I have a polygon Shapefile, which I need to generalize. How can I generalize the poligons and ensure that there are no topological errors like "slivers".
I already tried:
- Vector -> Geometry Tools -> polygones to lines
- Vector -> Geometry Tools -> simplfy geometries ... here I can already see on the screen, that I am producing overlaps and gaps nevertheless now I try
- Vector -> Geometry Tools -> lines to polgones
and here the program show an error and crashes
