GEE更新——Landsat数据更新Landsat C01 向 C02 迁移旧数据2024年7月1日停用

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。
