Source: Road maps can present accessibility challenges. In the best practices below, we are addressing ways to improve the accessibility of road maps. Floor plans present a different set of challenges, and can best be handled by in-person assistance, or perhaps a 3D model. Maps | Accessibility Guidelines
- Text-based directions: If the map is used to provide directions to a location, make sure to also provide text-based directions, or a link to text-based directions adjacent to the map.
- Alt attributes: If you are using a static image for the map, make sure to include a descriptive alt tag. Embedded maps, such as Google Maps, should include a
titleattribute. (See below for an example).
- Multiple locations: If you are using a map to display multiple locations, provide a text list of locations.
- Color and contrast: If a map includes color coded regions, make sure that there is sufficient contrast between the text and the background, and that color coding is accessible for users with color-deficient vision. A good test is to see if the map is still usable in black and white.
- Consistency and simplicity: Keep maps consistent and simple in their styling.
- 3D or tactile version: You may want to have a tactile map available for non-sighted users.
