Re: Country maps best practise and examples.

Mobile coverage for a specific frequency is the information being shown. At suburb level it might say 3g coverage 90%, at street level it might say 90% 3g cover. More you zoom out the coverage information is similar but at a higher view. Sighted (mouse) users can scroll around at suburb levels to see other streets coverage level all at real time. This currently is shown in colour. I already know there is issues for showing only in colour.

I hope this clarifies things.

The map must be able to zoom into a street, zoom back up to suburb level, be able to show streets of the near-by suburbs, zoom out to state level and then to the country level. I see this working okay for low vision, keyboard only users and possibly for cognitive disabilities if the map is kept simple. The challenge I see is with screen readers. So if people have examples which they have made accessible. Please let us know.

Particularly for screen reader users, I think it's important to establish exactly what the purpose of the map is ... what is it trying to convey exactly (beyond "showing" the map). Is it to determine what streets (street names/numbers) are in a particular area? List specific points of interest? If it's just a generic "show all roads" that will be quite difficult to convey non-visually (other than providing a non-map alternative that simply lists stuff in text), I would posit.
