ee.Geometry.MultiLineString.centroid

Returns a point at the center of the highest-dimension components of the geometry. Lower-dimensional components are ignored, so the centroid of a geometry containing two polygons, three lines and a point is equivalent to the centroid of a geometry containing just the two polygons.
UsageReturns
MultiLineString.centroid(maxError, proj)Geometry
ArgumentTypeDetails
this: geometryGeometryCalculates the centroid of this geometry.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the result will be in this projection. Otherwise it will be in WGS84.

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 centroid method to the MultiLineString object.
var multiLineStringCentroid = multiLineString.centroid({'maxError': 1});

// Print the result to the console.
print('multiLineString.centroid(...) =', multiLineStringCentroid);

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