ST_MakeBox2D — Creates a BOX2D defined by two 2D point geometries.
box2d ST_MakeBox2D(geometry pointLowLeft, geometry pointUpRight);
Creates a box2d defined by two Point geometries. This is useful for doing range queries.
--Return all features that fall reside or partly reside in a US national atlas coordinate bounding box
--It is assumed here that the geometries are stored with SRID = 2163 (US National atlas equal area)
