I am currently working on a way of efficiently displaying information relating to tree inspections (using ArcGIS Desktop to then upload onto arcgis online so that the data can be accessed and added to on the collector app). The end goal is to be able to access all past inspections relating to a tree on the collector app and add new inspections through the app.
I want to form a 1:many relationship class between a point feature (the tree) and inspections.
I know this is possible, however, I am not sure how to format the data I have so that I am able to form the relationship. I currently have 3 years worth of inspection data, but each set of data has its own shapefile layer for trees.
How do I go about formatting the data so that I can create a 1:many relationship?
