Hi, welcome to OSM.
Sidewalks should only be drawn as separate ways if there is a physical separation. Then you need to make sure you make all connections, otherwise you will cause some very silly routing, The normal way to add sidewalks is to tag the road, sidewalk=both|left|right.

Hi, these are definitley areas of grass, certainly not parks so I have reverted this change.

Thank you for the explanation, it is fine,
Keep up the good work.

Hi, welcome to OSM.
Deleting paths because they are private is the wrong way to go about things, they are a feature on the ground and should stay in OSM. If they are private they should be tagged access/foot/bicycle=private.
OS maps are copyright and should not be used even to check something. Use the evidence you see on the ground.
How did you clarify access rights?
I hope you understand my concerns, but in terms of copyright we need to be squeaky clean.

Hi, this looks a very odd edit. Please can you explain?

Hi, I think this has gone a little wrong. What you have tagged as a private park is actually a garden. I have removed this error

That looks good, thank you

Hi, we do not map airbnbs in osm. I am reverting this edit. It is also unlikely to be in the middle of the road.

Hi, the correct way to map aavement which is attached to a road is by the tag sidewalk=left|right|both. They should not be mapped as separate ways unless there is a physical separation. Mapping as you are doing breaks rendering and spoils OSM for its users. Highway=pedestrian is intended to be used for pedestrian streets in town centres, not to give area to footpaths. Your edits in this area seem to be crayoning for the renderer.

Hi, welcome to OSM. I think this edit has gone a little wrong, you seem to have added a caravan site which should be tagged as tourism=caravan_site but you have probably pressed a wrong key and tagged it as a park. Please can you correct it?

Hi, the YHA in Earls Court is already mapped. I am therefor removing your duplication.
I also doubt that Casa de Ania is in the middle of the road.

Hi, welcome to OSM. Thank you for your contribution however there are a couple of issues.
It is still a building, area=yes on its own does nothing and is not needed on a building.
In order to render it needs a tag, rather than remove the shop tag it should be changed to shop=charity, if you want to clarify that further you can add an extra tag such as charity=furniture.
Just ask if you need any help doing that.
Cheers Phil

Hi, welcome to OSM. Thank you for your addition however it looks like it should be a recreation ground rather than a park.

Thank you for making the corrections, however your changeset comment is still hashtaged, hashtags belong on twitter, not in OSM, thanks.

Hi, welcome to OSM. Thank you for your contribution however the tagging appears to have gone a little wrong, it is easy for newcomers to make these mistakes.
You have said you have mapped a wood, and I can see a wood exists however you have mistakenly tagged it as a park. Would you correct that? Also the name looks odd too, according to OS Opendata the wood is called Lower Helsdale Wood.

The mapping of these also feels wrong. They seem to be existing car parks, so the tag should (if allowed, although there is a pretty big notice saying it must not be copied) be added a tags to the existing objects. However the site uses google maps which makes the data incompatible with OSM even if permission is given by the website.
Unless you have actually visited these places and confirmed that overnight parking is allowed I feel that this should be reverted.

Hi, mae hyn yn ddefnydd rhyfedd iawn o'r briffordd = preswyl. Fel arfer, ffyrdd sy'n arwain at ffermydd yn cael eu mapio fel naill ai annosbarthedig neu wasanaeth yn dibynnu ar amodau'r mynediad.
Hefyd dylai'r sylwadau changeset fod mewn iaith glir fel y gall mappers eraill yn deall, yna yn hytrach na twitteresque gobbledy gook.

Hi, this is a very odd use of highway=residential. Roads leading to farms are normally mapped as either unclassified or service depending on access conditions.
Also changeset comments should be in plain language so other mappers can understand then rather than twitteresque gobbledy gook.

Hi, I know the tagging here was inconsistent. But this section was probably right.
Kingsland Bridge and the associated roads are privately owned and not PROW hence access=permissive was correct.

Hi, should footway way/485430915 not connect to Bynner Street, rather than the Prince of Wales car park, it should also connect to the service road (probably needs parking_aisle too). I did spot some sort of path there yesterday after a couple of Threads to get a chinese. Will have to explore, but do you know its legal status? It looks a useful cut through.
Also what is Prospet House, it looks large and should probably have some sort of operator tag.

No response so reverting
