|
|
*Parameters*
|
|
|
|
`geomA`::
|
|
Expression of type `geo_point`, `cartesian_point`, `geo_shape` or `cartesian_shape`. If `null`, the function returns `null`.
|
|
|
|
`geomB`::
|
|
Expression of type `geo_point`, `cartesian_point`, `geo_shape` or `cartesian_shape`. If `null`, the function returns `null`.
|
|
The second parameter must also have the same coordinate system as the first.
|
|
This means it is not possible to combine `geo_*` and `cartesian_*` parameters.
|
|
|
|
*Description*
|
|
|
|
Returns true if two geometries intersect.
|
|
They intersect if they have any point in common, including their interior points
|
|
(points along lines or within polygons).
|
|
In mathematical terms: ST_Intersects(A, B) ⇔ A ⋂ B ≠ ∅
