I'd like to combine two layers of different administrative areas. One layer is more accurate (layer A) than the other one (layer B) in terms of generalization. So is there a prepared QGIS-tool to do this?
My first attempt was to substract layer A from B. By that it is ensured that at least the shape from the features of A are preservingly included. But close to the meeting edges from those two layers there happen to be fragments of the replaced features. I'd like those fragments not to be merged with the replaced ones, but merged with features they didn't originally belong to. So as you can see, my approach is probably not the best.
I hope you understood what I wrote, because I'm not really familiar with GIS (and English). Thank you
