I am using ARCGIS 10.1. I am trying to calculate zonal statistics using as feature zone the world borders (http://thematicmapping.org/downloads/world_borders.php) and as input raster (http://webarchive.iiasa.ac.at/Research/LUC/GAEZ/plt/plates.htm PLATE 55). From plate 55 I extract values 1-3 to a new raster and I want to calcualte at the ISO 3 level the area occupied by these classes.
I reproject both files to a World_Cylindrical_Equal_Area projection so as to have minimum area distortions and I am trying to calculate zonal statistics.
However this does not work!
Then I tried to convert polygon to raster (using as a field the ISO3) and then do zonal statistics (same as above) but this does not work either.
Can please someone help?
Thanks in advance!
