This study presents the design of a conceptual software architecture for the development of accessible web maps for visually impaired users. The conceptual software architecture proposed has three components: the database component is responsible for storing the web maps, the accessible web server component is responsible for converting a web map into an accessible web map, and the user side component is responsible for presenting the accessible web map to the user. A web application has been developed that shows the feasibility of implementing the proposed architecture. This application displays accessible web maps that provide additional information for visually impaired users. In addition, the application offers some alternatives for better interpretation of each map element. Visually impaired users receive feedback from the map displayed on the interface using a screen reader. The application has accessibility features based on WCAG 2.0 that facilitate the interaction of the visually impaired users.
