Key Points

The study analyzes how thematic map design practices in academic cartography evolved from 1990 to 2020 using a large, multilingual corpus of journal articles.
Researchers compiled 45,732 articles and extracted 23,928 maps by combining computer vision with large-model-based document parsing, creating a structured dataset for quantitative analysis.
The findings indicate strong similarity between Chinese- and English-language academic maps in structural conventions, including restrained color palettes and centered layouts.
Differences are observed in color richness and compactness, with English-language maps tending toward slightly greater hue diversity while Chinese-language maps historically rely more on neutral hues and integrated layouts.
Over time, both groups show parallel trends such as increased element richness, more frequent legend usage, and greater hue diversity, suggesting institutional convergence dominates over cultural divergence.

Abstract

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 multilingual analysis of thematic map design practices in academic cartography from 1990 to 2020. We compile a corpus of 45,732 research articles from sixteen authoritative Chinese- and English-language journals and extract 23,928 maps using computer vision and large-model-based document parsing to build a structured dataset. Map design characteristics are quantified across three dimensions: map elements, color design, and layout structure. Results show that Chinese- and Englishlanguage academic maps share highly similar structural conventions, typically employing restrained color palettes with neutral dominant hues, low saturation, high brightness, and limited hue diversity, as well as centered layouts with high main-map occupation ratios. Differences exist in that English-language maps show slightly greater hue richness and compactness, whereas Chinese-language maps historically rely more on neutral hues and integrated layouts. Temporal analysis reveals parallel evolutionary trends in both groups, including increasing element richness, legend usage, and hue diversity, alongside stable layout structures. Overall, the findings suggest that academic map design evolution is characterized more by institutional convergence than cultural divergence.
