Is there a way to keep history on all segment while "split 3 part of highway" in JOSM ??

Posted by Akrimullah on 2 July 2020 in English (English)

So in JOSM, if I wanna split a way into 3 part, it asks which one of the segment that I want to reuse the history. instead of one, i really need all segment to keep its history so the community still could track the previous mapper edits. I think it’s not fair if the rest of the segment become our data because we only split it not add the new one. Here the illustration which i refer to. Untitled

Not possible: The history is the record of changes to an object. When you split a way you are removing some of the points on that way and putting them into a newly created object. All JOSM is asking is which way object from the split should retain the original object ID, the other(s) will get new object IDs. In any case they all can’t have the same ID and history.

Well, maybe a revision would be nice. from forum discussion

To get a correct history of a way, it’s probably better to get the history of the nodes.

And check who created those nodes, and who altered it.

The first nodes should typically relate to the first way creation. But in many cases, it can be crude sketch from aerial imagery, or something imported.

So if you see a majority of nodes was added or refined later, it’s clear that person is responsible for the current geometry.

Though at the moment, this is pretty hard to do. It would require a bit of tooling to get insight into who made the geometry as it is.
