A few quick notes, some of this has been said before:
- The license issue is complex, largely because there is no adequate
audit trail of metadata associated with the data. As Phil says many
definitive maps were compiled by parish councillors, but this would have
been in the 1940s and 1950s with maps which are now out-of-copyright. This
data would have been digitised (any-time from 1980s), but perhaps against
an OS map which is in copyright with or without revisions. Even a release
of data under OGL really needs clearance that OSGB see that none of their
data have been used.
- Definitive statements are more useful for us as they should describe
the path alignment in words. Most councils have not digitised their
definitive statements, let along released them under OGL. (Presumably this
is largely a workload issue: I have no idea if they would be amenable to
allowing digitisation to be crowd sourced).
- A few councils definitely have released their PRoW data under OGL, one
of them is Nottingham
<http://www.opendatanottingham.org.uk/dataset.aspx?id=74>, which I
believe sought the relevant dispensation from the OS. As an urban area
Nottingham was exempt from the initial PRoW collection of data and has only
been doing this under the CROW Act of 2000. This data is therefore much
more accurately digitised: the problem is that establishing the status of
some paths has been an arduous process.
- Other urban areas have significant problems in finding the actual
course of rights of way because areas have been built over. I think it was
Tony Wroblewski who told me once about these issues for the Littleover area
- The OS does not claim copyright in the PRoW data themselves. It may be
working with them on a clearer statement may help all concerned. This may
be something that OSM-UK's existence may make easier.
- The OS omits some PRoW data in hilly areas where the line of the
definitive map is clearly incorrect & following the line could put walkers
- Definitive lines in many areas have fallen into disuse and been
replaced by more attractive alternatives (typically a path round a field
edge rather than across the ploughed field. A good example surveyed on
several occasions for OSM is the bridleway
<http://www.openstreetmap.org/way/293561685>across Laxton Common to the
south of Wellow Wood. This is merely mapped with the designation & access
tags as, although it is marked there, is no trace on the ground.
- Minor deviations of a path from the definitive line are very common.
- Mapping infrastructure, barriers etc is extremely useful & often makes
route finding easier than with OS 1:25k maps.
- Mapping footpaths is fun, it really just provides a different set of
goals for constructing a country walk. So if you enjoy a country walk it
just requires a little bit more planning.
- Several of us create maps comparing OSM & data from rowmaps (me,
Robert Whittaker, Nick Whitlegg at least). Some of these are available
on-line. The ones I do are one-offs so dont get updated, but I currently
have fairly recent ones for South Central England (October) and North
