Re: query on the alternative map widget

Hello,
Representing geographic information to convey spatial relationships
non-visually is extremely difficult, and there is no comercial tool out
there to do this yet.
I have been building a web map plugin that displays geographic map data
visually, in audio, and textually for the last 4 years, and it's starting
to become slightly usable.
Please send me an email if you would like to talk more.
The current methods are: to show data in either a table, alt-text, by doing
an address search and show the nearest locations to someone, or by
providing turn-by-turn directions to a location.
These are the state of the art methods currently.
Thank you,
