Checks if two geometries overlap. Returns 1 if they share space but neither completely contains the other, and they have the same dimension.
ST_OVERLAPS(g1,g2)Returns 1 or 0 to indicate whether geometry g1 spatially overlaps geometry g2.
The term spatially overlaps is used if two geometries of equal dimensions intersect and their intersection results in a geometry of the same dimension but not equal to either of the given geometries.
ST_OVERLAPS() uses object shapes, while , based on the original MySQL implementation, uses object bounding rectangles.
