I did a topology check on a polygon layer. It turns out I have line errors "Must not have gaps". I don't understand as there are no gaps in the polygons.
I attached an image, the errors are the red lines. There is only one big polygon because I merged the islands with a Country.
Any idea on what could cause this error and how to fix it?
To fix try tool Repair Geometry:
Inspects each feature in a feature class for geometry problems. Upon discovery of a geometry problem, a relevant fix will be applied, and a one-line description will be printed identifying the feature as well as the problem encountered.
