摘要 针对地理空间数据大数据分布式网络存储管理的地理网络位置搜索问题,从地理网络地址的域名角度,基于2n一维整型数组的全球经纬度剖分格网(GeoSOT)框架提出一种具有地理涵义的空间信息存储网络空间域名地址,即Geonet域名,以统一标识地理空间数据的空间区域位置与计算机存储网络的电子方位,实现用户访问的区域范围、地理空间数据所属地域范围与空间信息存储主机之间的一致性空间关联。 Aiming at the geographic network location search problem of the distributed network storage and management of geo- spatial big data,a kind of geographic domain name of spatial information storage network, namely Geonet domain name, is put forward based on the geographic coordinate subdivision grid with one dimension-integral coding on 2n-tree(GeoSOT). By means of the Geonet domain name to identify the regional location that geospatial data belong to and the electronic direction of comput- er storage network in a globally unified way, it can achieve the consistent spatial association among the area coverage of the user access, the geographic range of spatial data,and the storage host of soatial information.
