Parcel boundaries have generally been undesirable in OSM in the past, mostly because to a lack of on-the-ground verifiability. The advice has always been: If there's a fence, map the fence, not the boundary. If there's no fence, then you don't know there's a boundary. If someone needs the boundaries they can use them them from the open data source themselves. That doesn't mean that people have not imported parcels of course. I think that in a discussion on talk-us, someone once claimed that it can be important to know for a rambler if they're on public or private land because they're more likely to get shot on private land. Hope this is not so much of a concern in the UK ;) Bye Frederik -- Frederik Ramm ## eMail frede...@remote.org ## N49°00'09" E008°23'33" ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

The main reason it is rare at the moment is probably that it is very difficult to deduce boundary lines from aerial images without very detailed local knowledge or surveys, of land that is private. And you do want to have them accurate and up to date. ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
Re: [Talk-GB] Property extents
I think in both France & Spain the cadastral information has been used largely for mapping buildings and not land-parcels. In places I know the French cadastral parcel data is difficult to interpret: overlapping parcels; individual buildings as multiple parcels; parcel boundaries not according to the location of the little yellow boundary markers on the ground etc. I presume some of these are artefacts of how the cadastre is maintained by each commune and subsequent digitisation. In some cases cadastral parcels do not seem to be consolidated, so it's impossible to actually derive real property boundaries without some on-the-ground knowledge. I'm pushed to think of lots of things I might do with parcel boundaries: accurate location of urban footpaths is one, nature reserve boundaries another (either directly or because NE data ceases to be encumbered). I don't know how much the parcels will accord with things like field boundaries in rural areas: I'll take a look at the LR Inspire data for S Derbyshire to get an idea.

Re: [Talk-GB] Mapping Mobility Stockport
+1 for wiki documentation. I am making efforts to bring the United Kingdom areas of the wiki up-to-date. I propose an "Accessibility in the United Kingdom" page, and I will encourage ODI Manchester to make updating it one of their project outcomes. A common OSM-wide page would be nice, but throws up issues of gaining worldwide consensus.
