Hi all.
I am gradually increasing my use of FME instead of ArcGIS for various operations. What i am working on now is to create a global vectorgrid in shape, with 0.5x0.5 decimal degree polygons. 205920 in total.

What i want to use this for is to collect dissaggregated data into each polygons attribute table.

In this case i want to summarize the percentage coverage of each raster within each of the polygon.
In arcgis i previously used the Zonal Statistics in Hawth Tools.

I now want to do this operation in FME. I have set up the operation and managed to create the vector grid, in addition to adding various variables to it.
Now i want to summarize rasters.

Thanks for all inputs on this!
Andreas
