中文摘要：

通过梳理近十多年来地球剖分格网的相关研究文献,从剖分建模（四边形剖分、等积剖分和立体剖分）、编码计算（层次编码运算、填充曲线编码运算和整数坐标编码运算）、质量评价（评价准则、评价因子和层次传播趋势）及典型应用（政府机构应用、商业系统应用和行业领域应用）等4个方面,对该领域研究进展进行了系统的分类分析,较为详细地给出了不同格网模型的结构特点、适用模式及其存在的不足。最后总结出地球剖分格网在理论基础完备性、格网计算高效性及格网质量可靠性等方面研究的前沿问题。

英文摘要：

By analyzing the related literatures on the earth tessellation grid（ETG）in recent 10 years,the research achievements in this field are systematic reviewed in four aspects,i.e.the earth subdivision modeling（include quadrangle subdivision,equal-area subdivision and 3Dsubdivision）,encoding computation（include hierarchical encoding computation, filling curve encoding computation and integer coordinate encoding computation）,grid quality assessment（include evaluation criteria,evaluation factors,and propagation trend in diffferent levels）and typical applications（include government agency applications,business software applications and industry applications）.The structural characteristics,applicable models and their shortcomings in the different grid models are given in details.Finally,some advanced academic problems in the ETG are given based on the completeness of basic theory,the efficiency of grid computing,and the reliability of grid quality.
