AI-generated Key Takeaways
-
The
disjoint()
method returns true only if the geometries do not share any points. -
It is applied to a MultiPoint geometry (the
left
operand) and takes another geometry (right
) as input for comparison. -
Optional parameters include
maxError
for reprojection tolerance andproj
to specify the projection for the operation. -
The examples demonstrate how to use
disjoint()
in JavaScript and Python to determine if a MultiPoint and a Bounding Box are disjoint.
Usage | Returns |
---|---|
MultiPoint.disjoint(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. |
