摘要
本文分析了全球离散格网系统的任意分辨率、层次性和全球连续性特征，指出基于其解决面向全球范围的多尺度、多时相、立体式的地理信息共享与服务的数据组织模型的可能性。结合应用方向比较了几种典型格网划分的优缺点，最终选定基于行列编码的四叉树和GeoSOT格网划分模型作为下一步实验的对象。
The characteristics of arbitrary resolution, multi - hierarchy and the global continuity of the Discrete Global Grid System are analyzed, and the possibility for constructing a new data organization model to realize the multi - scale, multi - temporal and three - dimensional geographic information sharing and service on the global scale is pointed out. The advantages and disadvantages of several typical discrete global grid system subdivision models are discussed, and finally the quad - tree subdivision model based on row and column coding and GeoSOT grid model are selected as the object for further experiment.
