This is OS mapping. In some areas, OpenStreetMap shows more footpaths
Spatial NI has online OSNI mapping. Click "Basemap Gallery" (4 squares icon at the top).

The other photos have been geo-tagged as on or around the summit. For less busy mountains, it can be a little hit and miss.
- 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.
