-
MultiPoint.intersection()
returns a Geometry representing the shared area between a MultiPoint and another Geometry. -
This method accepts a
right
Geometry as input, along with optionalmaxError
andproj
parameters for reprojection control. -
The operation is performed in spherical coordinates with distances in meters by default, unless a projection is specified.
Usage | Returns |
---|---|
MultiPoint.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. |
