata and data , KML is taken to organize and manage variety of spatial data attributes to realize the spatial data storage ,and finally , World Wind Java is used to implement the read and display of spatial data , in order to effectively access the collected spatial data ,provide services for applications , give full play to the role of data , and greatly reduce the burden of spatial data storage .
