ee.Geometry.LinearRing.intersects

AI-generated Key Takeaways

• The intersects method returns true if and only if the geometries intersect.

• The intersects method is used with a LinearRing object and requires a right geometry and optional maxError and proj arguments.

• The right argument is the geometry used as the right operand, and maxError is the maximum error tolerated during reprojection, while proj specifies the projection for the operation.

Returns true if and only if the geometries intersect.

Usage	Returns
LinearRing.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 LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

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

// Apply the intersects method to the LinearRing object.
var linearRingIntersects = linearRing.intersects({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('linearRing.intersects(...) =', linearRingIntersects);

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