用法返回
LinearRing.toGeoJSON()GeoJSONGeometry
参数类型详细信息
此：geometry几何图形Geometry 实例。

示例

代码编辑器 (JavaScript)

// Define a LinearRing object.
var linearRing = ee.Geometry.LinearRing(
    [[-122.091, 37.420],
     [-122.085, 37.422],
     [-122.080, 37.430]]);

// Apply the toGeoJSON method to the LinearRing object.
var linearRingToGeoJSON = linearRing.toGeoJSON();

// Print the result to the console.
print('linearRing.toGeoJSON(...) =', linearRingToGeoJSON);

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