示例
代码编辑器 (JavaScript)
// Define a Rectangle object.
var rectangle = ee.Geometry.Rectangle(-122.09, 37.42, -122.08, 37.43);
// Apply the geodesic method to the Rectangle object.
var rectangleGeodesic = rectangle.geodesic();
// Print the result to the console.
print('rectangle.geodesic(...) =', rectangleGeodesic);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(rectangle,
{'color': 'black'},
'Geometry [black]: rectangle');
