In your second example, do you know that the oneway direction was wrong from local survey?
If not, the usual way is to get in touch with the previous editor via changeset comments and draw their attention to the impossible situation emerging. Maybe it was an error of them, but on the other hand, it might have been correct while another error caused the isolation.

I looked into the history of edits for that way where previously the oneway direction was accurately mapped with "oneway=-1" tag. Later the editor changed this tag to "oneway=yes" and forgot to change the way direction. I believe the editor made it by mistake, and also the changeset was huge to point to exact error location. So went ahead and fixed the way direction.

Sounds plausible. Thanks for your explanation.

... During this time, we have contributed a total of ~1600 changesets. Among these changesets we received seven comments from OSM community members requesting us to add missing gates or private information for newly added roads. We also received two additional comments from OSM community members for the roads added with reference to old satellite imagery in a coal mining area. We stopped our editing in the coal mining area promptly after receiving these comments. We responded to all the changeset comments within 24 hours, and any incorrect data was corrected immediately.

Hi Jothirnadh,

thanks for the summary.
Just to be clear - your above reply may be intended to lead to the conclusion, that only 7 required corrections out of those 1600 changesets may be a good ratio, but this would only be true - if all of those would have a confirmed local validation.
But this is something we should never assume - that a changeset without a local comment is a correct one (of course this is also true for all changes in OSM being done remotely).
Apart from that I see your process optimization points are a step into the right direction - but they should not be a one time effort.
Overall I think in this case commercial mapping puts a lot of additional effort on the shoulders of volunteers, while I am not yet convinced that the additional benefit outweighs the potential risks.

Hi tux67,

Thanks for your valuable comments. We are totally inclined to your points. With this post I wanted to emphasis the effort our team is putting in to improve the data in OSM. We made wrong edits in the past, but the team is learning quickly from our mistakes. We started to engage with the local community and learn from their suggestions. From the comments received in the past, we worked around and improved our mapping workflows as well.

We at Amazon are determined to contribute data back to OSM and our team is moving in the same foot steps. We are still new to editing in Germany, but from our limited interactions with local community we optimised our editing workflows to contribute back quality data. Please do continue to comment on our changesets if a wrong information is added. We will fix the issues within 24 hours and respond back to changesets.

Regards,
Jothirnadh

Following are few of the examples where Amazon editors have made obvious errors:

https://www.openstreetmap.org/changeset/70803893
The edits are still online.

It seems that these edits have been made to silence a quality management tool, which often leads to just hiding errors.
It takes a lot of time to investigate the edits of companies, which are done based on guessing/without local knowledge.
I strongly dislike such behaviour.

Hallo,

nun auch hier komische Eintragungen von Straßen:
https://www.openstreetmap.org/changeset/74114321
https://www.openstreetmap.org/changeset/74123631

Die Warnings werden wohl ignoriert...

Wie damit umgehen?

grundsätzlich würde ich bei verdächtigen Changesets kommentieren.

Wenn ein bezahlter Mapper so dumme Fehler macht (Straßen durch Gebäude), sollte man auch seine restlichen Beiträge sichten, kommentieren und Korrekturen binnen einer angemessenen Frist einfordern.

Da wurde einfach blind nach Maxar-Luftbildern abgezeichnet, ohne eine Lagekorrektur durchzuführen.

Oben in Beitrag #20 hatte ich genau so einen Fall. Im Changesetkommentar hat ein Vorgesetzter (?) zugesichert in Zukunft in diese Richtung zu reviewen. Naja...

Ich denke das gehört inzwischen zum reply - template:

Durchgangsstraßen über ein Firmengelände hinweg zu verbinden finde ich weiter in schwierig:

Aber ganz neu ist jetzt eine Bildquelle die scheinbar nicht allen zugänglich ist "Amazon Vivid Imagery":

Sagt das jemandem was?

P.S.: und noch so'n Querverbinder .. ist ein wenig Sisyfosmäßig inzwischen: https://www.openstreetmap.org/changeset/74798380

Noch ein interessanter Kommentar hier ..

Wenn die GPS Tracks den Fußweg des Zustellers mit enthalten, mag das einige interessante Edits erklären ..
