I've been trying to clean up some vector data sets so that I can reproject them to WGS84 but I keep finding topological errors that fail the process. The one error I can't resolve involves a node on a polygon that shared by more than two (2) of that polygon's edges. For example:
Ideally, I would want to remove these types of topology errors so that I can reproject the shapefile but the QGIS 3 "Check Geometries" tool doesn't offer any suggestions on how to do it. I'm wondering what the best course of action is for these situations and if there is a tool/method that works best for these situations.
