Hi Sarmistha,
1 - I am using ArcPro 2.6.3
2 - Raster cell size is 0.083333 x 0.083333
3 - No. I didn't change any environment option because I wanted to compare what would be the results without other software that do it with default parameters.
3.A - After posting this screenshot I tried some other options. I reduced the cell size in half and I also tried to rasterize the feature layer and use it as the input zona data. The results were not good.
The data is freely available and it shouldn't take much time to get it.
The GADM Level 1 (States/Provinces administrative borders) can be downloaded as Shapefile from gadm.org/download_world.html
Using the link "shapefiles" after "download this version as six separate layers" and
The Level 1 layer have the file name "gadm36_1.shp"
For the raster value file, I am using is the SPAM Palm Oil global production map from 2010.
It can be downloaded from mapspam.info/data/
Search for "SPAM 2010 v2.0 Global Data (Updated 2020-07-15)" and "Production" Geotiff
The Palm Oil Geotiff goes file name is "spam2010V2r0_global_P_OILP_A.tif"
Thank you so very much and my regards to the team.
Ivan
