ee.Geometry.Point.intersection
Returns the intersection of the two geometries.
Usage | Returns |
---|
Point.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 Point object.
var point = ee.Geometry.Point(-122.082, 37.42);
// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the intersection method to the Point object.
var pointIntersection = point.intersection({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('point.intersection(...) =', pointIntersection);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(point,
{'color': 'black'},
'Geometry [black]: point');
Map.addLayer(inputGeom,
{'color': 'blue'},
'Parameter [blue]: inputGeom');
Map.addLayer(pointIntersection,
{'color': 'red'},
'Result [red]: point.intersection');
Python setup
See the
Python Environment page for information on the Python API and using
geemap
for interactive development.

# Print the result.

It takes a `right` geometry as input, alongside optional `maxError` and `proj` parameters. `maxError` defines the tolerated error during reprojection, and `proj` specifies the projection for the operation. The method returns a new Geometry representing the intersection.
