更新通知

Attention Required! You're using a deprecated asset. To ensure continued functionality, please update it by July 1st, 2024.

本指南提供从大地遥感卫星第 1 集数据切换到第 2 集数据的说明。自 2022 年起,地球引擎已全面提供第 2 集数据,自 2021 年 12 月 31 日起,美国地质调查局已不再制作第 1 集数据。大地遥感卫星合集 1 已废弃,鼓励所有用户尽快迁移到合集 2。

每个大地遥感卫星数据集都代表一个版本的影像档案,这些影像档案是用一致的方法和程序处理的。随着系统和处理算法的改进,会生成新的合集。2020 年,美国地质调查局开始将档案重新处理为第 2 集。请参阅《Remote Sensing of Environment》(《环境遥感》)中的文章 "The 50-year Landsat collection 2 archive",了解集合处理模式背后的原理以及集合 2 提供的内容和进步。

以下各节介绍了每个大地遥感卫星数据产品从第 1 集迁移到第 2 集所需的更改,包括影像和集合 ID、波段名称、新波段、波段值缩放和位掩码值。各节中的内容选项卡提供了特定传感器的详细信息。

              .addBands(thermalBand, null, true);
}

var srColScaled = srCol.map(applyScaleFactors)

图像属性

在从资料集 1 到资料集 2 的过渡过程中,增加和删除了一些图像属性。太阳几何图形的属性有所改变。请参阅下面的属性对照表,以确定是否需要修改代码以适应丢失、添加或更改的属性(例如,在过滤或处理过程中)。有关 Collection 2 属性说明,请参阅产品样本页中的 "图像属性 "选项卡。
