FeatureCollection.serialize(legacy) | 字符串 |
| 参数 | 类型 | 详细信息 |
|---|
此：computedobject | ComputedObject | ComputedObject 实例。 |
legacy | 布尔值，可选 | 启用旧版格式。 |
示例
代码编辑器 (JavaScript)
// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');
print('Serialized representation of ee.FeatureCollection', fc.serialize());
Python 设置
如需了解 Python API 和如何使用 geemap 进行交互式开发，请参阅
Python 环境页面。
import ee
import geemap.core as geemap
Colab (Python)
# FeatureCollection of power plants in Belgium.
fc = ee.FeatureCollection('WRI/GPPD/power_plants').filter(
'country_lg == "Belgium"')
print('Serialized representation of ee.FeatureCollection:',
fc.serialize())
