// 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 geometries method to the MultiLineString object.
var multiLineStringGeometries = multiLineString.geometries();
// Print the result to the console.
print('multiLineString.geometries(...) =', multiLineStringGeometries);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiLineString,
{'color': 'black'},
'Geometry [black]: multiLineString');

[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The `geometries()` method extracts and returns a list of geometries from a `GeometryCollection` or a single geometry within a list. For example, applied to a `MultiLineString`, it yields a list of its constituent line geometries. The method accepts a `geometry` as an argument. Both JavaScript and Python examples demonstrate creating a `MultiLineString`, applying `geometries()`, printing the result, and visualizing the geometry on a map.\n"],null,[]]
