ee.Geometry.Rectangle.dissolve

Returns the union of the geometry. This leaves single geometries untouched, and unions multi geometries.

UsageReturns
Rectangle.dissolve(maxError, proj)Geometry
ArgumentTypeDetails
this: geometryGeometryThe geometry to union.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the union will be performed in this projection. Otherwise it will be performed in a spherical coordinate system.

Examples

Code Editor (JavaScript)Colab (Python)
// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);

// Apply the dissolve method to the Rectangle object.
var rectangleDissolve = rectangle.dissolve({'maxError': 1});

// Print the result to the console.
print('rectangle.dissolve(...) =', rectangleDissolve);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
             {'color': 'black'},
             'Geometry [black]: rectangle');
Map.addLayer(rectangleDissolve,
             {'color': 'red'},
             'Result [red]: rectangle.dissolve');
