OK, no response so I've removed the duplicated sections maintaining relations.

Hi,
Welcome to OpenStreetMap.
I've placed the address details on the building outline and tagged the landuse=commercial. Made minor amendment to the address.
Is the building residential or offices please?
Regards Bernard.

Hi, Welcome to OpenStreetMap

I've removed Way: Durrell Road (784227611) and Way: 784227612 because you duplicated them. If a way needs amending please amend the existing way not add another.

Need any help please just ask.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
Sorry to inform you that I have removed Way: 784269301, Way: 784269302, Way: 784269303 and Way: 784269300 that you added. The reason is that they were all duplications of existing highways. Please therefore do not duplicate ways, if something needs amending please do this on the existing way.

I don't know exactly what you were trying to do but if you need help please just ask.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
Good of you to spot the typo.
I changed the name tag to a description tag as I'm sure that was not a formal name.
Regards Bernard

Hi,
That's great and quick as well, I guess you could be at home like me.
You missed a couple of double ones but I've fixed them as I checked. All OK now.
Regards Bernard.

Hi, It looks like you are inadvertently duplicating some nodes, please see here :-https://tinyurl.com/vsw92tr
I just wanted to let you know this. Can you amend the problems? If not I can, please just say.
Regards Bernard.

Hi, You added the tag highway=service to Way: Slough Trading Estate industrial railway (554725236). Thus making a duplicate highway. The tag of highway=unclassified was already on Way: Malton Avenue (26120212).

I've removed your highway=service tag.

Regards Bernard.

Hi, I've separated the field areas from joining at the center lines of the tracks. The fields do not extend to the highway center lines. Mapping this way makes it very difficult to spot mistakes under several lines.
Regards Bernard.

Hi Rick,
The iD editor you're using doesn't have all the possible variations of tags. No problem though that editor is adequate.
A couple of the paths you added actually look like they're used as cart-paths. There's a specific tag for this 'golf=cartpath', (I don't think it's in the iD editor), meaning golf carts should take these paths.

The other point was the landuse tag, thats used to show what the land is used for. This land is used as a golf course not for growing grass. So grass areas on a golf course are tagged as surface=grass.

As I said no great problems and they would be OK if just left, as we learn we work out better ways to tag things. Your mapping is actually pretty good.

Regards Bernard.

Hi, Welcome to OpenStreetMap.
Can I please point you to leisure=golf_course with regard to several golfing tags specially surface=grass rather than landuse=grass.
Also golf=cartpath regarding tagging of cartpaths.

Need any help please just ask.
Regards Bernard.

Hi, Welcome to OpenStreetMap.
How about adding the footpath then please?
Regards Bernard.

Hi, When you are adding a bridge you're actually duplicating the highway.
Way: 782818306 the bridge is on top of Way: 119312176 the road.
To add a bridge to an existing road please section up the road to accommodate the bridge then add bridge and layer tags to the existing highway section.

The bridge Way: 782512078 in changeset: 82364120 is also a duplicate highway. Also in other changesets Way: 782858734, Way: 782858733, Way: 782858732 and Way: 782858731 are duplicates. Could you please remedy these and take not for future bridge mapping.

I've corrected several duplication in previous changeset so they are OK.

Regards Bernard.

Hi, Yes that's correct. The particular existing way should be divided into sections and the relevant section of way be amended with suitable tags. You could tag for example
designation=public_footpath
foot=designated
highway=service
service=driveway
access=private, which means its a private driveway with access designated on foot, registered as a Public Right of Way.
Regards Bernard.

Hi,
You are placing some of these footpaths (which make up routes), on top of existing highways. This is duplication of highways, and disrupts proper routing.
If an existing highway has a section that belongs to a route you are making please section up the existing highway, not place a new highway on top of it. The section of existing way can be added to the route, with suitably adjusted tags.
I have amended several of the footpaths you've added to routes.
Regards Bernard.

Hi, I've removed your area Way: 780485186 because the parking space was drawn over several buildings.
Regards Bernard.

Hi, You've drawn the path (Way: 780564545) to cross over track (Way: 780564543) several times without joining. one section has the path and track on top of each other.
Do you think one highway should be removed? If there are two highways could you join them where they cross.
Regards Bernard.

Hi, In OSM negative attributes are usually implied by their absence. Thus intermittent=no, salt=no, tidal=no do not need to be added.

Regards Bernard.

Hi,
Welcome to OpenStreetMap.
I just wanted to point out that features added to OSM must have a physical presence on the ground and be verifiable to everyone. So the next passer-by can determine the same facts.
So I wonder if the path is actually formally named Barrie Pavement. If not the name should be removed.
I also question the area Way: CLC Entertainment ltd (781364721), what is it is it verifiable? As drawn and tagged there is not enough detail to be of use to OSM. It's not a good outline of the house nor tagged as such.
If you need any help please just ask. Regards Bernard.

Hi, Welcome to OpenStreetMap.
I think that this house is not formally named as 3 Middle Lane as it is the address. So I've removed the name tag.

Regards Bernard.
