根据您的偏好保存内容并对其进行分类。
Earth Engine API 由对象和方法组成。对象表示光栅图片、矢量地图项、数字和字符串等数据类型。这些对象各自属于特定类,并且每个类都有一组严格的函数可供使用。
对象和方法会在工作流脚本中组合,并发送到 Earth Engine 服务器进行处理。点击以下卡片查看示例流程,了解常见的对象类及其方法。
如需查看 Earth Engine 类及其方法的完整列表,请参阅 API 参考指南的客户端库部分(例如 ee.Image.add
)。您也可以在 JavaScript 代码编辑器的 Docs 标签页下找到相同的参考信息。

Objects represent data\ntypes such as raster images, vector features, numbers, and strings.\nEach of these objects belongs to a specific class, and each class has a\nstrict set of functions available to it.\n\nObjects and methods are combined in workflow scripts and sent to Earth Engine\nservers for processing.
