ee.Geometry.MultiLineString.dissolve

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

UsageReturns
MultiLineString.dissolve(maxError, proj)Geometry
ArgumentTypeDetails
this: geometryGeometry

The geometry to union.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, 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 MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the dissolve method to the MultiLineString object.
var multiLineStringDissolve = multiLineString.dissolve({'maxError': 1});

// Print the result to the console.
print('multiLineString.dissolve(...) =', multiLineStringDissolve);

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