ee.Geometry.BBox.dissolve

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

UsageReturns
BBox.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)

// Define a BBox object.
var bBox = ee.Geometry.BBox(-122.09, 37.42, -122.08, 37.43);

// Apply the dissolve method to the BBox object.
var bBoxDissolve = bBox.dissolve({'maxError': 1});

// Print the result to the console.
print('bBox.dissolve(...) =', bBoxDissolve);

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