I would use the 'Open Data from official sources' to confirm the 'on the ground' public signage. A conflict should lead to further investigation/thought.

A very interesting comment, considering the lengths we seem to go to to avoid importing Open Data from official sources.

    Just a comment that I'd be wary of "No hunting", "Hunting
    allowed", or "Private property", or other signs on the ground that
    can actually be placed by anyone, whether or not they are legal. A
    problem that I've encountered more than once is a private property
    owner putting out what appeared to me to be an illegal sign, like
    putting a home-made speed limit sign on the small street that goes
    by their house. A similar problem that I've heard about is
    business owners putting out "No parking", "Customer parking only",
    "Private beach", and similar signs which were made to look
    official but actually were not approved by any government agency.
    So signage that you see in public is not always trustworthy, and I
    would be cautious about relying on it. Relying on official
    databases seems to me to be preferable to relying on signage.

        I'm not a hunter, but I have encountered a lot of "hunting
        forbidden" signs in different places, sometimes every few
        meters apparently delimiting an area. While I didn't map them
        at the time, I guess I could have done it without having
        deeper insights into the hunting business, simply by looking
        where the signs were.

        What you ask for is desirable, but I would not make it a
        requirement. In any field you can provide better mapping if
        you know more about the topic, but this hasn't led us to only
        ask specialists for their contribution.


        cheers,
        Martin
