> What specifically have you found lacking in OSM compared to OS? The ability to pick two peaks in the lakes in the more rugged area, and to see enough detail of the land (rather than paths) such that I can see whether it is possible to navigate between them. I.e. how granular does the waterways go? Are crags and cragginess fully shown? Are ancient stone walls shown? Do the contours show sufficient detail to indicate a stream that in a different season may be following but isn't considered a waterway all year round? Open Street maps allow me to read the paths, roads, main waterways. Ordnance survey allow me to read the land.
