Jan 22, 2019 at 11:30 comment added oat I tried the suggestion from the link below to fix the "ring x not closed" error. However, the polygon regenerated from the boundary line of the lake is still ghost shape..... Post : gis.stackexchange.com/questions/170942/…
Jan 22, 2019 at 11:22 comment added oat I tried the Geometry validator plugin, and the error message for each of these 25 polygons is "ring 0 not closed"... seems the geometry of the polygons is problematic...

Jan 22, 2019 at 6:41 comment added Keagan Allan In ArcMap I would try running the "Repair Geometry" Tool. I am not 100% familiar with QGIS, but perhaps running the v.clean tool might help. I did a quick search and found this: gis.stackexchange.com/questions/167421/…
Jan 22, 2019 at 6:36 comment added oat Hi Keagan, I can edit other polygons on this vector layer of lakes, and also I can export the attributes of this layer as CSV file. So, I'm not sure if it is because the shape file is locked as read-only. Can you advise if there is such as setting for shape file, and how to unlock it in QGIS? Thank you.
Jan 22, 2019 at 6:28 comment added Keagan Allan Where is the data sitting? Is it still in a database? Can you export the data out to a local file and try edit that? Could it be that there is a read-only lock on the location the data is sitting?
