I used the dissolve boundaries tool dissolving by field value to group polygons by year of treatment. Now I have dissolved polygons with hundreds of holes that need to be removed (please see picture). I want to keep only the outer polygon boundaries.
A similar question was asked as Extracting outer boundary of polygon (current polygon merged to one row but layer has holes creating small polygon needing removal) using ArcGIS Pro, but solutions provided were useful for small edits.
Is there an automated solution for hundreds of edits?
