<div dir="ltr">I got in touch with Chris Crocker who is listed on the DoBIH homepage as a contact (and as it turns out is a very friendly and knowledgeable person). I'm quoting here his initial response (with permission to share it) to further discussion:<div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><span style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">We would be happy to see DoBIH data used in OpenStreetMap. One of the motivations behind the creation of the DoBIH in 2001 was to resolve conflicting sources of information on the web by providing a database that we hoped would be definitive. We've had some success as two-thirds of hillwalking websites and all the current smartphone apps take data from the DoBIH.</span><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><span style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">I don't have a problem with signing your document but I'll run it past the other editors.</span><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><span style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">I don't believe you need any other permissions to use data from the DoBIH. OS maps, being creative works, are subject to Crown copyright and OS requires an acknowledgement for their reuse, but I have always understood that heights and grid references are scientific fact and as such are not copyrightable. Certainly there are hundreds of commercial publications in the hillwaking world that tabulate such data. None of those that I've read do more than mention OS maps as the source of their data. The OS data we use is derived from the maps on </span><a href="http://geograph.org.uk/" target="_blank" style="font-family:Tahoma;font-size:13px">geograph.org.uk</a><span style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"> which gives OS mapping at all scales from 1:250,000 to 1:10,000. According to the site the Geograph maps are licensed under the OS OpenSpace Developer Agreement. I note that your Contributors page credits Ordnance Survey OpenData. Other heights and grid references are derived from the Environmental Agency's LIDAR surveys which are freely available on the DEFRA platform, from detailed hill surveys conducted by ourselves and third parties who supply data to us, and from numerous walkers who submit 10-figure grid references (these are responsible for over 60% of summit GRs). We acknowledge all sources and contributors in the Database Notes as you have observed.</span><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><span style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">You might have noticed that our popular Hill Bagging website, which hosts the interactive version of the database, recently added links to OSM on each hill's data page. See for example </span><a class="gmail-m_-1208834652021340179moz-txt-link-freetext" href="http://www.hill-bagging.co.uk/mountaindetails.php?qu=S&rf=278" target="_blank" style="font-family:Tahoma;font-size:13px">http://www.hill-bagging.co.uk/mountaindetails.php?qu=S&rf=278</a><br style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px"><p style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">I expect the DoBIH could contribute much to OSM, but personally I am too busy maintaining the DoBIH to do so myself! I probably speak for the other editors too. I believe one of our users, who goes under the name of <span style="color:rgb(49,5,0)">Talkytoaster on your forum, has contributed to OSM for many years.</span></p></blockquote><div>Regards</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Feb 12, 2019 at 11:28 AM Andy Townsend <<a href="mailto:ajt1047@gmail.com" target="_blank">ajt1047@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>At least one user claims already asked for permission to use this

<p>(I've not seen anything public from that source though, and of
course whether they gave permission doesn't address whether some
of the data has actually come from another source first, such as
the OS).</p>
