摘要: 地图集是呈现地表覆盖知识的高效表达工具。然而现有地图集仅面向预定区划的知识内容展示,难以满足用户对不同兴趣区域的个性化需求,从而导致图集实用性较差。另外,传统地图集图幅版面布局主要以不同信息的拼合模式为主,难以体现知识所包含信息的关联性,从而不利于用户较快的理解知识内容。为满足地图应用的个性化和知识服务需求,本文基于三期GlobeLand30数据,进行近20年全球地表覆盖时空变化地图集编研工作。除了制作了从宏观角度反映全球、大洲和国家尺度的地表覆盖分布和变化图幅集,还采用用户交互式选择感兴趣区域的方式实时化生成地表覆盖时空变化知识,并提供用户选择不同的知识可视化表达形式和图-文双向交互功能,从而以更为个性化和易懂的方式展示地表覆盖时空变化知识内容。

Abstract: Atlas is an efficient tool for presenting land cover knowledge. However, existing atlases only present knowledge in given regions so that it is difficult to meet users' personalized and research requirements for different interest regions so as to decrease the practicality of atlases. In adclition, a sheet in traditional atlases is generally divided into different regions containing different information so that the relations of information containing in knowledge are not easy to understand for users. In order to meet the personalized and knowledge-based service needs of map applications, this study designed and produced an interactive knowledge atlas based on GlobeLand30 data. Besides the atlas sheets to represent the spatial and temporal land cover changing from the global, continental, and national scales, the atlas can also support users to select interesting regions and generate related changing knowledge, and provided different knowledge visualization templates and the function of interaction between graphics and text, which can help users to understand the knowledge content better and support customized service.

Key words: knowledge atlas, globe land cover coverage data, knowledge visualization, knowledge organization, interaction design
