OS Map

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).

OS	Ordnance Survey (OS) mapping covers England, Wales and Scotland - not Northern Ireland or the Channel Islands. Isle of Man is 1:50K only. Legend : OS 1:25K pdf, OS 1:50K pdf. There are paper 1:25K maps for both Isle of Man and the Channel Islands
OSI, OSNI	OSI and OSNI produce paper 1:50K and some 1:25K maps. OSI isn't online. OSNI (then Basemap Gallery / 4 squares icon, then 25K or 50K)
OpenStreetMap	OpenStreetMap is an opensource global crowd sourced map. It is better at showing footpaths than the OS in some places.

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 v18.2
Maps: 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.
