ee.Geometry.BBox.union
Returns the union of the two geometries.
Usage | Returns | BBox.union(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
Code Editor (JavaScript)
// Define a BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);
// Define other inputs.
var inputGeom = ee.Geometry.BBox(-122.085, 37.415, -122.075, 37.425);
// Apply the union method to the BBox object.
var bBoxUnion = bBox.union({'right': inputGeom, 'maxError': 1});
// Print the result to the console.
print('bBox.union(...) =', bBoxUnion);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(bBox,
{'color': 'black'},
'Geometry [black]: bBox');
Map.addLayer(inputGeom,
{'color': 'blue'},
'Parameter [blue]: inputGeom');
Map.addLayer(bBoxUnion,
{'color': 'red'},
'Result [red]: bBox.union');
