The hedge was also self-intersecting, which is incorrect mapping.

Hi, You placed the hedge Way: 1182154351 on top of an existing hedge. I've removed the duplicate.

Hi, Welcome to OpenStreetMap.

Sorry to say you dragged the road out of alignment and changed a building to a landuse area, not to OSM best practice. Thus I've reverted the changeset.

Hi, Although I didn't add the cave entrances I do know that there are many caves in Croydon some of which can be entered. So these entrances could well be valid, thus I've reinstated them.

Please don't remove stuff just on your suspicion without investigation. I would suggest you contact mapper JDurn if you wish to question the cave entrances.

Regards Bernard.

Hi, I'm pretty sure that line is meant to represent the pedestrian area in the center of the garden. I've tagged it area=yes and highway=pedestrian which is the usual tagging for such areas.

Regards Bernard.

Amend building on top of building.

Hi, OSM would term Holly Close as a service road, driveway. There also looks like there's a gate across it.

Hi, Welcome to OpenStreetMap.

I think you wanted to join the new path between the road and the footpath. I've amended it to this end. You had the path joined to the area outline and the road.

Hi, Welcome to OpenStreetMap.

The untagged node has no meaning and thus is of no use to OSM, I've removed it. The Gherkin is mapped as a building here:- way/4959489

Hi, Welcome to OpenStreetMap.

Can you please give a reason for deleting these 12 highways?

Was it a mistake> Iif so I can revert the deletion for you.

Hi, Welcome to OpenStreetMap.

You inadvertently tagged two long boundary lines as highway=path, I've changed it back. I think this is the line you mistook as a path going through houses.
Regards Bernard.

More duplicated highways removed

Removed a very long bridge that duplicated an existing highway.
