I want the rings to be from 0 - 2km, 2km - 5km, 5km - 10km. I'm using the multi-ring buffer in QGIS and it doesn't have the option to specify the radius of each circle separately so I can make them each have a difference of 5 or 2 but its has to be the same across. Is there a way to make the radius of each circle different in QGIS.</p> <p>I tried using difference by making a 0-2km buffer and then a 0-5km buffer but I have over 1000 points which are close together and so the buffer for each unique point overlaps. This means that difference removes regions for all overlapping buffers for other points (which I dont want). The picture shows you what I'm working with where the brown dots are my unique points and the pink buffers are the 2km buffers while the orange ones are the 5km buffers.</p> <p><a
