My view on the licensing question: Very many geographic datasets published by UK public bodies contain data derived from MasterMap or other OS products used under the Public Sector Mapping Agreement. If the public body has published the data under the Open Government Licence, and includes OS rights in the attribution statement, then it's reasonable to assume they have obtained the necessary permission through OS's "Presumption to Publish" process. Users don't have to confirm that with OS themselves.
For more discussion on this point see the recent High Court judgment in 77m Ltd vs Ordnance Survey, from paragraph 255: https://www.bailii.org/ew/cases/EWHC/Ch/2019/3007.html Owen On Sat, 16 Nov 2019 at 17:56, SK53 <sk53....@gmail.com> wrote: A few things: > > - A number of SSSI's are mapped > > <https://taginfo.openstreetmap.org.uk/search?q=site_of_special_scientific_interest#values> > as many are co-incident with various types of Nature Reserves, although > sometimes there are minor differences in boundaries.
