I'm trying to delete duplicate nodes from a shapefile with QGIS, but after running the tool to delete it, nothing happens and shows the same errors.
I thought that maybe importing to postgis could be easier. What I want to do is:
Extract points from polygon (this is already done)
Delete the duplicate points
¿with st_equals?
To finish, reshape the points to polygons without the duplicate points.
Anyone know if this methodology would be ok? I can do the first and second steps, but don't know if number 3 is possible, or if there is a better alternative.
Any clue or suggestion?
