We have zoning snapshots from pre-2000 that were saved as ArcInfo coverages. Because ArcGIS Pro can't read coverages, we are working on a python script to convert them to file geodatabase feature classes and annotation. Quick question: were the AREA and PERIMETER 'items' (fields) in a polygon attribute table maintained by the ArcInfo software, similarly to how ArcGIS maintains the shape_area and shape_length in geodatabases these days? I think the answer was yes, but it would be good to get some confirmation. Also, could ArcInfo users edit the AREA and PERMITER fields? Again, I think I know the answer: No. But please confirm.
I can't confirm (or deny) what you are asking, but if my memory serves me and it's up to a bet, my money is on what you think. Good ol' ArcInfo maintained Area & Perimeter but a user could not edit those values.
Maybe it was just conventional wisdom to not to edit them.
