Геологическая служба США Landsat 1 Коллекция MSS 2 Уровень 1 Необработанные сцены
Landsat 1 MSS Collection 2 Значения DN уровня 1, представляющие масштабированную, калиброванную яркость на датчике. Сцены Landsat с наивысшим доступным качеством данных относят к уровню 1 и считаются подходящими для анализа обработки временных рядов. Уровень 1 включает обработанные данные Precision Terrain уровня 1 (L1TP), которые…
Геологическая служба США Landsat 1 Коллекция MSS 2 Уровень 2 Необработанные сцены
Landsat 1 MSS Collection 2 Значения DN уровня 2, представляющие масштабированную, калиброванную яркость на датчике. Сцены, не соответствующие критериям уровня 1 во время обработки, присваиваются уровню 2. Сюда входят сцены, обработанные систематическим ландшафтом (L1GT) и систематическим (L1GS), а также любые сцены L1TP, которые…
