Abstract

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
