[Talk-GB] prow_ref

[Dudley Ibbett]

As suggested I've downloaded the kml file for Derbyshire and found a plugin to view it in JOSM.  The paths have a code DY|AV3|3/1 for example.  It would seem County Council=Derbyshire (DY), Borough Council= Amber Valley (AV).  The number 3 appears to relate to the parish.  (i.e. it changes as you change parish boundary.  The last two numbers related to the path.  The first one appears to correspond to the numbers I have on my map (30-40 in each parish) but it also appears they segment the path with the last number.  I don't mind splitting paths (ways) to the first number but it would be a lot of work to the last level.  i.e. where there are currently 30-40 ways it could turn into 3-4 times this.

I guess the only debate is whether to use the whole number or drop the DY|AV3| given that in theory these area already mapped.  i.e. county, borough, parish, although the latter is a namer rather than a number.  Presumably there is no harm in using the whole and having a degree of data redundancy.

So,  should it be DY|AV3|3 or 3?

It is useful data as it has highlighted a path that I didn't know existed near to me so I will need to go and explore.  I'm not sure I would use it for actually mapping as it doesn't seem to correspond to what is on the ground in some cases having had a quick look around the parish.  I presume it hasn't been imported for this reason.  Has anyone developed any tools to highlight missing paths in OSM using this data?

Many Thanks

Dudley

The conclusion seemed to be to add the reference in the same format as used by the Local Authority. Some include the parish name, some also include FP for "footpath" etc. As your data is from a Parish level it's unclear whether the Local Authority will include the parish name before any numbers - are the numbers small (1, 2, 3) or up in the hundreds?


Where are you looking (geographically)?
