Outils de découpe QGIS et généalogie - cutting tools and genealogy

General
1

Hello,

I think the subject may have been discussed before but I’ve not found.

I am part of IGN France and we want to use the QGIS cutting tools.

But we need to have a notion of genealogy in the splitting. The largest object must retain our unique identifier, while the smallest object (polygon or line) must be considered as a creation, its unique identifier should be empty, and we need to have an attribute indicating its ancestor (the original object that was split).

Is there a way to set up QGIS cutting tools to take this into account? If not, we’re going to have to make a plugin with the same features as QGIS but that manages the genealogy…

Is that something that is of interest for QGIS user? Is it a common need?

I think it could be another way with one parent and two children? But it’s not our usual way of working for now..

Thanks.

Mélanie

Best to ask this question in one of the QGIS user channels - QGIS - OSGeo Discourse

The ones that come to mind:
For English - QGIS US - OSGeo Discourse

For French - QGIS-fr-user - OSGeo Discourse

Thanks Regina, agreed .

Can you delegate me some admin privileges for the QGIS category? I could move discussions to the right place and help manage the qgis community.
