Represents a relationship between two geometries (or the places they represent), relating a containing geometry to a contained geometry. "a contains b iff no points of b lie in the exterior of a, and at least one point of the interior of b lies in the interior of a". As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).

Represents a relationship between two geometries (or the places they represent), relating a geometry to another that covers it. As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).

Represents a relationship between two geometries (or the places they represent), relating a covering geometry to a covered geometry. "Every point of b is a point of (the interior or boundary of) a". As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).

Represents a relationship between two geometries (or the places they represent), relating a geometry to another that crosses it: "a crosses b: they have some but not all interior points in common, and the dimension of the intersection is less than that of at least one of them". As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).

Represents spatial relations in which two geometries (or the places they represent) are topologically disjoint: they have no point in common. They form a set of disconnected geometries." (a symmetric relationship, as defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM))

Represents spatial relations in which two geometries (or the places they represent) are topologically equal, as defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM). "Two geometries are topologically equal if their interiors intersect and no part of the interior or boundary of one geometry intersects the exterior of the other" (a symmetric relationship)

Represents spatial relations in which two geometries (or the places they represent) have at least one point in common. As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).

Represents a relationship between two geometries (or the places they represent), relating a geometry to another that geospatially overlaps it, i.e. they have some but not all points in common. As defined in [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM).
