If I am not mistaken, the old tagging was correct. tourism=camp_pitch is used for spaces, while tourism=caravan_site is used for the grounds

Thank you for adding. Make sure to square the buildings by pressing Q while they are selected. Also, make sure that you have correctly added all corners (there are some incorrect 45 degree exterior angles on a few buildings).

Also, based on the quality of imagery available, you probably could have added more detail to building outlines. It is not necessarily wrong to map them as you have, but it is always better to capture the shape more accurately.

One of your outlines took a detour onto an address node: way/1219860718. You can fix by extracting the point with E. You can toggle off features you don't want to see under Map Features > Map Data. Toggling the points off will prevent you from snapping to the address.

One thing you can do to improve accuracy further is "conflate" the addresses and buildings by selecting the building and corresponding address node and pressing C. This will delete the node and move the address information to the building.

Individual caravan spots like way/1039225898 should be tagged with tourism=camp_pitch instead

I see some unit ranges were converted into dates, like node/4059093781

Maybe it is an issue when preprocessing in Excel?

Make sure to cut out residential areas from golf courses

Please use the proper name for the LDS church:

Why have you changed the denomination to an obviously wrong value?

Members of the multipolygon are touching each other, which is invalid. way/492440869 and way/492440734.

Doesn't make sense to have a building way as an outer way for a building multipolygon. The issue is that types are being mixed up (a single relation has features of both type=building and type=multipolygon. I will fix.

Coming back to this (as I see the name is still there) I see this name is definitely wrong: way/710765977

Oops. Darn Brits. Thank you for catching

Misspelled Wikipedia tag "Hammet"

The inner school probably never should have been tagged to begin with, but in any case it no longer exists so I deleted it.

Don't make changes just to get rid of validator warnings.

Features are marked private with access=private, not private=yes

Inner polygons of the water area don't actually need any tags. They were tagged that way by inexperienced mappers such as myself in the past.

You would probably not describe a wetland as a forest no matter how many trees it had, so I would not tag it as a forest.

Please do not tag common areas as parks unless they are actual parks. You can tag as landuse=grass instead. And not everything needs a name. You would never say to someone "There is a park surrounding this walkway called 'Parkway Pedestrian Access'." so you should not tag it that way either.

The parking lot is not named "RV Parking". That is a description.

This is a private residence, not a hotel
