-
intersects()
returns true if a geometry intersects with another geometry, meaning they share any portion of space. -
This method takes a Geometry as input (
right
) and optional error margin (maxError
) and projection (proj
) parameters. -
The operation can be performed in spherical coordinates with distances in meters or a specified projection.
-
It's commonly used for spatial analysis tasks like finding overlapping areas or features.
Usage | Returns |
---|---|
Polygon.intersects(right, maxError, proj) | Boolean |
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. |
