I merged a population raster with polygons (buffer) to find out how many inhabitants live in each polygone (buffer). 

 

I used the spatial filter for this operation and the results are mostly satisfying. There is one case when the results seem to be wrong : that is when I have overlapping polygons. In that case, each population raster in only use for one polygon. Which setting should I change to make sure that the entire population raster is checked for each polygon (buffer) in order to have the correct value for population?

Hi ​@fme_junior ,

I think you can use SpatialRelator in order to merge all attributes of spatially related Supplier features as list to each Requestor feature. Check the Generate List parameter in the transformer.
