seconding what @Kate Deibel said - if you want to find out whether your final product is actually useful for a particular group there is no "magic button" substitute that replaces working directly with blind or low-vision users.

if you just want to cover some bases to avoid liability that's a separate issue.

tools like openstreetmap have indoor mapping tools like https://osminedit.pavie.info that may interact with tools like openrouteservice.org and make actual wayfinding simplified....

Hi Kun,

Do you also have a Legend accompanying your floor maps with textual description matching location information (i.e floor number) and labels?
If you do not convert the text into an image it should be accessible.

Best regards,

I am creating a floor map in SVG. I thought I could add alt text to each region so that screen reader could read each region. But apparently not. According to this website: https://www.a11y-101.com/development/svg

All you could do in SVG is add a title and description. Most screen reader won’t go into SVG.

Hi Kun,

If what you want are text labels inside the SVG files for your library floor map, add the text to the images areas but do not convert the text to raster or vector outlines.
Please feel free to provide additional clarification or reach out to me directly, if I can help.

Best,
Guita

Hi Kun,
SVG includes two elements for providing short and long text descriptions: The “title” and “desc” elements. This link on text in an SVG file may be helpful:

Hi

Anyone has experience in creating accessible SVG floor map?  I am wondering
if there is a way to add descriptions in SVG to each block (path or rect).
Or I am being limited to the alt tag in HTML.



Thanks

Kun
