第一输入——时间集 dates ——放在.map()的左侧。第二输入——数据集hourly_temp ——就让外函数括起来。然后,在整个语句的最外层,用ee.ImageCollection()套起来,把.map()的输出结果(原本是ee.List)转换成图像集。 var daily_temp = ee.ImageCollection(dates.map(calc_daily_mean(hourly_temp))); 最后,让...

当您在Earth Engine上编写脚本时(无论JavaScript还是Python),该代码不会直接在谷歌的Earth Engine服务器上运行。相反,客户端库将脚本编码为一组JSON对象,将对象发送给谷歌并等待响应。每个对象表示获得特定输出所需的一组操作,例如,要在客户端上显示的图像。 进一步解释一下:代码写好之后,只会在本地做解析。本地端...
