AI-generated Key Takeaways
-
Returns a new Geometry that represents the shared area between two input geometries.
-
Accepts two geometries as input:
left
(the geometry the method is called on) andright
. -
Can be performed using a specified projection (
proj
) or a spherical coordinate system with linear distances in meters if no projection is defined. -
Includes an optional
maxError
parameter to control the tolerance for reprojection errors.
Usage | Returns |
---|---|
Geometry.intersection(right, maxError, proj) | 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. |
