I'm looking for a method to align the borders of two overlapping and already existing polygon layers. I'm aware of the node tool and its tolerance snapping option, but the area I'm working with is too large to do it manually.
I have two polygon layers. Layer 1 contains about 11,000 municipality features. Layer 2 contains 14 climatic zones (colored in picture 1).
As seen in picture 2 the outer border of the two layers do not fit. First of all I would like to manipulate the outer border of the climate zone layer (colored) so that it aligns with the outer border of the municipality features. Further I do not want the climate zone features to split the municipality features. One municipality shall be covered by only one climate zone.
At the very end I plan to intersect the two layers so that I have a list: Municipality ID to climate zone ID.
So far I only found a tool for ArcGIS, called Align to Shape.
Is something like this available for QGIS too?
