Deletion claims to succeed but doesn't

[Prateek]

Consider this intersection :
http://www.google.com/mapmaker?hl=en&fll=32.387636,77.253156&fr=0.000725,0.000858&mpp=2.017086&gw=39&ll=32.387645,77.25131&spn=0.010455,0.019827&t=h&z=16&iwloc=0_0&fid=4108548521624907051:6868241630016618986

Deleting it with "Feature does not exist" seems to succeed with a "The
feature has been published successfully" message. However, a find
reveals that the intersection still exists : I have "deleted" this
intersection several times already.

Hi, we have a limitation that any segment can be atmost 800mts long.
When you delete this intersection, the two segments on each side are joined together,
but this new segment is more than 800mts, so it is split up again,
and thus another intersection is created at the same place.

Can you clarify what you are trying to do?
If you want to redraw this road, then you should start with deleting the segments.

I see. This might be sound internally, but from a user's point of
view, based on what the UI shows him/her, it's still plain wrong: it
reports that the deletion was successful, but the user sees an
intersection at the same place as the deleted one (technically the old
intersection might have been deleted and a "new" one created, but how
should the user know?).

I was trying to align the road (currently drawn straight) with the
satellite imagery which shows a winding road on a mountain with
several bends. Since this was a unnecessary intersection, I was trying
to delete it.

So each time a segment is edited in a way that results in the final
length being more than 800m, a new intersection (or more than one) is
automatically created? In case of heavy editing of roads, this may
create unnecessary fragmentation.

Ideally, limits like this 800m should be purely internal, and should
not affect a user's experience.

Hi Prateek,
There has also been an Issue tracker report for the removal of such
legacy intersections. You might want to vote up for that and add your
thoughts: http://code.google.com/p/google-mapmaker/issues/detail?id=171
