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 uses object shapes.
