I have a shapefile with overlapping polygons. I need to clean these overlaps based on an attribute: in case of polygon overlap, the polygon with the lowest value of a given attribute needs to be clipped, while the polygon with the highest value of attribute remains the same. Any idea?
Ideally I'm searching for an automated solution with a plugin or a script. However my dataset is not really big (around 20 shp with about 50 features each and three different values of the attribute; no need to clear overlap between different shps), so manual work would also be ok, but which tool would be the most efficient in this case?
PS: this question could be a possible solution, but I don't have access to arcGIS.
