box2d
Name
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
   
    ST_Extent
   
   aggregate function returns a
   
    box2d
   
   object.
  
   The representation contains the values
   
    xmin, ymin, xmax, ymax
   
   .
				These are the minimum and maxium values of the X and Y extents.
