OVERLAPS

Synonym for ST_OVERLAPS. Checks if two geometries overlap, sharing some but not all points, and having the same dimension.

Syntax

OVERLAPS(g1,g2)

Description

Returns 1 or 0 to indicate whether g1 spatially overlaps 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.

OVERLAPS() is based on the original MySQL implementation and uses object bounding rectangles, while ST_OVERLAPS() uses object shapes.
