[GRASS-user] zonal statistics for multiple areas

Hi Alessandro,

You could try v.rast.bufferstats [1], if you do not have hundrets of thousands of points….

If the buffers don`t overlap, you could use v.rast.stats [2] from the upcoming GRASS 7.6 release, that will allow multiple raster input…

Otherwise have a look at the general introduction to GRASS and Python [3].

Subject: [GRASS-user] zonal statistics for multiple areas

Hello to everybody,
I hope my question is appropriate for this mail list. I have created 5 different buffer layers (d=100,200,300,400,500 m) from a point vector. Now i want to compute some zonal statistics using different rasters as input. I know how to do that separately, but i was wondering how could i automate this procedure using a python script. I know python's basics, but i was not able to do so following guidelines that i found on the internet, e.g GRASS tutorial. Thank you in advance, A
