Visualization and Analysis of Cyberspace Metaphor Gosper Map

In recent years, with the continuous expansion and deepening of human geospatial awareness, cyberspace has become a new dimension of human life. Cyberspace is an inevitable product of the development of the Internet and information technology, a deepening and expansion of human geospatial awareness, and a new frontier that affects national security. It has become the fifth dimension of space that countries are concerned about. The cyberspace map is an important tool for understanding abstract and complex cyberspace, and it is also a new research direction and hot topic in the field of cartography. In view of the current problems in network space visualization technology, such as the inability of node-link visualization methods and geographical space layer overlay visualization methods to analyze multi-level topological relationships of network space nodes, as well as the overlap of elements in the above methods, this article comprehensively applies metaphorical thinking, Gosper map technology, and Level of Detail technology to study the metaphorical expression and analysis of network space elements, and proposes a method for constructing cyberspace metaphorical Gosper maps and topographic maps. This article first reviews the current research status of cyberspace map visualization, points out the problems in cyberspace visualization. Then, it describes the methodological principles of expressing network space elements based on metaphorical thinking. Secondly, this article proposes a method for constructing cyberspace maps and topographic maps. That is, firstly, combining the topological hierarchical relationships of network space nodes with the first law of geography to construct a mapping relationship between network nodes and Gosper curve leaf nodes. Then, based on Gosper leaf nodes, a Gosper map with nested face domains is constructed. Finally, combining metaphorical thinking with the similarity relationship between map visual elements and network space elements, multi-scale cyberspace metaphorical Gosper maps and topographic maps are constructed. Finally, based on two sets of network space asset data, we carry out construction experiments on cyberspace metaphorical Gosper maps and topographic maps, verifying the effectiveness of the proposed method. At the same time, we design quantitative analysis experiments for evaluating three visualization methods based on the Analytic Hierarchy Process (AHP). We analyze and mine the characteristics of network space assets from three aspects: network space node distribution, topological structure analysis, and critical terrain analysis. These characteristics are used to demonstrate the expressiveness and cognitive effectiveness of cyberspace metaphorical Gosper maps. Quantitatively speaking, our method outperforms the other two visualization methods in all five evaluation indicators. © 2024 Science Press. All rights reserved.
