Evolving Thematic Map Design in Academic Cartography: A Thirty-Year Study Based on Multilingual Journals
Zhiwei Wei, Chenxi Song, Tazhu Wang +4
Thematic maps play a central role in academic communication, yet their large-scale design evolution has rarely been examined empirically. This study presents a longitudinal and mul…
Optimized 3D Point Labeling with Leaders Using the Beams Displacement Method
Zhiwei Wei, Nai Yang, Wenjia Xu +4
In three-dimensional geographical scenes, adding labels with leader lines to point features can significantly improve their visibility. Leadered labels have a large degree of freed…
Circular cartograms via the elastic beam algorithm originated from cartographic generalization
Wei Zhiwei, Ding Su, Xu Wenjia +3
The circular cartogram, also known as the Dorling map, is a widely used tool for visualizing statistical data. It represents regions as circles with their areas in proportion to th…
From river flow to spatial flow: flow map via river flow directions assignment algorithm
Zhiwei Wei, Su Ding, Yang Wang +2
Flow maps are thematic maps that visualize object movements across space with a tree layout, in which the underlying tree structure is similar to a natural river system. In this pa…
