摘要
目前网络空间地图缺少完整的要素体系和反映网络空间本质的地图数据模型,在表达网络空间多维信息方面能力有限,也无法满足不同的网络空间表达需求。在分析网络空间地图要素的基础上,将网络空间视为三维的信息网络世界,设计了面向网络空间表达的地图层次模型与数据存储结构,分析了数据处理的流程与关键技术。该模型能够适应不同表达需求,为网络空间多维信息可视化提供底层支持。
There is no complete system of map elements or map data model matching the essence of cyberspace at present.Besides,its capability in expressing multidimensional space information cannot meet different demands of cyberspace expression.To solve this problem,the elements of cyberspace were incorporated into one system as much as possible based on the analysis of their features.And then,a hierarchical model and a data structure for cybermap were designed by regarding the cyberspace as a three-dimensional information network world.At last,the process and the key technologies of data processing were analyzed and verified by an experiment with the available data,which also confirmed that this data model could adapt and support different expression demands of multidimensional information of cyberspace.
