Sponsors

The OpenStreetMap foundation was funding the development of this project in their first round of the microgrant program in 2020. It was done as part of making tactile maps based on OpenStreetMap data, for blind or visually impaired children.

If anyone else is also interested in supporting this project via funding - let me know (opening a new issue is also OK) :)
