In R, I have a raster stack with 6 variables. I would like to extract the mean and maximum value of each variable at 300 coordinates within a 500m buffer radius and a 1km buffer radius.
In ArcGIS 10.2 there are problems extracting variables from buffers if there is any overlap. Is this a problem in R?
If not, how do you make buffers around a point in R? And how would I extract the mean and maximum value at the two scales surrounding each point?
