基于全球三维空间网格的时空地理数据组织方法

The Method of Spatiotemporal Geographic Data Organization Based on Global 3D Spatial Grid

为解决海量、多源、异构时空地理信息数据高效组织存储、无缝关联融合及其深度挖掘分析数据知识的难题。基于Geohash算法,按照等分法的思想,在球面网格剖分的基础上,加入高程维度的剖分,建立全球多层级、多尺度的三维空间网格体系,并赋予每个网格单元全球唯一网格编码,实现陆、海、空、天和地下全域空间网格位置的统一标识,大幅降低时空地理信息数据组织存储、融合与管理的复杂程度,提高查询检索与分析应用效率。

In order to solve the problem of massive,multi-source,heterogeneous spatio-temporal geographic information data efficient organization and storage,seamless association fusion and deep mining and analysis of data knowledge.Based on Geohash algorithm,according to the idea of bisection method,on the basis of spherical grid generation,elevation dimension generation is added to establish a global multi-level and multi-scale three-dimensional spatial grid system,and each grid cell is given a unique grid code in the world,so as to realize the unified identification of land,sea,air,sky and underground spatial grid location,and which greatly reduces the complexity of spatiotemporal geographic information data organization,storage,integration and management,improves the efficiency of query retrieval and analysis application.
