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

[null,null,["最后更新时间 (UTC):2025-07-26。"],[],["The `isUnbounded()` method, applicable to `Geometry` objects like `MultiPoint`, determines if a geometry is unbounded, returning a Boolean. It takes a `Geometry` object as input and returns `true` if the geometry is unbounded, and `false` otherwise. Examples show creating a `MultiPoint` object and applying `isUnbounded()`, printing the Boolean result, then displaying the geometry. Both JavaScript and Python code are provided.\n"],null,[]]
