This changeset contains another fictious and damaging contribution to the map - osm.org/way/378864130

Mappers in Greece have attempted to get in contact and to reach out in an attempt to help, but it does not appear, lookin gat your recent edits, that you wish to help create an accurate map of the world.

There are too many changes to examine each on its merits and your edits are causing upset to others in the community in Greece. We at the Data Working Group plan to go ahead with a mass revert of your contributions. Please take this up with data@osmfoundation.org if it is a genuine problem for you.

dear Alex3271, thank you for bringing all this to the attention of the DWG. We are considering a mass revert of the changes under discussion but I want to take a little time to assess their impact properly first, which will involve spending a bit of time with achavi - https://nrenner.github.io/achavi/

I hope and aim to be able to wrap this up by the end of the weekend. Please bear in mind that, as with everyone in OSM, the DWG are volunteers too :)

I am going ahead and reverting this, along with the other "no comment" changesets left during the previous five days, on behalf of the Data Working Group.

If you have problems with or questions about this decision please contact data@osmfoundation.org

dear Γιάννης 4, Please excuse my writing in English.

You have added some changes here which look as if they don't correspond to features in the real world - for example this large roundabout at an intersection here: osm.org/way/377981128

And this impossible-looking motorway intersection here osm.org/way/332937638

Is any of this data from survey or observation? I should let you know that your recent edits have been flagged up to us at the Data Working Group as potential map vandalism; I may have to go ahead and revert the changes; it would be great to hear an explanation from you.

dear Guy, I write on behalf of the OSM Data Working Group. This discussion has been sent our way due to concern over data derived from the Google API (via doogal.co.uk) potentially being added to OpenStreetMap. As Richard points out above, this data can't be used within OSM. See osm.wiki/FAQ#Why_don.27t_you_just_use_Google_Maps.2Fwhoever_for_your_data.3F for more detail on this topic.

There are other, open-licensed sources of UK postcode data that you can use, for example http://uk-postcodes.com/ which provides data with the Open Government License (formerly the Ordnance Survey Open Data License).

Please don't use the Google Geocoder or related services when editing OpenStreetMap.

Please excuse my writing in English, and thanks for your recent efforts to contribute to OpenStreetmap..

There are a lot of changes here, and many of them seem to be duplicating data that is already on the map. Here is a simple example of a way that you've added that is already included in OpenStreetMap. osm.org/way/367776389

May I suggest that you upload fewer changes at a time, also to leave some descriptive comments when you save changes to the map, so that other mappers can follow your work.

By adding duplicate data you dilute the quality and usability of the map, which is why your changes have been flagged up to the Data Working Group as candidates for reversion.

reverted in changeset 32593527, could be pending further discussion by the mapper.

- on behalf of the Data Working Group

Please excuse my writing in English. What is the source of this data? Is it from personal survey, or from some unknown source?

Please can you use descriptive comments in your changesets, so others can tell what is going on, and also attribute the data sources that you are using while contributing to OSM?

Otherwise, as this is duplicate data from unknown sources, we at the Data Working Group may have to roll back (revert) your contributions to the map.

Could you please use comments to describe your edits so that others can get an overview of what has changed?

Forgive me for writing in English. This changeset was flagged up as problematic to the Data Working Group. It would be really good to hear more about the reasons behind the changes.

Understood, I am assuming good faith here, only suggesting that you slow down while the issue is causing some contention between mappers...

Have the names been replaced or restored since?

Right, in the history of osm.wiki/WikiProject_Greece I see a lot of your own edits recently, but I don't have a sense that this wiki page reflects community agreement yet.

hi JayCBR,

There are a lot of changes listed in this changeset. It would be clearer for others if you could upload in smaller changesets.

In the edits here, there's been a particular query about the National Road 8 classification - osm.org/way/31640151/history#map=15/37.9397/22.8377 - you changed the ref: to EO104 in this changeset. What is the source of the change or the reason for the re-classification?

Thanks for your response JayCBR, the offer to revert in a few places is generous and may still be necessary. I hope that Amaroussi's effort at a consolidating wiki page proves useful to you. Good luck, both of you!

dear JayCBR,

In this changeset and others you have made some quite sweeping changes to the OSM database. It would be helpful to others if you'd leave a comment when you create a changeset; also consider uploading changes in smaller batches.

Please consult others in the OSM community before making sweeping changes. You're not slowing down to make your case to other mappers, and unfortunately your recent changesets have now been flagged up to the Data Working Group as potential vandalism. I want to assume good faith, but you need to spend time dealing with the community and explaining your edits, or risk being reverted. Again, clearly descriptive comments with large changesets would help *a lot*.

Reverted, along with the other changeset at 29193535, on behalf of the DWG.

Following the import guidelines - osm.wiki/Import/Guidelines - it is important to discuss and document a signficant import before adding to OSM. This should help to ensure a more coherent data model as well as a harmonious community.

As it stands, this and the other boat access bulk import at osm.org/changeset/29193535 haven't been through the process suggested by the guidelines and have been flagged up as problematic to the DWG, so we will have to go ahead and revert these changes. Wishing you luck in the discussion of the import.

hello Parcanman,

This looks like a mass import of data from a third party source that hasn't been discussed with the wider OSM community.

You may not be aware there are import guidelines osm.wiki/Import/Guidelines including an imports@ discussion list, where mass additions to OSM of this kind should be discussed; there you should be able to get help with most appropriate tagging for the data and linking it to objects already in OSM.

osm.wiki/Imports

Another mapper has been in touch with the Data Working Group to complain about this undiscussed import and request that we revert it, along with osm.org/changeset/29192498

It would be good to hear your opinion, as it stands the DWG is likely to go ahead and revert these undiscussed imports...

OpenStreetMap is an attempt to create an accurate map of the world. Please do not add personal / test data to OSM.
