I have one data set which contains all federal states of Germany. The other dataset is about the population density in every km² in the EU.
My goal is now to join these two Datasets so I can answer different questions like 'how many km² with more than 5000 people are in federal state x?'
The first data set looks like this:
and the second like this:
I am very new to GIS programs, but from my intuition it sounds like a very basic need to combine different datasets in order to answer a question.
