It is a driveway, it has been tagged as highway=service which implies it is not a public highway. I will tag it more implicitly as as service=driveway, access=private.

Then the correct way is to tag it as access=private, not pretend that it doesn't exist.

Hi, welcome to OSM.
I am a little confused as to why you have deleted this service road, it appears on OS Opendata and is the only way to navigate to Cwmffrwd for delivery drivers so appears to be important information.

Please answer the question here, changeset discussion should be open and visible to all.
It is not acceptable to ask mappers to send changeset discussions to a non-osm email address.

Cheers Phil

In this case I would assume access=private

Thank you for your reply, however this needs access tags.

Hi, should these be tagged as parking_aisles and they should also have some sort of access tags?
Cheers Phil

Are you sure this isn't a track?

Cheers Phil

Hi, you seem to have added a network of roads here to which you have not added any access tags. There really should be some, clearly there are Health and Safety issues with routing through farmyards.
I assume you have inside knowledge of where deliveries are to be made, so you will be able to sensibly apply restrictions.

Thank you freebeer.

Reverted to commonly used name

Hi, thank you for this addition however please be careful and considerate of existing objects. In this case there is an existing track which you have crossed without connecting or tidying.

Hi, tertiary seems a bit of a high classification considering that it is linking to an unclassified. I would suggest this should also be unclassified.
Cheers Phil

Hi, thank you for your addition however it is a little incorrect.
Firstly the name tag should only be used on objects that have an actual name. They should not be used as a place to put a description.
The correct way to tag a barrier is barrier=*. Is this really a swing gate?
barrier=swing_gate
The usual barriers we use on rights of way are stile, kissing_gate and gate.

Hi, thank you for your edits. One small thing, the fact that these shops are SPARs and the opening hours you have included they are in fact convenience shops, we only use supermarket for larger shops that sell a wider range and have restricted Sunday hours.

Hi
The accepted practice for mapping schools and hospitals is to put the tags on the campus, rather than individual buildings.
In these cases both were already correctly mapped and you have created duplicate objects in the database.
Also please keep the name tag for actual names, short stay car park and long stay car park are descriptions not names.
Cheers Phil

They have been moved, not removed. No information has been removed.

Please keep to accepted names. The Oval is one of the most famous cricket grounds in the world. I cannot imagine that Test match Special will start calling Kia Oval anytime soon.

Hi, I think you have got this wrong. The Tigers play at Welford Road. The term stadium is never used. I suspect the site you are copying from has got some duff information from somewhere.
