A Comparison of Map Usability via Bivariate Ordinal Analysis
A Comparison of Map Usability via Bivariate Ordinal Analysis
SSS2023-01
Abstract
Nichols et al. (2023+) present a study where respondents compare usability of two types of geographic maps: satellite maps, which display details such as landmarks and terrain, and simplified road maps. Ordinal responses measured self-reported familiarity with the maps and accuracy in finding a respondent’s home and neighboring homes. The present report compares satellite and road maps for each of the two characteristics using a bivariate ordinal regression model. This model is based on a latent bivariate normal random variable whose parameters are used to test the hypothesis that one of the map types is preferred over the other. Several additional characteristics are considered as potential covariates and found to make little practical difference in terms of the observed counts. It is seen that satellite maps are preferred to road maps in both familiarity and accuracy.
