ee.Geometry.MultiPoint.getInfo
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
从服务器检索此对象的值。
如果未提供回调函数，则以同步方式发出请求。如果提供了回调，则会异步发出请求。
建议使用异步模式，因为同步模式在等待服务器时会停止所有其他代码（例如 EE 代码编辑器界面）。如需发出异步请求，建议使用 evaluate() 而不是 getInfo()。
返回此对象的计算值。
| 用法 | 返回 |
|---|
MultiPoint.getInfo(callback) | 对象 |
| 参数 | 类型 | 详细信息 |
|---|
此：computedobject | ComputedObject | ComputedObject 实例。 |
callback | 函数（可选） | 可选的回调。如果未提供，则以同步方式进行调用。 |
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 getInfo method to the MultiPoint object.
var multiPointGetInfo = multiPoint.getInfo();
// Print the result to the console.
print('multiPoint.getInfo(...) =', multiPointGetInfo);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(multiPoint,
{'color': 'black'},
'Geometry [black]: multiPoint');
