摘要/Abstract

摘要： 随着空间和对地观测技术的飞速发展，建立一个适应全球的多源、多尺度、多时相跨平台统一数据组织的网格框架具有非常重要的意义。当前地理空间数据的生产、维护分散在不同单位，且采用的数据网格标准各异，造成了部门或系统之间、不同历史阶段之间标准不统一。本文针对高分专项地理空间信息保障库对数据资源全局展示、关联检索和模版应用等综合服务展示需求，基于GeoSOT网格与编码理论体系，提出了“地理空间信息全球统一网格化编码管理”的数据剖分组织解决思路，并进行了系统分析、研究与设计。通过试验证明，基于GeoSOT虚拟一张图的数据组织管理方法能够显著提高地理空间信息保障服务系统的整体应用效能。

Abstract: With the rapid development of the space and earth observation technology, it is important to establish a multi-source, multi-scale and unified cross-platform reference for global data. In practice, the production and maintenance of geospatial data are scattered in different units, and the standard of the data grid varies between departments and systems. All these bring out the disunity of standards among different historical periods or orgnizations. Aiming at geospatial information security library for the national high resolution earth observation, there are some demands for global display, associated retrieval and template applications and other integrated services for geospatial data. Based on GeoSOT grid and encoding theory system, "geospatial information security library information of globally unified grid encoding management" data subdivision organization solutions have been proposed; system-level analyses, researches and designs have been carried out. The experimental results show that the data organization and management method based on GeoSOT can significantly improve the overall efficiency of the geospatial information security service system.

Key words: geospatial information, GeoSOT grid, grid encoding, multi-source data association, multiscale data
