I read online about: Web23.1. What is Validity ¶. Validity is most important for polygons, which define bounded areas and require a good deal of structure. Lines are very simple and cannot be invalid, nor can points. Some of the rules of polygon validity feel obvious, and others feel arbitrary (and in fact, are arbitrary). Polygon rings must close.
