摘要 球面离散格网系统是一种能够一体化表达空间位置和测量精度的新型空间数据模型。在分析其优点的基础上,提出利用球面六边形格网系统组织多源、异构空间数据的基本思路。对其中涉及的高精度离散格网系统设计、层次格网编码与索引方案、实体表达与数据重组、实体查询与分析算法等关键技术提出了解决方案。通过原型系统验证了其可行性。 The discrete global grid system (DGGS) is a new class of spatial data structure which represents location and precision of geospatial data synchronously. By analyzing the advantages of DGGS, the idea was presented which integrated multisource and heterogeneous geospatial data using hexagonal DGGS. Correlative key techniques such as high precision grid system, hierarchical grid coding schema, grid index algorithm, grid entity expression model, grid searching algorithm were studied and validated by the prototype system.
