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.

Rectangle.centroid(maxError, proj)Geometry
this: geometryGeometry

Calculates the centroid of this geometry.

maxErrorErrorMargin, default: null

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

projProjection, default: null

If specified, the result will be in this projection. Otherwise it will be in WGS84.

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

// Apply the centroid method to the Rectangle object.
var rectangleCentroid = rectangle.centroid({'maxError': 1});

// Print the result to the console.
print('rectangle.centroid(...) =', rectangleCentroid);

// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
