Hello,
I'm writing this here because although it's not the same issue as
"remote detection of tracktype" at all it is another example of how
well-meaning remote edits can cause problems:
With a DWG hat we occasionally have "fantasy" mappers reported to us,
and need to revert everything they've added. Usually it's pretty
obvious to tell that needs to be reverted, and usually the reverts apply
cleanly without any post-revert tidying needed, since "fantasy
additions" usually just need to be removed and are unlikely to be edited
by other mappers, since they (obviously) don't exist.
Occasionally though we find that someone has "corrected" some of the
data - a notable example in the past included correcting the tags on a
"bank ATM" that someone had added as an API test in the middle of the
Sahara Desert. "Fixing tags" on restaurants in the middle of the
Atlantic Ocean floor has happened too.
Just now a previously-blocked "fantasy mapper" has returned to Ireland
and added an "unlikely" shopping centre and some made some "unexpected"
road class changes. Unfortunately another mapper has "tidied up" the
shopping centre, suggesting to me that they think it's a legitimate
feature. The tidier-upper claimed to use Esri, Maxar and Bing imagery
(which don't show the shops, of course), but just in case it really does
exist, I've asked the tidier-upper and on talk-ie before I delete them.
However, assuming it really is an imaginary shopping centre all the
tidier-upper will have achieved is to waste both their time and my time,
and have OSM maps have invalid data on them for a bit longer.
Therefore, if you're going to edit things you don't have personal
on-the-ground knowledge of:
1) Please do check that the thing that you are "correcting" is
plausible. A bank ATM in the middle of the Sahara Desert is not.
2) Do check if the thing, if at all unlikely, hasn't been added by a
user who has had previous fantasy mapping reverted or who's changeset
comments suggest that their edits might not entirely align with
reality. In the case of the "shopping centre adder", they've been given
a 0-hour "message that they have to read before editing again" and their
previous changesets show the comment "This changeset has been reverted
fully or in part by changeset XYZ where the changeset comment is: ABC"
Best Regards,
Andy (from the DWG)
