地理网格技术标准化的现状分析

Current Situation Analysis of Geographical Grid Standardization

地理网格通过对地理位置进行网格化剖分与编码,可有效表达地球各圈层、各要素的空间位置和相互关系,以提升多源数据融合、管理与应用效率。在梳理国际地理网格技术的标准化现状和应用简况的基础上,剖析了我国地理网格标准化的现状、技术特点以及面临的问题与挑战,为其在多源空间数据的信息集成、共享、分析处理、服务等方面的应用提供参考。

With the grid division and encoding of geographical location,geographical grid can effectively express the spatial location and rela-tionship of various spheres and elements of the earth,which can improve the efficiency of multi-source data fusion,management and application.In this paper,we reviewed the current situation and application of geographical grid technology standardization in the world at first.And then,we analyzed the current situation,problems and challenges of geographical grid standardization in China,which could provide reference for the ap-plication of geographical grid technology in information integration,sharing,analysis,processing and service of multi-source spatial data.
