[Qgis-user] Vector smoothing (polygons): topology/geometry problems

[celati Laurent]

Dear all,
I performed a raster segmentation from a Spot6 satellite image with OTB. I
polygonized/vectorized this raster segmentation in order to get a vector
file. To limit the pixelation of this cover, I was thinking of smoothing
the layer with the QGIS tool. This works, but the problem is that it
generates topology/geometry issues (overlap, holes, etc.). And I can't
afford to have invalid geometries. Could you share some advices? Guidances
in order to skip those problems? I've attached a screenshot of the smoothed
vector segmentation.
Thanks so much.
