I am trying to run a Summarize Within in ArcGIS Pro but am having trouble. I am looking for a quicker way to run a Summarize Within for about 15,000 input polygon circles (radius of 5 miles) summarizing a set of about 2000 unique input summary feature polygons. One input polygon is likely to overlap with several summary features, which is likely slowing down the tool. I have run a similar function except the input polygons had a 1 mile radius instead, and while it took some time, it did not take over 12 hours, program crashing, etc.
I was thinking of utilizing a for loop in the Python functionality for selecting pieces of the layer by ObjectID and running the tool several times automatically but hadn't figured out a way of doing so. Has anyone had this issue and figured out a workaround?
