box2d — A 2-dimensional bounding box. Used to describe the 2D extent of a geometry or collection of geometries.
Description
box2d
is a spatial data type used to represent
the two-dimensional enclosing box of a geometry or collection of geometries.
For example, the

aggregate function returns a
box2d

.
These are the minimum and maxium values of the X and Y extents.
