摘要: 地球空间网格是将地球空间区域剖分成不同尺度单元的空间参考系统。网格编码利用地理空间位置的结构化索引表达技术,将代码分配给地球空间网格系统的每个网格单元,实现网格位置的统一标识。对照统一规则递归剖分形成的多层次、多分辨率全球的地球空间网格系统编码的要求,本文在分析当前地球空间索引标识技术方法的基础上,探讨地球空间网格编码方案,以实现地球空间网格单元的统一标识,并可通过代码描述网格单元空间位置,反映网格单元间的空间关系。

Abstract: The geospatial grid divides the geospatial region into spatial reference systems with different scale grid units. Grid coding uses the structured index technology of location to assign identifier to each grid of geospatial grid system, so as to realize the unified identification of grid location. This paper contrasts the identification requirements of the multi-level and multi-resolution global mesh grid system formed by nesting and sectioning according to the uniform rules,based on the analysis of the current geospatial index identification technology, discusses the coding scheme of the global mesh grid system, and proposes a set of geospatial grid identification system which realize the unique identification of the global grid units, describes the spatial position of grid cells,and reflects the spatial relationship between grid cells.

Key words: geospatial grid, spatial reference frame, grid unit, mesh, grid coding
