AI-generated Key Takeaways
-
Returns a Geometry representing the shared area between two geometries.
-
Takes a Geometry as the right operand and optional
maxError
andproj
parameters. -
Can be applied to Point objects to find the intersection with other geometries like bounding boxes.
-
The operation is performed in a spherical coordinate system by default, using meters as the unit for linear distances.
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. |
