Zonal Histogram Python

Zonal Histogram Python. First we need to get the values of the dem as numpy array and the affine of the raster. # read the raster values array = dem.read(1) # get the affine affine.

I would like to use zonal histogram to produce tables (and later xlxs files) with two columns: Histogram (a, bins = 10, range = none, normed = none, weights = none, density = none) [source] # compute the histogram of a dataset. This article shows how to implement a zonal statistics algorithm in python in 4 steps.
