Polygon to raster with weighted average cell assignment?

s_jacob

I was just using the polygon to raster tool and noticed that cell assignment type doesn't include the option to perform a weighted average of overlapping polygons. For example if a layer has a bunch of polygons (circles) where multiple would fall within the same raster cell (say around 10), could the raster value be based on a weighted average of the polygons' value? Is there another way around doing this in ArcGIS Pro?

Ah this took some head scratching but I think the best way is to run Feature to Polygon on your single FC

which will break up the features where they intersect and preserve non intersecting similar to Union.

Next step is a spatial join with a field merge rule of Mean on your value field.

Target = Feature to Polygon output, Join = Original FC,  Match = Intersect, Field Map Merge Rule = Mean

Final step will be to run your Polygon to Raster .
