Yeah, sorry about that ;-)
All: Are we greed that if it's *definitely* been issued under OGL, a
local authority's data can be used within OSM?
And by 'used' I don't necessarily mean copied directly. I'm overlaying
my LA's PROW data to see what's missing so I can walk & survey it detail.
Please tell me we're agreed that an on the ground survey is best :-)

Thanks everyone for the rapid influx of comments. I've clearly mined a

In my locale, the council's records are overlays onto OS mapping, so
this is what I'm taking away from the conversation:
You should not copy from these maps, but they are useful to get an
idea
of what is missing and can then be surveyed.
Another reason not to copy is that they are not 100% accurate and we
should map what is on the ground

In most cases it cannot be simply incorporated into OSM. The
definitive
maps were drawn onto OS maps, and all I have seen are overlayed
onto OS
maps with the words Crown Copyright.
You should not copy from these maps, but they are useful to get an
idea
of what is missing and can then be surveyed.
Another reason not to copy is that they are not 100% accurate and we
should map what is on the ground. The maps were originally drawn by
parish councils, and not always accurately. For example here in
Shropshire a path is shown passing through a house, built on a
right of
way? No, the house was built in the 1500s, and the pen must have
slipped.
The other advantage of surveying is that we can map the barriers, this
is when OSM can beat OS as a walking map. When you survey the paths,
please map the stiles, kissing_gates, gates etc. That is important
information for many walkers.
