Abstract: With the advancement of information and communication technology (ICT), a large number of new visualization types and techniques of map representation have been developed, and the term of pan-map is proposed due to these new cartography visualizations. However, the map design and production still greatly depend on map makers' experiences and professional skill, which cannot meet new requirement in ICT era. In order to enhance the objective and automatic levels in the process of map design and production in information era, and keep developing of map theories with the new techniques of cartography visualization, this paper aims to develop the visualization mechanism of pan-maps representations. In this paper, the relationships between requirements of pan-map representations and visualization dimension types are constructed based on visualization dimension system and map functions. An analysis on the typical map visualization of different visualization dimension types has been conducted. The visualization mechanism of pan-maps has been constructed and follows the strategy "analysis of representation requirements → combination of visualization dimensions → determination of visualization representation types → map visualization". This study is helpful to the developments of cartography research and applications, the popular map design, representation, and production.
