I am working on a map of various building locations (this is a point feature class) and parcels (polygon feature class). Each parcel has anywhere from 0 to many buildings on it (including parts of buildings) and conversely, each building is on one or more parcels (some buildings straddle parcels).
I am creating the map in ArcGIS Pro and intend to publish it to ArcGIS Online. I am working with a 'basic' license of Pro, so I don't think I can create relationship classes.
I would like to be able to relate the building and parcel information so that someone can view a parcel's information and see what buildings are related to it, and conversely view a building's information to see the related parcels.
What is the best way to accomplish this?
