intersection function

Returns a geometry that represents the shared portion of geometry a and geometry b.

Syntax

intersection( geometry a , geometry b)

Arguments

geometry → geometry geometry → geometry

Example

 geomToWKT( intersection( geomFromWKT( 'LINESTRING(3 3 , 4 4 , 5 5)' ) , geomFromWKT( 'LINESTRING(3 3 , 4 4 )' ))  )   → returns LINESTRING(3 3, 4 4)
