Examples
Code Editor (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 toGeoJSON method to the Polygon object.
var polygonToGeoJSON = polygon.toGeoJSON();
// Print the result to the console.
print('polygon.toGeoJSON(...) =', polygonToGeoJSON);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(polygon,
{'color': 'black'},
'Geometry [black]: polygon');
