示例
代码编辑器 (JavaScript)
// Define a MultiPoint object.
var multiPoint = ee.Geometry.MultiPoint([[-122.082, 37.420], [-122.081, 37.426]]);
// Apply the serialize method to the MultiPoint object.
var multiPointSerialize = multiPoint.serialize();
// Print the result to the console.
print('multiPoint.serialize(...) =', multiPointSerialize);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPoint,
{'color': 'black'},
'Geometry [black]: multiPoint');
