Hi, Hi, For a script I am working on, I am looking for a way to select a X number of raster cells and their values into a numpy array. I can create a layer with r.random, and read in that layer into a numpy array, but I rather avoid having to read in the whole raster layer. I can also from within the script run r.random to generate a raster layer, r.stats to export the resulting raster layer as a text file (with n flag), and than read in the text file in Python. But I wonder if there is not a more direct way to accomplish this.. You can read col and row from GRASS Region and use random python function to calculate random x and y and later query a pygrass raster object Cheers, Paulo Cheers Luca
