Open questions
Other 'cliff' definition questions
Some open questions. Please discuss on the talk page:
- Do we want to use this tag not only for natural cliffs, but also for man-made cliffs? We do also have barrier=retaining_wall
- Is it important for a cliff that you can see the naked rock, without soil and plants on it, or can a very steep forest floor also qualify as a cliff? Alternatives might be to map it as barrier=slope, natural=slope or barrier=earth_bank.
