USGS Landsat 4 MSS Collection 2 Tier 1 Raw Scenes
Landsat 4 MSS Collection 2 Tier 1 DN 值,代表經過縮放及校正的感應器輻射。資料品質最高的可取得 Landsat 場景會歸入第 1 層,並視為適合用於時間序列處理分析。第 1 層包含經過 Level-1 精確地形 (L1TP) 處理的資料,這些資料… c2 global l4 landsat lm4 mss -
USGS Landsat 4 MSS Collection 2 Tier 2 Raw Scenes
Landsat 4 MSS Collection 2 Tier 2 DN 值,代表經過縮放及校正的感應器輻射率。如果影像在處理期間未達到第 1 級標準,系統會將其指派至第 2 級。包括系統性地形 (L1GT) 和系統性 (L1GS) 處理的影像,以及因雲量過多、地面控制不足和其他因素,不符合第 1 級規格的任何 L1TP 影像。 c2 global l4 landsat lm4 mss

[null,null,[],[],["Landsat 4 MSS Collection 2 data is categorized into Tier 1 and Tier 2. Tier 1 scenes contain the highest quality data suitable for time-series analysis, specifically Level-1 Precision Terrain (L1TP) processed data. Tier 2 includes scenes that do not meet Tier 1 criteria, such as Systematic terrain (L1GT) and Systematic (L1GS) processed scenes. Both tiers contain DN values representing scaled, calibrated at-sensor radiance and are globally available.\n"]]
