Editor de código (JavaScript)
// Define a Polygon object.
var polygon = ee.Geometry.Polygon(

// Apply the geodesic method to the Polygon object.
var polygonGeodesic = polygon.geodesic();
// Print the result to the console.
print('polygon.geodesic(...) =', polygonGeodesic);
// Display relevant geometries on the map.
