Hello all, I'm looking for some advice in relation to Geometry Error detection. We have a proprietary tool, which can validate geometries in line with OGC, which is flagging geometries as having holes outside of area. Indeed when I check the vertices I can see the issue, with the "Holes" sharing a node with the external geometry (at the edge, see image below). What I was hoping for was that we could show these same errors in QGIS.
[cid:image001.png@01D960A2.4CD1B300] I've used the following QGIS tools for validation of geometries with varying degrees of success, node directly flagging the issue detected. Check Geometries Plugin: Flags error in Geometry Type, but gives little by way of explination.. Topology Checker: Flags no errors Check Validity Flags no errors, with either QGIS or GEOS Is there a way to check geometries, a tool, python, and another application, which can validate geometries? Or a series of tools which strung together in Model Builder could flag the issues? Regards and thanks in advance, Richard. -- Richard McDonnell MSc GIS, FME Certified Professional FRM Data Management -- Oifig na nOibreacha Poibl?
