[Qgis-user] Zonal Statistics multiple classe

[Nicolas Cadieux]

Hi,

I have a raster (int16) with multiple class (ex 1 = grass, 2 = trees...) 
and a vector polygon file.  I want to have the zonal statistic (cum, 
min, max, sum...) for every class.  What is the best way to get this 
done in QGis 2.18.16 on Windows 10?

Thanks,

Nicolas
