I am trying to clean our cadastral polygons, eliminating gaps, overlaps, missing vertices at intersections, etc. I have tried the Snapper, GeometryValidator and AreaGapAndOverlapCleaner transformers but some of the polygons are regenerated with additional vertices due to the adjoining polygons missing vertices at intersections, where I would have expected them to be broken and a vertex added. I need the recommended transformers, with the correct parameters, that can clean up the topology of our cadastral polygons. I also wish to retain the data of all the attribute fields, if rebuilding the polygons is necessary.
The attachment shows the topological errors that I am trying to clean.
