Notes
- Data: Database of British and Irish Hills v18.0
- Relative height, drop, or prominence is the height difference between a hill's summit and the col (lowest point) connecting it to the next higher summit. "Marilyns" are hills with a relative height of 150 metres, and "Humps" have 100 metres. There are some even in the south east of England.
- We use OS mapping for England, Scotland, Wales, and the Isle of Man. Sadly, Channel Islands, Northern (OSNI) and Southern Ireland (OSI) mapping isn't available online, so we use Openstreetmap.
