Thanks.

This stuff looks real. You might like to click the icon that makes the houses have right angles. Most houses have squared off corners.

Have these buildings really been destroyed or is this an effort to attract Pokémon?

I will revert this edit.

Another imaginary park. I will revert this too.

Welcome to OSM

You seem to have added a park over the top of a house.

We welcome new editors adding new stuff but it must be real stuff, in the right place, correctly described. This isn't, so I will revert (undo) this edit.

Welcome to OSM

Thanks for the detail.

Your small park has a name that looks like a description. We only use names that can be verified, so names on name boards for example.

Welcome to OSM

From the aerial imagery your park is someone's garden.

New edits are welcome but they must be real, in the right place and correctly described. I'm not sure your edit quite meets this. Do you need help?

Welcome to OSM

You seem to have added Cairntows park over the top of the existing Cairntows Park. I will remove your extra park. Pokémon will still recognise the old park :-)

You can add an English name (name:en Dr Owen Park) and a Welsh name too (name:cw=Parc Dr Owen). Hope that makes sense, my Welsh is very sketchy.

Welcome to OSM

Looking at the park, I wonder if recreation ground might be better? The individual pitches can be mapped too if you want (leisure=pitch, sport=xxx) Does the park / rec have a name?

Welcome to OSM

Thanks for the extra details.

In OSM terms this is a leisure=playground, not a park. Hope that helps.

Putting imaginary stuff over the top of real stuff is vandalism.

I will revert this edit

You seem to have added a park over the top of an existing park. This is not a good idea.

I will revert (undo) this edit.

Welcome to OSM

You seem to have changes a children's playground into a park. A park is an area not a point ( a playground is often an area too).

We welcome edits from everyone, but they need to be real things, in the right place and correctly described.

Welcome to OSM

We draw parks as areas, not points. It is usual to draw roads in first as part of a new development. It you don't have a GPS (or a phone with a GPS in it) maybe a note would be best saying there is a new development so someone else can follow it up later.

Reverted

I have reverted this and your second edit. Both involved dragging points to new places. You can create new points and lines rather than drag stuff around.

Welcome to OSM

Is there really a tourist attraction slap bang in the middle of Charing Cross road?

Welcome to OSM
Thanks for the detail. It looks as though you added the postcode as the house number. Adding the postcode correctly makes is easier to find

Welcome to OSM

The restaurant looks rather close to the road. Shouldn't it be where the buildings are? Postcodes are very useful, but they need to be correctly formed, so they need a single space in the right place in the middle

HTH

Again you need to add tags to describe what you have added. In OSM a ginnel is highway=service + service=alley.
