GEE数据集重大更新:Landsat C01数据将在7月下线,更新方案已给出
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。
Landsat C01和C02的数据
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。
