Note that the "Ldesignation" lengths are only approximate (and will normally be an over-estimate) as the tool does not check precise parishes for ways with a designation tag but no prow_ref tag. Consequently, it includes any OSM ways of this type that fall within the rectangular boundaing box of each parish, rather than just those that are contained within the parish boundaries.
This tool takes information about Public Rights of Way from four sources and flags up possible errors / omissions / things to check. Currently only a handful of counties are available, but hopefully more will be added in due course. The data sources are:
I've got scripts to do the extraction from first two sources set up. I can do the third behind the scenes, and there is an experimental interface set up for the fourth. Get in touch if you would like to try this out.
With the data the tool can then flag up issues such as:
The tool is currently under development, so various key bits of functionality are not implemented yet. For details see the Known Issues and To Do List.
However, please do not use the PRoW GIS data alone to map routes in OSM. The data may not be completely accurate or well-aligned, and it is important that we capture the physical presence and accessibility of routes on the ground too. Simply copying the Council's GIS data into OSM adds very little to the map. Correctly mapping a path with the condition of the surface, adjacent hedges, gates and stiles is much more useful. See also my advice for routes not following the definitive line.
I intend to add more areas as and when I have time to do so. The main constraints though are having access to the data and it being available for re-use under a suitable licence for use in OpenStreetMap. The basic requirements are:
For my own use (and for anyone else who's interested) I've written a set of import instructions outlining the process of adding a new county to the tool.
It is also useful if the authority makes available its Definitive Statements, List of Streets and a list of Traffic Regulation Orders affecting Public Rights of Way. See my Council PRoW Open Data page for an incomplete list of what is available from each authority.
