Hi, this and your other changesets of this nature appears to be mechanical edits.

Where did you discuss them? What mitigation have you taken to check other objects that depend on the direction of the way?

Why do you see this documented tagging as a problem that needs fixintg?

Cheers Phil

Thank you, useful to know so that I can avoid it in future.

Hi, please could you explain what the purpose of this, and your other, changeset was?
If there was an issue that needed fixing I would have preferred that you comment on my changes rather than jump in with both feet and fix what is a work in progress.
Cheers Phil

Thank you. I do add lots of stuff to OSM but am concerned that the project should stick to its principles and map from allowable sources. I do question the value of bus routes in OSM. They frequently get added and rapidly become stale. Also knowing that there is a route there is not much help without timetable information.
Public transport information in the UK is far better served by Traveline which maintain timetables and routes nationally and use OSM. They do contribute to OSM. We do have permission to use their data in OSM, you need to ask them for an ftp account.

Hi, this edit has gone a little wrong. You have added this service road through an existing building and commercial area. Please slow down and take your time editing, mapping is not a race. Often when adding new objects we need to tweak and improve existing objects.
Cheers Phil

Hi, this and many of your other bus routes in this area appear to be in breach of copyright.
It is important to maintain the openess of OSM and only use allowable sources which we have permission to use.
In this case the map is based on OS and is crown copyright.
Please revert this and all copyright infringing changesets.
Cheers Phil

Hi, welcome to OSM. Thank you for your edits however this one went a little wrong as the Cambrian is not in a tunnel here. I have fixed this.
Cheers Phil

Hi, this edit has gone a little wrong.
You have drawn a new driveway connecting to Rhos Y Madoc Road, however there was already a track (osm.org/way/479144418). Your edit should have merged the two as you have now created a second junction which does not exist.
Please slow down and take more care, look at the existing objects and maybe improve them also. Mapping should not be a race against the clock.
Cheers Phil

Hi, welcome to OSM.
Thank you for your edit and I am inclined to agree with you. However rather than delete the object it would be better to restore the tags from an earlier version and make it a school again.
I will fix this later.
Cheers Phil

I suspect it should be wikipedia, rather than website.
Cheers Phil

Hi, thank you for your edit however the garage was already mapped but with the old name. I have removed your duplicate and updated the original object.
Cheers Phil

Hi, smoothness = bad is very misleading, it is is used to describe a rough track. It is not really appropriate to describe either The Burway or The Portway using these tags as they a both asphelt roads that are accessible to normal road vehicles.
Also please do not add unnecessary tags, foot=yes, oneway=no along with access=yes. They add clutter and make it hard for other mappers to spot the important tags.
Cheers Phil

Hi, in OSM a way represents a physically separated piece of road. Here you have mapped turn lanes (with no separation) as ways. This is entirely wrong.
If you want to map turn lanes please use lane tagging.
Cheers Phil

Please keep your changeset to sensible areas, the comment you have made implies this should have been at least two changesets.
Cheers Phil

Hi, welcome to OSM. Please could you explain what this is intended to be?

Hi, welcome to OSM. Thank you for your edit however it has gone a little wrong.

Firstly when 'fixing' things please try not to delete and start again, it is far better to try to improve things but the biggest problem is that you have deleted a section of public road and redrawn it a long private roads through a farmyard. This is a very big error that needs to be fixed.
When mapping please do not rely on aerial imagery, especially in areas that you are not familiar with but use other sources such as public gps traces, OS Opendata.

Please remember that OSM is now 12 years old and such a wild inaccuracy is unlikely to have not been spotted.

Please also make you changeset comments human readable, a failing of hot is that they encourage gobbledygook that local mappers are unable to understand. Cyclic redundancy check for example?

I hope you will take these comments as a means to improve your mapping, but the first rule should always be map where you know and hence learn to interpret the sources.

Cheers Phil

Hi, welcome to OSM. The correct term for a play park is a playground. I have corrected the tagging as this is not a park.
Cheers Phil

Hi, this edit has gone a little wrong, there is no "2nd" connection to Shaw Lane (Trunk). This driveway should end at Shaw Lane (Residential).
Cheers Phil

Hi, I think you had this right first time. This is a driveway into a school which is obviously private, you should not expect public access here.
Cheers Phil
