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.
Is there a prepared QGIS-tool to do this?
It is essential that layer A is preserved in its shape. Due to the different degree of generalization the poylgons' boundarys will differ as you can see in the picture.
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.
