AI-generated Key Takeaways
-
The
intersectionmethod returns the intersection of two geometries. -
This method can be applied to a Point geometry and takes a right geometry operand, an optional maximum error tolerance, and an optional projection as arguments.
-
The method returns a Geometry object representing the intersection.

Geometry |
| Argument | Type | Details |
|---|---|---|
|
this:
left
|
Geometry | The geometry used as the left operand of the operation. |
right
|
Geometry | The geometry used as the right operand of the operation. |
maxError
|
ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj
|
Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |
