This page differs from the German page.
HaptoRender is planned to be a renderer that uses OSM data to create tactile maps for blind and visually impaired persons.
HaptoRender will have several advantages compared with commercial tactile maps:
- Maps can be created for any village in the world - not only for city centers of interest for tourists
- Maps can be created from current geodata, not only one edition in many years
- Maps can vary, it is possible to create maps with additional contrasts for visually impaired persons
- Maps are cheaper, because there will not be any license cost for the map data.
- If one part of a map is obsolete, the part can be reproduced.
The HaptoRender project was started in April 2009 by Lulu-Ann.
- 2013 Christian Schuhmann publishes Bachelor Thesis about automatic 3D plastic printing of maps.
- 2012 Daniel Hänßgen publishes master thesis about automatic embossing of maps on paper (Youtube, see "Daniel Hänßgen")
- 2010-03-04 Lulu-Ann will speak about accessibility at the FOSSGIS 2010 in Osnabrück, Germany.
- 2009-07-12 Lulu-Ann held a lightning talk about accessibility at the State of the Map 2009 in Amsterdam, Netherlands.
- First tactile map prototype out of copper was created by Bahnpirat. It was shown and touched at SOTM 2009 in Amsterdam.
Already produced maps
Reinhard-Niether-Krankenhaus in Wilhelmshaven, Germany
This is the first known tactile map based on OSM data published on May 12, 2009. It is a copper sheet with the size of an DIN A4 paper sheet. This was shown (and touched) at the SOTM 2009 in []Amsterdam. Contact Bahnpirat for more details on this.

HaptoRender Project Status
There are already two different ideas how to create tactile maps from OSM data.
- Size and scale of map tiles are planned.
- Needed file format is known (99%).
- First map files are created. Improvement needed.
- Prices are queried from one potential producer for prototype
- Price for a production machine is known. Pretty expensive, maybe leasing?
- Braille true type font with surely usable license is now available.
- Map style for few objects is fixed.
- First map is created!
- Map style for tags of special interest for the blind are in work.
- HaptoRenderPreCheck is not startet.
- Displaying of license and OSM on product in braille writing and/or embossed printed letters is not clear.
Current to dos
- We are looking for a braille .ttf (True Type Font) that complies with CC-BY-SA license. Who can help?
- Font needs to be replaced by braille. (OK for Latin, java library liblouis should do for all languages)
- Rules shall be created.
- An example legend exists.
- Patterns/ textures need to be created for areas (forest, water etc.)
- Symbols are needed for bus stops etc.
- An additional sheet with the legend needs to be planned.
- An legend must be created with all symbols
- A street list needs to be generated for each created tactile map
- HaptoRender will not use abbreviated braille, but full braille writing (de:Blindenbasisschrift statt Blindenkurzschrift oder Blindenvollschrift).
What is in the map
A tactile map has a larger scale (1:1000) and shows less details than a visual map, but adds some tags that are of special interest for blind people.
Rendered in HaptoRender
This part has been moved to HaptoRender/Rendering_Rules
All features displayed on the visual map of features for the blind: blindmap.
Not in the map will be
The physical production of a tactile map usually causes costs. Before the HaptoRender can create a tactile map creation file of high quality, the desired area shall be checked for
- common tagging mistakes
- unknown tags
- density of worthfull tags
- tags that are known to cause troubles (to be defined)
Therefore a HaptoRenderPreCheck shall be created.
Ordering a map
If you want to be one of the first to order a tactile map from HaptoRender for yourself or as a present, please leave your Nickname and desired center coordinates here. Note: A tactile map tile from HaptoRender is planned to be for a 200m x 200m area, which is 20cm x 20cm in mapscale.
This is not an order, just a poll for interest!

These devices might be suitabel to create tactile maps from OSM:
for plastic or rubber
- Machines that can laser rubber stamps
- Rapid prototyping machine with powder printing method
- plastic extrusion rapid-prototyping machine (e.g. RepRap, UP! 3d Printer)
for plastic, wood or metal
- CNC machine (different file format!)
- waterjet (takes dxf gnerally)

Side effects: Tattoos
You could use a HaptoRender Map for making a temporary tattoo. Don't forget to request a mirrored with printed letters instead of braille writing map!
