Systematically Evaluating Digital Map Tools Based on the WCAG.

Abstract

This study examines the accessibility of digital map tools in relation to the Web Accessibility Guidelines (WCAG) 2.1, highlighting critical issues for disabled users. Despite the widespread use of digital maps across various professions and daily activities, their accessibility remains insufficient. The research involved a partial Accessibility Conformance Report (ACR) comparison of the top 14 digital map tools, focusing on 15 WCAG criteria particularly relevant to geographic maps. The study expanded definitions for three criteria - 1.1.1 Non-Text Content, 1.4.11 Non-text Contrast, and 2.1.1 Keyboard Accessibility - to better apply them to map contexts. Findings revealed significant accessibility shortcomings, with only one tool (Audiom) achieving full compliance and others lacking adequate text alternatives, proper contrast, and keyboard operability. The discussion emphasizes the urgency for map developers to enhance accessibility, especially in light of upcoming legal requirements like the ADA Title II regulations. Making maps accessible not only aids users with disabilities but also offers business benefits by expanding the user base and fostering innovation. The study provides a systematic evaluation framework and clear guidelines to encourage greater digital map accessibility within an academic context.
