CG_Intersects — Tests if two geometries intersect (they have at least one point in common)
boolean CG_Intersects(
geometry
geomA
,
geometry
geomB
)
;
Returns true
if two geometries intersect.
Geometries intersect if they have any point in common.
Performed by the SFCGAL module
NOTE: this is the "allowable" version that returns a boolean, not an integer. |
Availability: 3.5.0
This method needs SFCGAL backend.
This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
