This is an attempt at creating a map layer showing roads suitable for "gravel" riding (whatever that means, but people usually talk about wide tired drop bar bikes). that can be rendered on top of any base map.

To do that, we forked CyclOSM and kept removing and changing styles until we arrived at something that suited our needs. Kudos to them for the clean code structure and open sourcing their work!

This style is based on the CyclOSM, which is licensed under BSD-3-Clause license. Everything (be it icons or code) not listed explicitly below should be consider as available under this license.

The contours and elevation lines render is based on the very good work and code available from OpenTopoMap.
