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

[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The `geometries()` method extracts geometries from a `GeometryCollection` or returns a singleton list containing the geometry itself. For example, applying `geometries()` to a `LinearRing` object, as demonstrated in both JavaScript and Python examples, results in a list. The code shows the creation of a `LinearRing`, the application of `.geometries()`, the printing of the result, and the visualization on a map using specified coordinates and color.\n"],null,[]]
