ee.Geometry.LinearRing.intersection
Returns the intersection of the two geometries.
Usage | Returns |
---|
LinearRing.intersection(right, maxError, proj) | Geometry |
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
// 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 intersection method to the LinearRing object.
var linearRingIntersection = linearRing.intersection({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('linearRing.intersection(...) =', linearRingIntersection);
// 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');
Map.addLayer(linearRingIntersection,
{'color': 'red'},
'Result [red]: linearRing.intersection');
