I have a vector layer with classified slopes in percentage (three classes). I vectorized that layer from a raster.
I want to eliminate all the small polygons from certain surface. I selected the polygons after calculating the area. I have this selection.
After selection I run the tool "Eliminate selected polygons" and I select to merge them with the neighbour with biggest area. The result is very bad. It eliminates some big polygons and keep some of the selected ones.
There is not options in the tool so I don't know what else to do or why it happens. All the polygons are valid. Some idea?
