示例

代码编辑器 (JavaScript)

// Define a Polygon object.
var polygon = ee.Geometry.Polygon(
    [[[-122.092, 37.424],
      [-122.086, 37.418],
      [-122.079, 37.425],
      [-122.085, 37.423]]]);

// Apply the coordinates method to the Polygon object.
var polygonCoordinates = polygon.coordinates();

// Print the result to the console.
print('polygon.coordinates(...) =', polygonCoordinates);

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