ee.Geometry.MultiPolygon.disjoint

AI-generated Key Takeaways

• The disjoint method returns true if and only if two geometries are disjoint.

• The method is used on a MultiPolygon object with a Geometry as the right operand and returns a Boolean.

• Optional arguments include maxError for tolerable error during reprojection and proj for specifying the projection.

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.

// Define a MultiPolygon object.

    [[[[-122.092, 37.424],
       [-122.086, 37.418],

// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);

// Apply the disjoint method to the MultiPolygon object.
var multiPolygonDisjoint = multiPolygon.disjoint({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('multiPolygon.disjoint(...) =', multiPolygonDisjoint);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPolygon,
             {'color': 'black'},

Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
