Quantitative Approach for Assessing Infographics in Atlas Cartography

Infographics have become a widely utilized concept in contemporary cartography for visualizing a wide range of data. Despite this, there is a lack of comprehensive scholarly studies addressing the theory of infographics, and cartographers have not yet established a precise definition or unified classification for them. Consequently, cartographic production lacks clear rules and methodologies for systematically incorporating infographic elements. This paper introduces a systematic approach for precisely quantifying and evaluating static cartographic products from the domain of atlas cartography with a focus on their infographic style. The proposed methodology was validated through practical assessments of map samples from various atlases, which were compared with samples of infographics. Case studies analysed input patterns related to spatial components, visualization attributes, and additional design elements. Four indicators-area coverage, graphic load, visual attractiveness, and colourfulness-were defined and quantified by using of GIMP graphic software and recalculated through predefined mathematical formulas. The resulting values provide a quantitative description of tested images in terms of their infographic style. This innovative methodological approach contributes to the unification of contemporary approaches for defining and assessing infographics in maps, atlases, and broader cartographic production.
