FWIW, in Merton (London Borough) I'm using the format "Merton FP 86". The numbering seems to be unique across the borough, not parish.

I've started an effort in that direction at https://osm.mathmos.net/prow/ref-formats/ . For each county in the list there's a regular expression for parsing the prow_ref tag, and a printf format for outputting a prow_ref tag from structured data. This is then what my PRoW tool uses internally. I'm in the process of adding the parish name/id lookup tables that I've collected to this page. There's a JSON feed with the data to make it easier for others to use it too. > On the other hand some counties do not use parish refs at all in hhe number, > though they do mention them in the full ref (e.g. FERNHURST 1254).

It seems they numbered their Rights of Way within each former district/borough. When this happens, in my tool I treat these areas as "parishes".

Hello Robert, I wasn't familiar with the situation in Dorset but MapThePaths uses the 'SE 4/22' scheme (actually it appears as 'SE 4 22') so if people want to use MTP as a source for prow_refs, then that would be the format to use. In terms of how I arrive at the references, I sourced the data from the rowmaps site and applied a script which looked for a particular field (I forget its name) in the rowmaps data. This is done consistently across all counties. I don't really mind too much what people use to be honest, obviously something like 'Studland FP 1' or similar would be more descriptive, but would require an extra step to look up the parish name. Maybe we should develop some sort of (crowd-sourced?) service which looks up parishes based on parish codes to allow easy contribution of descriptive prow_refs? On the other hand some counties do not use parish refs at all in hhe number, though they do mention them in the full ref (e.g. FERNHURST 1254). The Chichester district of West Sussex (not OGL, by the way - unfortunately from my POV as it's an area I'm interested in) appears to use a simple number for all PROW refs, ranging from about 1-3500. This is not consistent in a given parish, e.g. numbers between 1200-1299 appear to be spread between Fernhurst, Lynchmere and Milland parishes.

Currently in OSM we have about 394km of routes in Dorset using this style in the prow_ref tag, and another 98km using this style with a space instead of the slash.

Re: [Talk-GB] prow_ref format for Dorset Public Rights of Way
Hi Rob There is a very similar state in Lancashire, I can imagine the Lancashire officer providing a very similar response to that from Dorset. Dorset are saying that their definitive statement is listed by named parish, status and route number. I believe that as the public definitive reference is named parish, status and route number then that should be what is in OSM, using number references looks to me like an internal workaround for earlier computers and spreadsheets. Using named parish, status and route number also makes it easier to use on maps - eg Andy Townsends https://map.atownsend.org.uk/maps/map/map.html#zoom=13=53.6423=-2.5975 Regards and mapsafe Tony Shield TonyS999 On 16/04/2020 14:18, Robert Whittaker (OSM lists) wrote: I've recently been looking at increasing the coverage of my PRoW comparison tool https://osm.mathmos.net/prow/progress/ by adding new counties.
