How to Validate & Fix Geometry in QGIS 

SO simple and helpful thank you so much

Thanks for sharing your method. Excellent work!

this was very informative session.

Very helpful video! Glad I'm not the only one who spends a bit of time fixing geometry (other people's 😆). Couple of things to add. 1. The "Fix geometry" tool is also available under "modify features in place". So you don't have to create a new layer of fixed geometry every time. 2. There is also there the "check geometries" tool/plugin under the vector menu that you can use if you still find you are having problems with invalid geometry after you've run the two tools you ran here (lets you drill down and offers solutions at multiple resolutions). I find that ArcGIS and MapInfo are far less bothered by the quality of geometry than QGIS and PostGIS are. GEOS is a much higher standard clearly.

100 / 5.000 thank you so much, this helpful video🏅 just solved a topological problem🙄 I was struggling with

Thank you this helped😊
