My GIS skills got a little rusty and I am new in using QGIS (I have learned on ARC).
I have created a map with population estimates and points. I created a buffer around the points of 75km and calculated the population within the buffers (There are overlaps that are not elegant, as they are multiple-counted but thats not my priority). I basically followed this introduction: Calculate number of people within 50 km of a point
Is there a way to calculate potential areas (in this case within europe), where my buffers miss out on largely populated areas?
Basically I would like to receive 75 km buffers located at those areas.
