Abstract:

To supplement the deficiency of the latitude and longitude existed as location code, such as complex description, non-regional characteristics and complex computation, a globe spatial grid reference system is constructed based on GeoSOT from Peking University. The grid system, built from a perfect quadtree with one degree, one minute and one second grid, could be fit for air-earth joint action. It designs a simple and practical location coding method, which also supports distance simple calculation. It could realize multi-source spatial data integrated retrieval, and develop methods of efficient code operation, framework of spatial computing, and 3D-earth grid system. Globe Spatial Grid Reference System will definitely play an important role in the future of big spatial data applications.

Key words: globe spatial grid reference system, GeoSOT, latitude and longitude, quadtree

摘要：

为了弥补用经纬度作为地理位置标识存在的描述复杂、无区域特征、计算复杂度高等不足, 以北京大学提出的GeoSOT网格为基础, 构建一套全球空间参考网格系统。该系统以等度、等分、等秒的完美四叉树剖分网格为基础, 建立适合协调空地联合行动的网格体系, 设计了简单实用、可距离计算的定位编码方法, 可实现多部门、多源异构地理空间数据的统一检索, 并发展出高效编码代数运算、地理空间管理与计算框架、三维地球空间剖分框架等新方法, 将在未来的地理空间大数据应用中发挥重要作用。
