[accessibleimage] maps for the blind

Hi all,
My apologies if this has already been discussed here or if it isn't apropriate for the list, but after reading the messages about production of maps and someone mentioning in an article that they can't distinguish a curve, etc, I thought I should post.
I'm just curious. I'm a totally blind pedestrian who has traveled both with cane and dog guide. I would say a good percentage of the time I am aware of any alteration in direction of travel or even subtle changes. I find it helpful to have maps that depict whether or not the path is straight or angles. I'm not alone, am I?
