Visual Contrast & Hierarchy Relations Across Multi-Scale Map Displays — P. William Limpisathian

Visual Contrast and Hierarchy Relations of Cartographic Features Across Multi-Scale Map Displays: Map Evaluation Results P. William Limpisathian, University of Oregon; Cynthia A. Brewer, The Pennsylvania State University Visual contrast is a fundamental principle employed in cartographic design to highlight foreground elements on maps. However, limited software resources and research exist on how to maintain consistent visual contrast and hierarchy relations across map scales. This task is especially challenging in map series that are constrained by a color and layout template that affects fore-to-background feature recognition. Four combinations of lightness contrast, ten hue contrast combinations, and two line-width contrast levels are tested in combination with six basemap locations, each with two layout variants, generating 960 individual test maps or 480 map pairs. The results of aesthetic and hierarchy evaluations of five map pairs by each Amazon Mechanical Turk worker are analyzed with a Friedman non-parametric test and linear regression models. The project lays the empirical foundation for an application that provides users with map design schemes that preserve the cartographer’s intended visual contrast and hierarchy relations. This presentation was made at the 2017 annual meeting of the North American Cartographic Information Society (NACIS) in Montréal. For more information on NACIS, check out http://NACIS.org.
