Hello, I want to calculate the logarithmic average of the values of points as a raster. 

Has anyone ever tried to do this? 



Geometric mean explained by wikipedia:  "The geometric mean, in mathematics, is a type of mean or average, which indicates the central tendency or typical value of a set of numbers. It is similar to the arithmetic mean, which is what most people think of with the word "average", except that the numbers are multiplied and then the nth root (where n is the count of numbers in the set) of the resulting product is taken."
