What is the relationship type that indicates a has points inside b without any boundary contact?

The relationship type that accurately indicates a situation where one feature, represented as "a," has points that are entirely contained within another feature "b" without any boundary contact is referred to as "Contain." This describes a specific spatial relationship where feature "a" exists entirely within the confines of feature "b."

In geographic information systems (GIS), the "Contain" relationship specifies that all points of feature "a" are located inside the area defined by feature "b." Importantly, this relationship also emphasizes that there is no overlap at the borders or boundaries of the two features, meaning that "a" does not touch the boundary of "b" at all.

Understanding this relationship is crucial for spatial analysis in GIS because it allows for precise modeling of scenarios where one entity is nested within another, which can be important for a variety of applications such as environmental studies, land use planning, and resource management.

The other relationship types, such as "Disjoint," "Touch," and "Intersect," define different types of spatial interactions that do not match the criteria of having no boundary contact while remaining contained within another feature.
