ee.Geometry.MultiPolygon.intersection

Returns the intersection of the two geometries.

UsageReturns
MultiPolygon.intersection(right, maxError, proj)Geometry
ArgumentTypeDetails
this: leftGeometry

The geometry used as the left operand of the operation.

rightGeometry

The geometry used as the right operand of the operation.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, 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.
var multiPolygon = ee.Geometry.MultiPolygon(
    [[[[-122.092, 37.424],
       [-122.086, 37.418],
       [-122.079, 37.425],
       [-122.085, 37.423]]],
     [[[-122.081, 37.417],
       [-122.086, 37.421],
       [-122.089, 37.416]]]]);

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

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

// Print the result to the console.
print('multiPolygon.intersection(...) =', multiPolygonIntersection);

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