ee.Geometry.MultiPoint.dissolve

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

Usage	Returns
MultiPoint.dissolve(maxError, proj)	Geometry

Argument	Type	Details
this: geometry	Geometry	The geometry to union.
maxError	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
proj	Projection, default: null	If 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 MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);

// Apply the dissolve method to the MultiPoint object.
var multiPointDissolve = multiPoint.dissolve({'maxError': 1});

// Print the result to the console.
print('multiPoint.dissolve(...) =', multiPointDissolve);

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