Polygonize (Raster to Vector). The borders of the polygons of course <br>
exactly follow the borders of the raster cell. In ArcPro, there was an <br>
option to create simplified polygons when polygonizing raster data. I <br>
tried to find a similar tool in QGIS or a way to simplify the polygons <br>
resulting from Polygonize, but did not find any solution that does not <br>
produce gaps or overlaps.<br>
<br>
Any suggestions are greatly appreciated, thanks!<br>
