ee.Geometry.Polygon.intersects

Returns true if and only if the geometries intersect.

Usage	Returns
`Polygon.intersects(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.

Examples

Code Editor (JavaScript)

// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
    [[[-122.092, 37.424],
      [-122.086, 37.418],
      [-122.079, 37.425],
      [-122.085, 37.423]]]);

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

// Apply the intersects method to the Polygon object.
var polygonIntersects = polygon.intersects({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('polygon.intersects(...) =', polygonIntersects);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
             {'color': 'black'},
             'Geometry [black]: polygon');
Map.addLayer(inputGeom,
             {'color': 'blue'},
             'Parameter [blue]: inputGeom');
