USGS Landsat 1 MSS Collection 2 Tier 1 原始场景
Landsat 1 MSS 集合 2 第 1 层级 DN 值,表示经过放大和校准的传感器端辐射度。数据质量最高的 Landsat 场景会被划分到第 1 层级,并且被视为适合进行时间序列处理分析。第 1 层级包括经过处理的第 1 级精确地形 (L1TP) 数据,具有以下特点: c2 全球 l1 landsat lm1 mss -
USGS Landsat 1 MSS Collection 2 Tier 2 原始场景
Landsat 1 MSS 集合 2 第 2 层级 DN 值,表示经过放大和校准的传感器端辐射度。在处理过程中,如果场景不符合第 1 层级的条件,则会被分配到第 2 层级。这包括系统地形 (L1GT) 和系统 (L1GS) 处理过的场景,以及满足以下条件的任何 L1TP 场景: c2 全球 l1 landsat lm1 mss
