Please don't assume iD is reliable. It's presets are often set to the developer's desires rather than those of OSM contributors.

Hi
All network rail stations exist. Please don't duplicate them.

Hi
node/6700043338
Is it a crossing of a bridge?

Hi
Please don't tag incorrectly to suit validation software. iD validation code is poor in many situations. All you have to do is not accept their inaccurate suggestions.

Hi
Do you know the building's purpose now?

Hello

It's not "an extreme area". It's contained within Britain.

You appear to be confusing me with OSM validation software developers.
Either:
1. Aim your ire of their poor programming skills at them.
2. Use software capable of providing you with the data you desire.

Multiple changesets for the same edit "makes it harder to track changes"

Thanks for noticing & letting me know about the landuse=residential area. Now fixed.

I believe it hypocritical for you complain about a way that "does not align with existing boundaries - such as walls, property boundaries" When you mapped two residential areas crossing a school:
https://nrenner.github.io/achavi/?changeset=81604078

You tagged the leisure area erroneously as 'pitch'
I corrected it to recreation_ground
You added an unnecessary, duplicating tag.
I amended that.

FYI you spelt Guide Post incorrectly.

Cheers

That's not a valid reason for removal.
Add access=private.

Hi
Why have you deleted valid driveways?

These two roads don't join. There a separating wall

Have you checked out JOSM editor with its Terracer plugin?

Hi
I changed the building to a train station. There should only be one entity per railway station. There will be multiple buildings/entrances for the Elizabeth line.
All the other EL building need to be tagged similarly.

No worries
Are you local? Do you know if they've broken ground at the site?
Will be worth adding a landuse=construction area if/when they do.

Hi
This is not a railway station yet.

Nice work on the Oldfield Park houses, btw.

Do you have a favourite 3d renderer? I found a couple to be cumbersome to use.

Hi
Unsure I'd describe Sainsbury's roof as flat: https://www.bathintime.co.uk/pub/media/catalog/product/t/m/tmp322359_1.jpg

Hi
Isn't South Devon Railway over by Totnes?

It's the route relation to which I'm referring. To which you added a 'v1' section, which I believe may make the route even more inaccurate.

In fact you're the creator & only editor of the relation.
https://osmlab.github.io/osm-deep-history/#/relation/11335129

As you know, route relations & highway tags are not synonymous.

"When editing OpenStreetMap, be cautious in what you change."

Hi
Have you ridden it? From the vague documentation it appears what's been constructed is only part of the original scheme & what's mapped.
For instance: is the bridge over the A48 in use?

Why have you added kinks into this accurately mapped road?
