Hi Stefan, Yes, I read the issue in the link that you gave me. In one thread, there is an issue of both zonal statistics plugin and zonal statistics in processing toolbox are not working. But in my case the ZonalStats Plugin is working and the other is not. I browsed my data again and found that some polygons are not in the middle of the raster. However, it seems that ZonalStats plugin considers the polygons even though other the polygons are not in the center of the raster. Is there a difference between the algorithm between the two ZonalStats option. By the way, I am using the ZonalStatistics under *QGIS geoalgorithms* > *Raster tools*.
Is there something that I missed from the threads that you shared with me? Thanks for the help. -Leo On Fri, Mar 13, 2015 at 8:38 AM, Leo Kris Palao <[email protected]> wrote: > HI Stefan, > > Yes, I read the issue in the link that you gave me.
