I am clipping a raster and then running RasterStatisticsCalculator. The results are completely wrong to what I get in ESRI using zonal statistics and the only stat that is correct is the max value.
FME Results:
When I export the raster and bring it into ESRI, cell values are different and zonal stats are different
Zonal stats results from ESRI:
I would appreciate some help in how best to run zonal stats in FME.
Thanks,

I wonder what the results are if you do the statistics calculation before you do the clipping.
I’ve seen sometimes certain operations can get done out of order, I wonder if something like that is happening here. It probably wont change anything but you could try and run a RasterCheckpointer in between the clip and statistics calculator.
Some insight into how fme processes rasters can be found here: https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Transformers/Transformers/rastercheckpointer.htm
