Investigating accessibility on web-based maps

This paper presents results of an accessibility evaluation carried out with web-based map applications. Three points of view were considered: experts on accessibility, evaluation tools and final users (partially or totally blind people). The document WCAG 2.0 (Web Content Accessibility Guidelines) provided us with guidelines for evaluation and GQM (Goal, Question and Metric) approach was used to define and set measurable goals. A number of problems was identified and none of the evaluated applications entirely meet the analyzed criteria.
