Hi Welcome to OpenStreetMap.
Your addition looked OK, why delete it?
Regards Bernard

If American Starbucks Cafe is the name for the cafe then it would be good to tag the POI as such. Need any help just ask.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
I think you meant amenity=bicycle_rental instead of amenity=university so I've altered it for you.
Regards Bernard

Hello and Welcome to OpenStreetMap.
There is a "Bill's" cafe already mapped not far south from here. In converting this POI into a duplicate of Bill's cafe you have removed/overwritten the POI for "The Covent Garden Academy of Flowers". Do you mind having a look and making correction or reversion please.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
Was the reason for adding one node to mark where you live? If so unfortunately a single untagged node won't will not show. It would be much better to draw in a building and add the address. If I can help in any way please just ask.
Regards Bernard

Hi, is the path really formally named "Path"? Features added to the database should be verifiable to everyone.

Hello and Welcome to OpenStreetMap.
Thanks for adding a building to the live worldwide OSM database. A database which folk on lots of different projects including map making. Thus we all want the data to be consistent , correct and verifiable.
I made a few amendments to your building in order to keep to OSM best practice. I could find no reference to the name "Paradise" so wonder if it is a personal description.
Please have a look at how other similar features are drawn and tagged. It would be great to have more details on the building, use, address.
If I can help in any way please just ask.
Regards Bernard

Hello, you are quite right about the wiki and I was unaware of the advice not to use addr:street and addr:place together. I don't think it has any detrimental effect except to add unnecessary data.
I think I've now removed all tags addr:place=Swords that I added. If you see any I missed could you please amend them.
Thanks & Regards Bernard

Hello and Welcome to OpenStreetMap
I just looked at your recent additions to OSM because a section of highway was noted as duplication. I've removed the duplication's and added a service road so all is now OK. When you add or alter ways it's always best to amend what is already mapped thus a complete history of changes is kept. It looked like you may have inadvertently drawn the new duplication's atop of the existing ways.
Regards Bernard

Hi, yes all OK now park is removed.
It was might have only been a test but the changes were uploaded to the live worldwide database from which hundreds of maps are derived and updated. So not quite the place to make tests.
As I said though all is well. If there's anything I can help you with please just ask.
Regards Bernard

Hi, after no response I have reverted the changeset as it seems to be a fiction.
Regards Bernard

My apologies, the coastline incident was only indirectly connected to this changeset but was not your doing. That's been now sorted out. Sorry!

I did want and meant to comment on your new path addition though. Just to point out that it has not been connected/joined to the roads at either end but has been connected/joined to the landuse outlines. Thus it is way unconnected to the rest of the map and cannot be routed along. Also it crosses over three stream, it would be very helpful for folk to be aware of how the path crosses these barriers, ford bridge? Lastly is there a gate at the north end? Please see :- https://tinyurl.com/y95fc7cb

If I can help in any way please just ask.
Regards Bernard

Hello and Welcome to OpenStreetMap.
Unfortunately you've somehow inadvertently dragged a section the coastline out of shape. In order to put the coast back exactly as it was I reverted this changeset. I can't see what it was you were trying to correct so perhaps you could look again.
Regards Bernard

Hi SomeoneElse, the present tags were not from myself, a search shows the facility mapped to have actually been Clipstone Health Centre. If it's confirmed to not be now closed it ought to be tagged disused.
Regards Bernard

Hello and Welcome to OpenStreetMap.
I just wanted to let you know that Priory Country Park is mapped, I had sorted a lot of problems here earlier this year. It is this way Way: Priory Country Park (23604214) as can be seen here :- osm.org/go/eu6OElHc--?layers=N&way=23604214
So what you've actually done is repeatedly add a name on small areas of a whole park and that whole park was already mapped and named.
If you need any help with corrections please just ask.
Regards Bernard

Hi, I would think that by adding a fictitious lane you've made the situation even worse.
The number one rule is never map for the rendering of a map, and if mapped properly then a router fails it is a problem with the router not the mapping.
Unless I'm mistaken it is clear from Bing images that the section of highway=motorway_link you've added is not on the ground, further the A45 is not a motorway.
Regards Bernard

Hello, Way: Biddenham Farm (468715348) is not leisure=park as you've tagged it. Also the crop= tag is to indicate the type of crop wheat or potatoes for instance. The area may be part of Biddenham Farm but as you have indicated on other areas it is not it is not wholly the farm, It's better to indicate the whole farm in a relation thus avoiding unnecessary bloat to the OSM database.
Regards Bernard

Hello, Way: 542098857 doesn't look right. I doubt if there are any formal paths in this area as it is highway land and not a park. Anyway the paths you've drawn criss cross over each other without joining.
Regards Bernard

Lastly I think the sign you refer to in this changeset comment might be a temporary sign that is opened to sight occasionally for some reason I can't figure out.
Regards Bernard

You've also changed the main carriageway of the A45 trunk road from highway=trunk to highway=primary_link. This is obviously the main A45 carraigway so the alteration should be reverted.
Regards Bernard
