Abstract: Map generalization is a fundamental technology in cartography.As the concept of maps evolves,map generalization also needs to expand its conceptual framework and methodologies to meet the requirements of pan-map presentation and production.This paper discusses the expansion of map generalization in terms of generalized objects,content abstraction,and presentation dimensions within the conceptual framework of the pan-map.It also explores the application of traditional map generalization methods to the creation of various pan-maps,such as flow maps,cartograms,and thematic maps.These applications broaden the scope of existing cartographic generalization methods and provide valuable references for further exploration in the field.

Key words: flow map, cartogram, tag map, visualization
