I recommend you do the 'walkthrough' iD editor's help. Plus lookup shortcuts for 'split line'

Hi
You done it again here. Can you please revert this changeset & check any other of your edits.

Hi
OS maps are copyrighted & can not be used as a source for OSM.
if an existing way type requires amending the tags should be changed. An extra way should not be mapped on top.
If contiguous ways are of the same type with the same characteristics it should be one continuous way & not a few joined together.

Hi
What does 'ref:usrn' represent?

Larkhall is not the city. Have you considered editing only in your area where you'll have local knowledge?

Please do not delete valid data. amenity=pub/supermarket belong on the boundary way which encompasses all land owned by those companies.
Similar to schools.
i hope you haven't removed other examples elsewhere.

No worries. I wasn't waiting on it.
My list of OSM Things to do is getting longer each day.

Hi again.
I think you may need to have a look at this:
way/201298838

Hi
Welcome to OSM
Please note there are already subway station nodes. as railway=station. What you've mapped are building=train_stations.

What are these. They seems v. big for shelters.
way/787826600#map=18/51.11030/-1.87867

A name tag should be added to entities which have been assigned verifiable titles. These appear to be purely descriptive.

There are no public footpaths in Smallcombe wood

Which wall?

Hi
Farmland that has grass for feeding or crop is still farmland & would be better tagged as such.
Grass: "A tag for a smaller areas of mown and managed grass for example in the middle of a roundabout,"

landuse=grass

Hi
Please don't add highway=footway to platforms as their default purpose is to have people walk on them.

Hi
What do the public_transport=platform tags represent of the two ways?

Private Land doesn't exempt entities from being mapped.

Hi Andy
I presume this edubase ref is meant for the school entity. Could you check it's the correct one please.

https://osmlab.github.io/osm-deep-history/#/way/129554842

Hi
It wasn't tagged as a public footpath. It had access=private on the section by the houses. There's definitely a worn, defined path in the woods. These ways shouldn't have been deleted.

Hi
Do you know what the local_ref tag which you amended at this station refers to?

Please don't remove railway=platform tags.

Hi
I think your edit broke The Cotswold Way relation in a couple places. Could you take a look at it please (The blue markers in the middle)

Do you know if the route is accurate, as signed on the ground? Google show it heading along the bridleway you created.
