OSM for the blind
OSM is the map for everything and everyone, so some projects have been started to provide accessibility to the OSM services for blind and visually impaired persons.
OSM for the blind is the name of this group of projects.
How to map for the blind
If you want to make the map accessible for blind persons, these are the things to pay attention to:
- Accuracy is important. If you estimate a POI, add FIXME=position estimated to your entry, so the next mapper will check the coordinates
- Learn to know and use the tags for the blind, see below.
- Add POIs that are of interest:
- Public transportation stops with platforms, use tactile_paving=yes/no,
- pedestrian crossings with and without acoustic guidance traffic_signals:sound=yes/no, vibration traffic_signals:vibration=yes/no and sloped kerbs (look at DE:Rollstuhlfahrer-Routing,
- pedestrian crossings with islands crossing=traffic_signals;island crossing=uncontrolled;island
- elevators with or without braille writing or embossed printed letters
- meeting locations of organizations of the blind and visually impaired
- shops for optical glasses, eye doctors and hospital departments for eye diseases.
- POIs that offer special products for the blind.
- POIs that offer special accommodations for the blind like Cinemas with narrator, museums with acoustic / mp3-guides, braille menus, etc.
- If you add POIs, it is better to add buildings and put an exact entrance node at the entrance. Try not to add POIs as the estimated middle of a building.
- If you map house numbers with Karlsruhe Schema, put an exact entrance node at the entrance.
- If mapping streets, add parking lanes, bicycle lanes and footways as lanes with number of lanes and/or width-tag.
- Add surface=* tag to footways - this is appreciated when a white cane (blind man's stick) is used.
- You can check your edits on http://blind.accessiblemaps.org
See the map for the blind: Project blindmap
There is a beta version available of a visual map with map features displayed that are of special interest to blind and visually impaired persons at
note: This map is now MapJumper compatible
A new map for the blind: an interactive audiobook atlas called "Look and Listen Map"
- Oct. 21, Look and Listen Map wins Torsten Brand Preis 2011.
- Online map and routing portal for blind persons, see Look and Listen Map
- Look and Listen map won a prize in the German WissensWert competition for project ideas about open data / open knowledge.
- Programming of the Look and Listen Map has started in 2011 in Paderborn, Germany.
- Sponsors wanted!
I am blind - How can I help ? - Project blindOSM
If you want to support the OpenStreetMap project, here is how you can do it:
- Symbian cellphone with a screenreader (e.g. N80 with Nuance Talks) and Loadstone-GPS from  or
- Windows Mobile cellphone with a screenreader (e.g. with Mobile Speak) and a logging software.
You can donate your tracks
Do the following steps once:
- Get GPSBabel for your computer operating system.
- Go to http://www.openstreetmap.org/user/new and register for an OpenStreetMap user account.
Do the following steps whenever you want to donate a track:
- When you walk, ride or drive around with Loadstone, turn the tracking function on. Choose a filename including:
- When at home, download the files to your computer.
- Use GPSBabel to convert the .nmea files to .gpx.
- Go to http://www.openstreetmap.org/traces/mine and Browse for one of the files, add the description you know from the filename and add "blindOSM" and the parts of the filename mentioned above as keywords. Click the public checkbox to make sure the other users can see your tracks! (I will publish that the tracks with "blindOSM" are collected by blind users and that other users are welcome to create streets from them.)
- Repeat 4. for each file.
- Find the tracks with "blindOSM" as a tag: http://www.openstreetmap.org/traces/tag/blindOSM
- Find the information if it has been worked on your tracks here: blindOSM
- If you collect tracks for streets that are missing in OSM, then make separate tracks for each street and put the street's name in the description.
- Walk up and down on both sides of the street to get a good result.
- Do not start the tracking function until your GPS has at least 5 satellites in view.
- You can check if somebody has worked on your tracks by using the OSM converter on the Loadstone web page.
Other things one can do
- Translate wiki pages to your language.
- Translate http://www.loadstone-gps.com/ to your language and send the files to the owners of the site.
- Get in contact with the local OSM community by searching for your city's name in this wiki.
- Collect POIs in Loadstone and name them well. It is planned to import this information to OpenStreetBugs.
- Join the discussion. Join the mailing list by sending an email to firstname.lastname@example.org.
- Test navigation applications that use OpenStreetMap data. Write to the developers for accessibility improvements. Publish your testing results here in the wiki.
- If you are a developer, get in contact with Lulu-Ann - There are many ideas for small and big projects.
- Take part in the OSMtracker display resolution survey and vote for the option to support screenreaders.
- Put hiking trails for the blind into the map like this one: , marked with "BL".

Help to work on tracks
Find tracks recorded by blind persons at:
You can help to work on them.
IMPORTANT: Please add the status here, when you have worked on the tracks: BlindOSM
- Add relevant tags in your area for the blindmap.
Of course you can also do things from the list for the blind like translating wiki pages (see above).

- (red-green) Some color blind persons can work with OpenStreetMaps better than with Google Maps, because they contain less green. However, grey buildings blend in with pink roads, as people with red/green color-blindness don't have a strong response to red, so for others OpenStreetMaps are harder to use than Google Maps.
