ee.Geometry.Polygon.coordinates

  • The coordinates() method returns a GeoJSON-style list of a geometry's coordinates.

  • It is applicable to Polygon geometries and returns a List object.

  • The returned list represents the coordinates that define the shape of the polygon.

  • Usage examples are provided in JavaScript and Python.

 Returns a GeoJSON-style list of the geometry's coordinates.

// 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');
