Effectiveness of animated choropleth and proportional symbol cartograms for epidemiological dashboards
Epidemiological maps on COVID-19 dashboards were critical to disseminating information during the pandemic, but dashboard creators faced difficulties avoiding common misinterpretation pitfalls that result from varying population density. Furthermore, most dashboards did not include animated maps despite their intuitive visual analogy to the temporal unfolding of events. This study explores the effectiveness of population cartograms as a basis for…
Manual construction of continuous cartograms through mesh transformation
A computer-assisted framework is proposed to support the manual construction of cartograms. The framework employs a joint triangulation, similar to that used in rubber-sheeting, to define a piecewise affine transformation between map space and cartogram space. This guarantees preservation of all topological relations within and among transformed datasets with insertion of a finite number of points. To support intuitive user control of cartogram a…
A heuristic multi-criteria classification approach incorporating data quality information for choropleth mapping
Despite conceptual and technology advancements in cartography over the decades, choropleth map design and classification fail to address a fundamental issue: estimates that are statistically indifferent may be assigned to different classes on maps or vice versa. Recently, the class separability concept was introduced as a map classification criterion to evaluate the likelihood that estimates in two classes are statistical different. Unfortunately…
Cartographic techniques for communicating class separability
In mapping population characteristics, data are usually portrayed as accurate without error. However, many population datasets provide estimates derived from surveys or samples, and a certain level of uncertainty is associated with each estimate. Ignoring estimated uncertainty information in mapping may produce misleading maps and generate spurious spatial patterns. In this paper, we introduce a measure of separability to indicate the likelihood …
Sphere-to-Sphere Projections
An equivalent alignment-preserving projection family is developed to portray a region of the Earth on a spherical surface while altering the proportion of the sphere covered. Shape distortion is evaluated using Airy's criterion and compared to analogous projection onto a planar surface for a range of proportional enlargement factors and for regions varying in central latitude and latitudinal extent. Distortion from projection onto the sphere is f…
Gradation as a Communication Device in Area-Class Maps
This paper proposes a methodology to assess gradation as a cartographic tool for communicating information in area-class maps. The communication model is used as a theoretical foundation, suggesting distinction between errors that occur in encoding and decoding of geographic information. The proposed methodology begins with the determination of a target level of encoding error. Map alternatives are constrained to achieve this target, with gradati…
