ee.Geometry.Point.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.

Usage	Returns
Point.centroid(maxError, proj)	Geometry

Argument	Type	Details
this: geometry	Geometry	Calculates the centroid of this geometry.
maxError	ErrorMargin, default: null	The maximum amount of error tolerated when performing any necessary reprojection.
proj	Projection, default: null	If specified, the result will be in this projection. Otherwise it will be in WGS84.

Examples

Code Editor (JavaScript)

// Define a Point object.
var point = ee.Geometry.Point(-122.082, 37.42);

// Apply the centroid method to the Point object.
var pointCentroid = point.centroid({'maxError': 1});

// Print the result to the console.
print('point.centroid(...) =', pointCentroid);

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