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');
