摘要
针对目前空间信息编目多样、缺乏全球统一编目体系的现状,借鉴地理空间信息分类框架,结合地图分幅拓展球面剖分理论,提出了基于EMD的空间信息剖分一体化编目模型。在此基础上,设计了统一剖分编目中间件,搭建了全球空间信息统一剖分编目数据的管理框架。基于EMD的空间信息剖分一体化编目模型为实现空间数据的全球化、层次化和规范化管理奠定了理论基础。
Against the present of the multiplicity of cataloguing of geospatial information and lack of a uniformed cataloguing system of global geospatial information,in this paper,by using the geospatial information classification framework for reference,according to the Extended Model of mapping division,the subdivision integration cataloguing model of global geospatial information is put forward.On this basis,concept of unified subdivision cataloguing middleware is introduced,and the management framework of global geo-spatial information integrated subdivision cataloguing is designed. The research indicates that the sub division integrated cataloguing model of global geo-spatial information based on the Extended Model of mapping division provides a solid theoretical basis for the hierarchical and standardized management of global geospatial data.
