Returns the intersection of the two geometries.
Usage
Returns
Point.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.

It takes a `right` geometry as input, alongside optional `maxError` and `proj` parameters. `maxError` defines the tolerated error during reprojection, and `proj` specifies the projection for the operation. The method returns a new Geometry representing the intersection.
