Although you did not originally map these paths/footways, most really do not exist in any meaningfull way.
Especially 841759797.
These routes vary from year to year and even month to month and are mainly sheep tracks. It is misleading and even dangerous to suggest that someone lost in low cloud or whatever will be able to find a clearly defined path.

I have known and mapped this area over many years so have local knowledge.

Ah. I had not thought of looking on that commercial map site :-)

I don't like deleting other people's work without checking with them.

I have removed the emergency Phone fro the layby on node 1615630717,
osm.org/?mlat=51.83207&mlon=-1.82008#map=19/51.83207-1.82008&layers=D
after a video survey that showed no trace. Knowing the area a little, it does seem unlikely that it was ever there. It looks from the istiry as if you first mapped it.

What gave me pause was that the person who had added the footpath had joined it to the road on the other side of the bridge. Instead of just extending said road. That suggested that the road might not continue under the bridge.

Actually, I can see that you have merged from "here".

That is what it looked like, but with the two ways, one a footpath and the other road not quite coinciding, I though it best to leave it until someone local could fix things.

Have you merged the two ways? I haven't looked yet. Too late tonight...

Residents of Cornwall will be very surprised to find that there any any mountain ranges in the county!

Please correct or delete this: it is clearly wrong.

Why do you think that this is heath rather than grassland?
I have surveyed much of the area which I have known for a great many years. Such a large area contains a variety of vegetation, but it is mainly grassland.

There is definitely no shoulder on the A436 near the Frogmill which is where I first noticed this mistake.
And I am confident that this is true right up Fox Hill to the old Air Ballon roundabout. What was your source? You said survey, but that can't be right in those areas.

I will remove the tag on the parts that I know and have repeatedly surveyed, not least with video.

Perhaps you need to check the other parts that I have not surveyed.

I wondered about that, but was too lazy to check the wiki. Now fixed. Thanks. I see that I even mentioned it in the note :-( It was 5 years ago...

Whoops. You are right, I didn't scroll down the history far enough...

The discussion on the taggng list has moved on, and people have supported adding a depth tag even when it is only a guess. So perhaps I will leave it. I think 0.5m was my best guess when I mapped it.

Apologies...

I noticed that you had added a deep tag to the ford. I was prompted by the current discussion on the talk-gb list about hazardous fords.

I really wonder how you can assign a depth which is highly variable. Is this just a guess?

Just checked the history, and see that it was marked as residential many years ago. Looking at old imagery, there seem to be a few houses around the edge, but it most of it looks like industrial/commercial typical of an old quarry...

I have just received a email from SW Water which says:
"since last year have brought
Hawks Tor, an old disused quarry, into use as a new reservoir."

So surely your tag of residential can never have been right?

Presumably it needs updating at the very least. I wuld have said construction, but the email suggests that it is already a reservoir.

Maybe, just maybe, I might be able to survey later this year.

Yes, it looks a bit odd. I think that josm prompted for both tags.

I got the name from the sign on the wall seen in my video/gps.

I am not even sure that "place" is the right tag for a single entity, although perhaps place=farm might work. I guess that I will do that.

You seem to have added a higway tag to a node. Why?

Thanks for spotting that. I even had that plugin installed. I must say that even now, finding that option in the tool icons is not easy, and I need to remember to search for the right term (paste, say) to find shift-R. Josm is wonderful and can do almost anything, but when in a hurry, it is hard to find just what is needed for unfamiliar use cases.

OK, I have done a quick fix. By opening both josm and OSM view of the node, I could tranfer the tag information although it was still a bit tedious.

Yes. Yes. Josm complained as well.
I was in a hurry and it was a pain to transfer all the tags from the node onto the new way. Not that I think it's a very valid complaint by the editors. Maybe there is a simple way to move the information, but if so I have missed it.

When I have a bit more time, I will try and remember to clean up. Mind you the node is near the entrance, so I should probably tag the entrance as well, although I think there has been some tagging list discussion about entrance tags recently, so I hope that isn't going to be complicated. I might end up adding a small service road with a gate.

OK. I guess that you are a new mapper, and just getting used to the system. I use josm, so I can't help with iD which is what you seem to be using.

I was only drawn to look at your edits when you deleted a track that I had surveyed without giving any source beyond Bing. It may well be that that track has indeed gone, but it might still exist, but just not be so evident on the images.

Most of your edits seemed to be aimed at restricting access, or removing information, rather than refining it.

Most of ypur changes to private are valid, although I am not entirely sure about the Bromag estate. I know that is probably strictly correct, and that there is a gate and a security guard (or used to be).
But I suggest that access=destination might be better. There are many companies there who presumably need customers to visit, and access=private does suggest that there is no access.
access=destination is compatible with being private, and indeed implies that it is private.

You seem to be concentrating on local farms, so I suspect that you have local knowledge. If so that would be worth noting on source tags and on the changesets.

I think that many of your other access=private might well be better as access=destination for similar reasons for the Bromag Estate. Amazon now use our map for their deliveries (an often also contribute edits, although not always of the highest quality). If Amazon wanted to deliver to the Bromag estate or one of the local farms, they need access = distination I think.

Oh, and welcome to openstreetmap!
