摘要: |
现有网络数据可视化中与地理空间信息紧密结合表达的研究较少,难以支撑网络资源测绘数据表达与分析,制约了网络资源测绘数据可视化理解和认知。为此,本文提出了一种与地理空间紧关联的网络空间地图模型。首先,界定了本文网络空间的定义,分析了网络空间与地理空间的关系;给出了与地理空间紧关联的网络空间地图模型及组成要素;最后,详细阐述了与地理空间紧关联的网络空间地图中涉及的网络资源符号体系、多尺度可视化表达和分析应用三项关键技术。本文希望能够为地理信息辅助下的网络空间态势感知提供新的探索方式和研究思路。 |

Abstract: |
There is little research on the tightly combined expression of the existing cyberspace data visualization with the geographical information, which is hard for the expression and analysis of cyberspace resources. It also restricts our understanding and cognition to the cyberspace resources. For this reason, this paper draws on the relevant principles and techniques in cartography and geospatial analysis, and proposes a cyberspace map that is tightly coupled with geographical space. First, we define the cyberspace of this paper and analyze the relationship between cyberspace and geospatial. Then, we propose the concept and elements of cyberspace map that are tightly coupled with geospatial space. Finally, we elaborate the key technologies of the cyberspace map from three aspects in detail, including symbol system of cyberspace resources, multi-scale visualization & expression and analysis & application. This paper hopes to provide new exploration methods and research ideas for cyberspace situational awareness with the aid of geographical information. |
