I was wondering if it exists a way to create variable buffers where the radius is given by a process of maximization of the mean value of a raster.

I have a point vector data and I would like to create variable circular buffers around these points where the variable distance is given by a process of maximization. In particular, the variable distance has to be the one that maximize the mean population in the buffer zone (and I have a raster of the population in a given country).

In the end should be something like in the picture but the radius should be the result of the maximization process described above.

There is some plugin able to do that?

  • Raster data cannot be buffered, you need vector data. – Erik Oct 29 '19 at 10:01
  • Sorry for my inaccuracy in posing the question. I have a point-vector data and I would like to create circular buffer zones around these point where the radius is given by a process of maximization of the mean of the underling raster – DavZf Oct 29 '19 at 10:05
  • Please edit your question accordingly. Also, could you explain what "a process of maximization of the mean of the underlying raster" does mean (to you)? – Erik Oct 29 '19 at 10:07
  • Again sorry. I have edited my question. Now it is clear what I mean? – DavZf Oct 29 '19 at 10:11
  • So... your buffer should be of such a size, that the mean population inside it is the highest possible value? – Erik Oct 29 '19 at 10:14
