网络空间“测”与“绘”

Cyberspace Surveying and Mapping

网络空间测绘已经成为各领域普遍关注的热点问题。其核心任务是探明网络空间组成要素,分析网络空间现象规律,绘制网络空间结构。网络空间测绘的研究存在概念术语多样、研究框架不统一,要素及规律的认识不清晰,网络空间地图表达方法不规范、缺乏统一标准等问题。在系统梳理各领域对网络空间测绘研究现状的基础上,分析了各领域对网络空间内涵的共性认识;从网络空间的空间特性、地理特性和人文特性出发,剖析了从测绘地理学角度研究利用网络空间的特点和优势;提出了网络空间测绘的研究框架,重点描述了网络空间“测”与“绘”的核心内容和关键技术,并阐述了其与实景三维、数字孪生及元宇宙之间的关系;将网络空间“测量”分为狭义的和广义的网络空间测量,指出其缺少从整体角度对网络空间特征测量和缺乏针对人在网络空间活动现象和规律的测量研究;从网络空间认知需求出发,提出了网络空间地图概念模型和分类;从网络空间坐标系、“地理-网络”关联映射、网络空间地图表达方法等方面重点描述了网络空间地图制图的关键技术,系统分析了网络空间地图表示方法及其适用性;最后,对网络空间顶层概念、网络空间建模方法、网络空间地图理论与方法以及网络空间地图应用场景设计等需要重点研究的关键科学问题和关键技术进行了展望。

Cyberspace surveying and mapping has become a hot research topic of widespread concern across various fields.Its core task involves surveying the components of cyberspace,analyzing the laws of cyberspace phenomena,and mapping the structure of cyberspace.Research on cyberspace surveying and mapping faces issues such as diverse conceptual terminologies which is lack of unified research frameworks,unclear understanding of elements and laws,non-standardized methods of cyberspace map expression,and the absence of unified standards.Based on systematically reviewing the current status of cyberspace surveying and mapping research across fields,a common understanding of the essence of cyberspace has been analyzed.Starting from the spatial,geographical,and cultural characteristics of cyberspace,the features and advantages of studying and utilizing cyberspace from the perspective of mapping geography are dissected.A research framework for cyberspace surveying and mapping is proposed,focusing on the core content and key technologies of"surveying"and"mapping"in cyberspace,and explaining its relationship with 3D Real Scene,Digital Twins and Metaverse.Cyberspace surveying has been divided into narrow and broad senses,pointing out the lack of holistic measurement of cyberspace features and the lack of research on measuring the phenomena and patterns of human activity in cyberspace.From the perspective of cyberspace cognitive needs,a conceptual model and classification system for cyberspace maps have been proposed.Focusing on the cyberspace coordinate system,"geo-cyber"correlation mapping,and methods of expressing cyberspace maps,the key technologies for creating cyberspace maps are described in detail,and the methods of representing cyberspace maps and their applicability are systematically analyzed.Finally,key scientific questions and critical technologies that need focused research,such as the top-level concepts of cyberspace,cyberspace modeling methods,theories and methods of cyberspace maps,and the design of application scenarios for cyberspace maps,are discussed.
