Many polygons in Layer1 are very close together and overlap quite a bit, so the output layer has many slivers of the same census block group in Layer1. Is there a way to keep the intersect output from splitting the intersected Block Group between the overlapping polygons?&nbsp; I tried ranking Layer1 as 1, but it didn't seem to have any effect. I've attached two images to help illustrate my issue.&nbsp; Thanks for any insight you might have!
