I'm really surprised to see a phallic symbol scrawled on the map in the midst of an otherwise constructive looking changeset. Reverting on behalf of DWG.

dear Marek,

In this changeset and others you seem to be carrying out mass imports of buildings and then later deleting some of your edits.

Have the imports been discussed with the local mapper community and on the imports@ mailing list?

We at the Data Working Group are concerned that you are carrying out a mass edit of unknown quality without discussion with the affected community.

Can i ask what is the source of the street address and house number data? Is it from physical survey?

cheers

Following up from my comment on osm.org/changeset/37090506 - have you discussed these mechanical edits in advance with the wider community as advised in osm.wiki/Automated_Edits_code_of_conduct ?

dear nikospag,

This looks like a really large and significant mechanical edit. Has this change in tag been discussed on a mailing list or forum and a consensus reached with others mapping the road network in Greece?

There are guidelines for large-scale automated edits here: osm.wiki/Automated_Edits_code_of_conduct

In this changeset you've added a motorway which does not exist - osm.org/way/388891377

OpenStreetMap is an attempt to make an accurate map of the world. If a feature is not observable "on the ground" it should not be included in OSM. Many people increasing depend on the accuracy of the road network in OSM for routing purposes.

I'm reverting this change and may have to revert others you've made on behalf of the Data Working Group, as you make it difficult to tell which are bona fide edits and which are imaginary features.

Also, please observe good practise by adding meaningful descriptions to your changesets rather than the default "no comment"

dear cam98,

In this changeset you have added a lot of duplicate data for roads where they already exist on the map. Please don't do this. OpenStreetMap is like a wiki, where a collective effort produces better content. In adding duplicate data disconnected from the existing road network, these edits detract from the integrity of the whole.

dear cameronk1998,

In this changeset you've added a highway=proposed leading to nowhere that seems to have no basis in fact. OpenStreetMap is a shared attempt to create an accurate map of the world.

Could you please explain where this data is coming from?

Also, it is good practise to leave meaningful descriptions in the "comment" field of your changes so other mappers can follow along.

dear xproBeku,

Regarding your change to osm.org/node/3912708199 - If you don't know the name of a place, please don't write that down in OpenStreetmap, just leave the name tag blank.

I've now reverted this changeset on behalf of the Data Working Group - see osm.org/changeset/35763125

The changeset source claims that it derives from Bing data. However the tags on the nodes and ways do look as if this was automatically added from another source (e.g. an import or "mechanical edit") and there's significant duplicate data which does not take into account existing mapping. I wonder if the mapper can add any comment on this?

dear aitolos, Alex3271,

As of yesterday afternoon, when I saw Γιάννης 4 had started editing again, I did a mass revert of changes from that account and also Γιάννης 1; I didn't touch the third account that you mentioned as it has been inactive for a 5 months and, as you suggest, the hard work of unpicking has already been done by hand :/

I applied the longest block I can with my privileges and am consulting on how to extend the block, and I'll keep a close eye on the three accounts for a while longer.

The tools I used to do the mass revert are all available on github for anyone to use, though the interfaces are raw, so caveat editor. https://github.com/woodpeck/osm-revert-scripts

I hope this is enough for now?

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.
