I have a digitised map of Ireland, consisting of 40 features where each feature is a different polygon representing an Irish constituency.
I have created a topology to help me identify gaps and overlaps in the map. The overlaps works fine, but unfortunately, Ireland consists of more than 800 islands (ironically). This means it comes up with a lot of gap errors (typically around 870), since these island polygons are not surrounded by another polygons.
The gaps I do want to find and correct are gaps within the mainland, between polygons, and donut holes. This means I have to go through 800+ errors individually to possibly find an actual error I want to correct.
I was wondering if there was another way of doing this, so I can ignore the island polygons, and find real gaps and errors within the mainland? Trudging through nearly 900 errors to find one actual error is tough work!
