#20384 new enhancement

Flag changed way segments going outside of the download area

Reported by: GerdP Owned by: team
Priority: normal Milestone:
Component: Core validator Version:
Keywords: template_report Cc:


What steps will reproduce the problem?

  1. Downlad an area that contains a small part of a landuse=residential" area which is crossed by a building
  2. Move a node of the residential area so that the building is inside the area
  3. Upload

What is the expected result?

A warning if the moved node changes a segment which ends outside of the download area, as this might produce more overlapping buildings in the area that was not downloaded.

What happens instead?

No such warning

Please provide any additional information below. Attach a screenshot if possible.

This is just an example because it happened to me recently. The same problem can happen when a
highway segment is moved.
I know this is difficult because we don't store the change of geometries so far. No idea if the validator is the right place to warn about this. Maybe it would be better to warn directly after the node move was done.

Another idea would be to add a node at the place where the - not yet moved - way segment crosses the download area.

I`d go with a warning right after the action but please in both direction, e.g. moving from outside to inside and moving from inside to outside.

comment:3 Changed 2 days ago by GerdP

The ticket is not about moving a node outside of the download area. It is about moving a node of a way where the next node is outside.

Replying to GerdP:

The ticket is not about moving a node outside of the download area. It is about moving a node of a way where the next node is outside.

Thanks. Still would prefer a warning with the action and not later from validator.

There are quite some actions which can lead to moving one or some nodes. How should e.g. deleting the last inside node be handled.
