谷歌地球引擎 -- Landsat 5 TM_TOA DN 比例校准传感器辐射度数据集
Landsat 5 TM Collection 1 Tier 2 DN values, representing scaled, calibrated at-sensor radiance.
Scenes not meeting Tier 1 criteria during processing are assigned to Tier 2. This includes Systematic terrain (L1GT) and Systematic (L1GS) processed scenes, as well as any L1TP scenes that do not meet the Tier 1 specifications due to significant cloud cover, insufficient ground control, and other factors. Users interested in Tier 2 scenes can analyze the RMSE and other properties to determine the suitability for use in individual applications and studies. See more information in the USGS docs.

Landsat 5 TM Collection 1 Tier 2 DN值,代表缩放的、校准的传感器辐射度。
在处理过程中不符合第1级标准的场景被分配到第2级。这包括系统地形(L1GT)和系统(L1GS)处理的场景,以及任何L1TP场景,这些场景由于严重的云层覆盖、地面控制不足和其他因素而不符合第1级规格。对第2级场景感兴趣的用户可以分析RMSE和其他属性,以确定是否适合用于个人应用和研究。参见USGS文档中的更多信息。
