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).

Try disabling your ad-blocker if the map doesn't appear.

~~Bing~~	[2025-04] Removed as Bing's API is being switched off. The replacement doesn't have OS Mapping
OpenStreetMap	Switch to: OpenStreetMap - global, free, volunteer created maps. We use the OpenTopo map tile server.
~~Google~~	[2025-04] Removed due to pricing changes. It would no longer be free for us.
OS Data Hub	Switch to: OS Explorer 1:25K, Landranger 1:50K, "road atlas" 1:200K.
	Change map size: full screen, normal
	Print. Select (landscape) or (portrait). Hints: Use 'Print Preview'. You may need to reduce scaling ('shrink to fit'), and remove headers / footers / borders.
	Move the map to my location
	When zoomed in, click a place to get postcode
	Tweets and Instagrams near here
	(for routes) Show waypoints with distances.

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	OSNI and OSI produce paper 1:50K and some 1:25K maps. Only OSNI is online : OSNI \| Basemap Gallery (4 squares icon) \| 25K or 50K.
OpenStreetMap	OpenStreetMap is an opensource global crowd sourced map. It is better at showing footpaths than the OS in some places.

Please tag your photos and upload them to the British and Irish Mountains group on Flickr

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.

Notes

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.
