随着对地观测技术、地理信息技术和计算机技术的快速发展，地理空间数据呈现出多源化、实时化和海量化等趋势，球面离散网格系统作为一种新的数字地球参考模型，它为多尺度、多源异构的地理空间数据集成提供了统一的框架。主要研究了球面离散网格系统为地理空间数据集成所提供的统一框架，并分别讨论了多尺度、多种格式和投影的地理空间数据的集成方法。通过特征归一化处理和构建地名索引服务，试图解决数据尺度不同所带来的挑战，实现海量地理空间数据的动态管理。

With the development of the technology of earth observation , geography information and computer , geospatial data trend to multi-sources, real time and wealth.As a new digital earth reference model , discrete global grid system provides an uniform frame-work for the integration of geospatial data which is multi -resolution, multi-source and isomerism .The uniform framework that the discrete global hexagonal grid system provides for the integration of geospatial data are mainly discussed , with the method of the inte-gration of geospatial data with multi -resolution, net resolution of data , and achieve dynamic management of magnanimity geospatial data.
