Subject: Mapping for the disability community

Hello All,

I would like more information on what is needed to make a map and/or image
JAWS accessible.

Also, I believe a technique could be done for the blind/sight impaired by
using a pin table that I saw at a conference, that distributes terrain
models. I sent a link about it to this list a few years ago.  Of course,
the map characteristics would need to be simplified, which is very
possible with GIS symbol replacement. It could possibly be used to teach
letters and braille too.

What data/image/vector formats are read by screen readers?
What types of attributes can they pick up from an image or vector file? 
Is Jaws able to read map-related metadata and in what format?  SVG?

For example, would screen readers be able read the road names and
addresses, that are associated with the lines in a GIS system?
GML?  Are they FGDC compliant?

Also, and this was partly answered before I sent my response...

What are the basic data elements in a map that are useful to the
disability community, and can these be categorized and prioritized?
Also, what types of information that might be attached to map features,
would the disability community want to see?

For example:
Accessible Parking - Attribute - Parking Lot Name, Spaces Available
Points of Access to Buildings - Attribute - Bldg Address?
TTY locations in bldgs

The University of Washington has set a great example for mapping
disability access information, that we have been following.

Apologies for mis-stating.  I should have looked back at my notes and
clarified my memory.
