Intersection error issue

Im trying to determine if 1307 or 1303 occupies more of the blue polygon. I need to do this for a series of polygons and want to automate this step this using python.

for c_id, geometry_c in c_geometries.items(): largest_intersection_h_id = None largest_intersection_area = 0 for h_id, geometry_h in h_geometries.items(): intersection = geometry_c.intersect(geometry_h, 4) intersection_area = intersection.area if intersection_area > largest_intersection_area: largest_intersection_area = intersection_area largest_intersection_h_id = h_id if largest_intersection_h_id is not None: c_h_dict[c_id] = largest_intersection_h_id for c_id, h_id in c_h_dict.items(): print(c_id, h_id)

I get this error message when I try this code

Thanks for the help!

Hi @V1212

I wrote a tool over here that might help: https://learn.finaldraftmapping.com/polygon-polygon-overlap-percentage-in-arcgis-pro-with-pairwise-intersect-and-arcpy/

You could use the tool, or refactor the code to suit your needs.
