Landsat 8 Bands. Landsat 8 measures different ranges of frequencies along the electromagnetic spectrum – a color, although not necessarily a color visible to the human eye. Each range is called a band, and Landsat 8 has 11 bands. Landsat numbers its red, green, and blue sensors as 4, 3, and 2, so when we combine them we get a true-color image. Landsat 8 El 11 de Febrero de 2013, el vehículo Atlas-V que transporta el satélite LDCM (Landsat Data Continuity Mission) fue lanzado desde el buque USS Vandenberg. La nave fue diseñada para continuar el programa de captura global de imágenes espaciales que los Estados Unidos han estado implementando desde 1972 con la ayuda de la serie Landsat.

Landsat8卫星包含OLI(Operational Land Imager 陆地成像仪)和TIRS(Thermal Infrared Sensor 热红外传感器)两种传感器。 OLI包括了ETM+的所有波段,为了避免大气吸收部分特征,OLI对波段进行了重新调整,比较大的调整: 1、OLI Band5 (0.845-0.885 μm),排除了0.825μm处水汽吸收特征; 2、OLI全色波段Band8波段范围较窄,这种方式可以在全色图像上更好区分植被和无植被特征; 3、新增两个波段:海蓝波段 (band 1; 0.433-0.453 μm) 主要应用海岸带观测;短波红外波段,又称卷云波段 (band 9; 1.360-1.390 μm) 包含水汽强吸收特征,可用于云检测;. Feb 22, 2022 · Landsat 8 卫星于2013年2月发射升空,卫星搭载 OLI(Operational Land Imager 陆地成像仪)和 TIRS(Thermal Infrared Sensor 热红外传感器)两种传感器,每16天可以实现一次全球覆盖。 OLI 包括9个波段,空间分辨率为30米,其中包括一个15米的全色波段,成像宽幅为185x185km。 TIRS 用于收集地球两个热区地带的热量流失,能够了解所观测地带水分消耗。 Landsat 8 卫星有11个光谱带,11个光谱波段中有7个与 Landsat 7 上的 ETM+基本一致。 Landsat 8 波段包括蓝色、绿色、红色、NIR、SWIR-1、SWIR-2 和 30m 分辨率的卷云波段。. Landsat 8 diluncurkan pada 11 Februari 2013. Satelit pemantauan bumi ini memiliki dua sensor yaitu sensor Operational Land Imager (OLI) dan Thermal Infrared Sensor (TIRS). Kedua sensor ini menyediakan resolusi spasial 30 meter (visible, NIR, SWIR), 100 meter (thermal), dan 15 meter (pankromatik). Landsat 8 memiliki orbit Sun-Synchronous orbit.
