as often the input quality of datasets is “not great”, it would be great 😀 to have something like a Check Geometry Node. Shapely provides something like this with shapely.is_valid_reason — Shapely 2.1.2 documentation and shapely.make_valid — Shapely 2.1.2 documentation
The node would allow the user to select the geospatial column to validated. In addition the user would be able to select if the shapes should be only checked for validity or if it should make all shapes valid.
If checking is selected the node would add a new column Valid with true/false as value.
If make valid is selected the user would be able to choose between replacing the original column or adding a new column.
