Dear all, currently I am working on a project to analyse the bicylce infrastructure in Munich. Therefore I created different layers with the bicycle infrastructure and different buffer zones. Buffer zones include 200m 500m 1000m and 3000m The closer the zones to the bicycle infrastructure, the better. 200m (green) got grade 1 and 500 Meter grade 2 etc. So I would like to merge the currently four layers to one layer and include the information about the grades. I already used the tool union, but it didnt work. The tool merge, merged the polygons without including the information about the grades Hope that you get the struggle.
