Editor create duplicated ways as a second changeset #110

Closed tordans closed 2 years ago

tordans commented 2 years ago

We are mapping a lot with our berlin-edition of this editor (Link).

We are seeing an issue, where we have duplicated ways in two different changesets after editing.

What it looks like…

The duplicated ways show up as black line in a road segment that is mapped with parking lane information (colored line)

Example 2

This one was special, because a StreetComplete user edited both ways. I assume one via the in app AR Feature and one manually afterwards.

Cleanup process

We did a cleanup for Berlin and will look out for new ways to clean. Here is how I did that:

  1. Use this view to find duplicated ways http://osmose.openstreetmap.fr/de/map/#zoom=13&lat=52.4931&lon=13.42068&item=1230&level=1%2C2%2C3 (it also shows duplicated nodes, those can be ignored for this cleanup)
  2. Find the way id without the new tagging
  3. Use http://level0.osmz.ru/index.php > add the way w123 > change the name from "w123" to "-w123" in the editor, add a changeset comment "parking lanes; cleanup duplicated ways" and save.

A list of all removed duplicated ways is at https://osmcha.org/changesets/120548131?filters=%7B%22users%22%3A%5B%7B%22label%22%3A%22tordans%22%2C%22value%22%3A%22tordans%22%7D%5D%2C%22date__gte%22%3A%5B%7B%22label%22%3A%22%22%2C%22value%22%3A%22%22%7D%5D%2C%22comment%22%3A%5B%7B%22label%22%3A%22parking%20lanes%3B%20remove%22%2C%22value%22%3A%22parking%20lanes%3B%20remove%22%7D%5D%7D
