<p class="MsoNormal">Dear all, </p>
<p class="MsoNormal">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. </p>
