Self-intersection by JDK QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Repairs self-intersections, converts multipart to singlepart, computes area (Surface_Ha) and removes polygons from 0 to 0.25 ha.
About
Self-intersection by JDK repairs geometries (makeValid + buffer 0 to remove self-intersections), applies "Multipart to singleparts" to isolate non-conforming geometries, creates a Surface_Ha = $area / 10000 field, then removes features whose 0 <= Surface_Ha < 0.25 ha (upper bound excluded), producing a deleted-polygons layer. Graphical interface plus a Processing algorithm (Model designer / batch / qgis_process). Designed for geometric quality control (land, cadastre, agriculture, forestry, EUDR/RA).
