ee.Geometry.MultiPolygon.disjoint
Stay organized with collections
Save and categorize content based on your preferences.
Returns true if and only if the geometries are disjoint.
| Usage | Returns | MultiPolygon.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. |
