This is a very basic question, but I'm just stumped. I'm a GIS student.
I'm being asked to create a unique ID in a database. There are five separate feature classes (five different states with geocoded data) within the file geodatabase. How do I create a UID for the whole thing? Or do I just create a field in each feature with UIDs and accept that each one will have overlapping UIDs?
Does this make any sense?
Thanks so much for any help you can give,
