I have a polygon shapefile in desktop 10.7 in which some of the polygons overlap partly or totally. Is there a simple way to create records of these 'shared' areas which retain the attributes of both?
The best I have been able to come up with is a Union geoproccess using the same layer twice. The problem with this is that is created 4 records for the shared area. If the overlapping polygons were called A and B the 4 shared areas would include records with fields A+A, B+B, A+B and B+A. By adding a field, calculating the area of each polygon, and identifying the polygons with the same area I can identify the duplicate records and delete 3 of the 4, but hope to find a simpler solution.
The attachment show what I hope to achieve. If I start with 2 polygons called A and B I want to end up with 3, the unshared part of A, the unshared part of B, and the shared area.
