ee.Geometry.Point.difference

Returns the result of subtracting the 'right' geometry from the 'left' geometry.

UsageReturns
Point.difference(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.

Examples

Code Editor (JavaScript)

// 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 difference method to the Point object.
var pointDifference = point.difference({'right': inputGeom, 'maxError': 1});

// Print the result to the console.
print('point.difference(...) =', pointDifference);

// 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(pointDifference,
             {'color': 'red'},
             'Result [red]: point.difference');
