範例

程式碼編輯器 (JavaScript)

// Define a MultiLineString object.
var multiLineString = ee.Geometry.MultiLineString(
   [[[-122.088, 37.418], [-122.086, 37.422], [-122.082, 37.418]],
    [[-122.087, 37.416], [-122.083, 37.416], [-122.082, 37.419]]]);

// Apply the toGeoJSON method to the MultiLineString object.
var multiLineStringToGeoJSON = multiLineString.toGeoJSON();

// Print the result to the console.
print('multiLineString.toGeoJSON(...) =', multiLineStringToGeoJSON);

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